참깨 종자의 발아율 향상 및 초기생육 촉진을 위한 priming 처리의 적정 조건을 구명하기 위하여 priming 약제 및 농도,priming 기간과 온도 및 priming후 저온 및 고온에서의 발아율에 대한 실험 결과에서 참깨 종자의 Priming에 가장 효과적인 약제는 PEG 6000, 농도는 −0.75MPa이었으며, priming처리 기간은 15에서 4일 처리하는 것이 가장 효과 적이었다.참깨 종자의 priming처리가 최종 발아율 향상에는 크게 기여하지 못했지만 초기 발아율 향상 및 T50 단축에 효과 적이었다. 참깨 종자의 Priming처리는 20oC 이상 보다는 15oC 저온에서 T50 단축에 효과적이었고, 발아율도 향상되어 재배적온보다는 저온하에서 Priming 효과가 극대화 될 것으로 판단된다. Priming 처리 후 건조 온도 조건에 따른 발아율에는 차이가 없어 25oC에서 3시간 정도 건조 시키는 것이 가장 경제적이었다. This experiment was carried out to investigate the effect of priming conditions on enhancing germination of sesame(Sesamum indicum L.) seed. The PEG 6000 with -0.75 MPa under 15oC for four days was most adaptable treatment for the establishment of optimum priming conditions of sesame seed under low and high temperature. Priming treatment of sesame seed showed to promote germination rate at the early stage to reduce the time of T50. Optimum treatment temperature was 15 rather than 20oC in view of T50 test. This experiment suggested that priming treatments to sesame seed were an effective technique enhancing seed germination and shortening time to the T50 at the field condition, but the efficiency would be strongly dependent on individual or integrated conditions of priming agent, concentration, temperature, duration as well as physiochemical seeds properties, meteorological condition.

김종덕(Jong Duk Kim),권찬호(Chan Ho Kwon),허삼남(Sam Nam Hur) 한국초지조사료학회 2008 한국초지조사료학회지 Vol.28 No.4

종자의 priming은 종자의 발아율 향상과 유식물의 초기정착에 중요한 기술 중의 하나이다. 본 시험에서는 목초의 주요 초종인 tall fescue, orchardgrass, alfalfa 및 white clover의 발아율 향상과 발아 균일도를 증가시키기 위하여 priming 처리기간과 처리온도에 따라서 목초의 발아율을 조사하였다. 본 시험은 분할구배치법으로 주구는 priming 처리시간으로 화본과 목초는 2일, 4일, 6일 및 8일을 두었으며, 두과목초는 l일, 2일, 3일 및 4일을 두었다. 세구는 priming 온도로 화본과 두과 목초 모두 10, 15 및 20℃를 두었다. Priming후 발아세, 발아율, 평균발아소요일수 및 T50은 초종과 priming 처리기간 및 온도에 따라 다르게 나타났다. Priming 처리기간에서는 화본과 목초인 툴 페스큐와 오차드그라스는 6일에 발아율이 높았으나, 두과목초인 알팔파와 화이트 클로버는 2일에 발아율이 높았다. 한편 priming 처리 온도에서는 오차드그라스는 온도가 낮아짐에 따라 발아율이 증가하였으나, 두과목초인 알팔파와 화이트 클로버는 온도가 10℃에서 20℃로 증가함에 따라 발아율이 증가하였다. 이상의 결과를 종합해 보면 목초의 priming은 초종에 따라 적정 처리시간 및 온도가 달랐다. Seed priming is an useful technique for increasing germination and early establishment of seedlings. In this experiment, the conditions for priming of pasture seeds (tall fescue, orchardgrass, alfalfa and white clover) have been optimized to ensure an early germination and more uniform growth of seedlings. The experiment was conducted in a split plot design with three replications. The main plots consisted of four different priming duration such as 2, 4, 6 and 8 days for grass, and 1, 2, 3 and 4 days for legume. The subplots were consisted of three priming temperature such as 10, 15 and 20℃. Effects of priming duration and temperature were different in all four pasture seeds examined. The germination of primed grass (tall fescue and orchardgrass) was the highest on 6 days in priming duration, whereas that of legume (alfalfa and white clover) was the highest on 2 days. In priming temperature, the germination of primed orchradgrass increased as decreasing temperature, however that of legume increased as increasing temperature. These results suggest that seed priming induced earlier and higher germination for all four pastures tested. However, the degree of priming effectiveness on pasture species depending on the priming duration and its temperature.

Priming과 파종후(播種後) 광질처리(光質處理)에 따른 도라지, 더덕, 만삼의 발아율(發芽率)

강진호,박진서,김동일 한국약용작물학회 1997 한국약용작물학회지 Vol.5 No.2

본 연구는 전보(前報)에 이어 초롱꽃과 약용작물 중에서 농가에서 재배되고 있는 도라지, 더덕, 만삼 종자의 발아 및 유근신장에 미치는 priming 방법(재료, 농도, 기간)과 Priming 후 발아과정에서의 광질(光質) (적색광(赤色光), 백색광(白色光), 암상태(暗狀態)) 효과(效果)를 조사하여 입묘율 향상에 관한 정보를 제공하고자 실시하였던 바 그 결과를 요약하면 다음과 같다. 1. 평균발아율(平均發芽率)은 priming 후 발아시 암조건(暗條件)에서는 도라지, 만삼, 더덕 순으로 감소하였던 반면, Priming 후 광질처리(光質處理)로 인하여 만삼에서는 발아가 억제되고 더덕에서는 발아가 향상되어 도라지, 더덕, 만삼 순으로 감소하였다. 2. 암상태(暗狀態)로 수행된 priming 처리에서 처리기간 간에는 차이가 없었다 할지라도 KNO3 보다는 Ca(NO3)2가, 무처리(無處理) 또는 타처리농도(他處理濃度)에 비하여 50~150mM에서 발아율과 유근신장이 향상되었다.3. Priming 후 광질처리(光質處理)로 인한 발아율은 도라지에서는 priming 유무(有無)에는 차이가 없었던 반면, 더덕에서는 발아초기에, 만삼에는 시간이 경과할수록 발아율이 향상되었다. 4. 발아중 백색광(白色光) 처리(處理)는 더덕과 만삼에서 발아를 억제하였는데 이러한 경향은 만삼에서 큰 반면, 도라지에서는 초기발아가 조장되는 것으로 나타나 초롱꽃과 약용작물의 발아는 priming 후 주어지는 광질(光質)에 따라 변화됨을 알 수 있었다. Priming has been used to establish a better standing in practice as controling the seed moisture content after sowing. The experiment was done to measure the effect of priming (material ; concentration ; period) and light quality (red ; white ; dark) after sowing on seed germination and radicle elongation of Campanulaceae (Platycodon grandiflorum ; Codonopsis lanceolata ; C. pilosula) to give an information on their earlier standing establishment. The germination test was carried out with 12 hours irradiation for 9 days after priming treatment. In the darkness, the mean germination rate of all the species was decreased in the order to P. grandiflorum, C. pilosula, C. lanceolata. Their germination and radicle elongation became more inclined when primed with Ca(CO3)2 or with 50 to 150mM than with KNO3 or no priming although there was no difference between priming periods. Under irradiation during their seed germination, however, the former order was changed to P. grandiflorum, C. lanceolata, C. pilosula because light quality treatment given after priming reduced the rate of C. pilosula but enhanced that of C. lanceolata. Although light quality forced after priming did not affect the mean germination rate of P. grandiflorum, it increased earlier or alltime germination of C. lanceolata or C. pilosula, respectively. White light after priming repressed germinations of C. lanceolata and C. pilosulai but increased earlier germinatin of P. grandiflorum, meaning that seed germination and radicle elongation of Campanulaceae could be determined by light quality treated after priming.

안종길,조동,손병구,최영환,강점순,최인수 密陽産業大學校 農業技術開發硏究所 1999 農業技術開發硏究所報 Vol.3 No.3

priming 처리제 및 농도에 따라 발아속도에는 차이가 있었는데, 고농도에서 발아속도가 지연되었으나, 저농도에서는 조기발아하였다. 적정 priming 처리제 및 농도는 PEG -0.50 MPa,였다. 무종자의 발아촉진에 최적 priming 조건은 20℃에서 24시간 처리였다. priming 종자는 발아적온 뿐만 아니라 불량발아 조건인 저온과 고온에서 발아력이 높았다. 묘출현율은 priming 처리가 무처리나 수침종자보다 8.1∼4.5% 높았으나, PEG 8000 -0.50 MPa + KH₂PO₄50mM 혼용처리간에는 유의성은 인정되지 않았다. 유묘출현 개시소요일수와 40% 유묘출현 소요일수는 종자처리에 관계없이 2일이 소요되어 종자처리간 차이는 없었다. 파종 25일후 묘생육은 PEG 8000 -0.50 MPa priming처리된 종자는 수침종자나 무처리종자보다 잎생육 촉진되었고 건물증이 증가하는 경향이나, 유의성인 인정되지 않았다. The purpose of this study was to evaluate seed priming influence on germination, emergence and seedling growth in radish. We observed the difference in germination speed on the kinds and concentration of priming chemicals. In the high concentration, we notified the germination was delayed, but in the low concentration, we noticed the germination was accelerated. The optimum concentration of priming chemicals was PEG -0.50 MPa. The optimum priming condition in radish was to treat the seeds for 24hrs at 20℃. The primed seeds showed the improved germination rate in the optimum condition as well as high or/and low temperature. We observed 4.5∼8.1% higher emergence of seedlings from primed seeds than those of non-primed and imbibed. There was no significant difference between PEG 8000 -0.50 MPa and PEG 8000 -0.50 MPa + KH₂PO₄50mM on emergence of seedlings. Start of emergence and days of 40% emergence of seedlings took for 2days regardless of seed treatment. Leaf growth and dry weight 25 days after sowing, were better from primed seeds with PEG 8000 -0.50 MPa than those of non-primed and imbibed.

강진호,강신윤,전병삼 한국자원식물학회 2000 한국자원식물학회지 Vol.13 No.1

현재 국내에서 시판되고 있는 어린 묘 중에서 가장 판매주수가 많은 것이 고추 묘로서 부가가치를 더욱 높이기 위하여는 발아와 균일성을 향상시켜야 할 것이다. 본 연구의 목적은 발아와 균일성 향상에 효과가 있는 priming 처리중의 광질처리와 발아온도에 따른 발아율의 변화를 추적하여 고추 공정묘 생산에 필요한 정보를 제공하고자 실시하였다. 대명고추 [(주)중앙종묘]와 왕고추[(주)동부한농종묘]를 공시품종으로 파종 전처리는 priming 제 [KNO$_3$; Ca(NO$_3$)$_2$], 농도 (0, 150, 300 mM), 처리기간 (0, 6, 12일), 광질 (적색, 초적색, 청색, 암)과 발아과정에서는 온도 (15, $25^{\circ}C$ 항온, 25/15$^{\circ}C$ 변온)를 달리하여 발아과정에서는 백열등으로 조사하면서 시험을 수행하였다. 시험결과를 요약하면 다음과 같다. 1. Priming제로서는 KNO$_3$보다는 Ca(NO$_3$)$_2$가 발아율을 향상시켰으며 최종발아율과 T$_{50}$은 공시품종 모두 Ca(NO$_3$)$_2$로 6~12일간 priming 처리하는 것이 처리하지 않는 것보다는 각각 증가되거나 짧아지는 경향을 보였다. 2. 발아온도 $25^{\circ}C$ 항온에서 파종 후 5일까지는 암상태에서 priming한 것에서 발아율이 가장 높았으나 파종 7일 이후에는 초적색광을 조사하면서 priming할 경우 가장 낮았다. 3. 발아율은 $25^{\circ}C$ 항온에서 가장 높고 15$^{\circ}C$ 항온에서는 현저히 억제되었으나 25/15$^{\circ}C$ 변온에서의 최종발아율은 $25^{\circ}C$ 항온에 근접하거나 동일한 것으로 나타났다. 4. 각 공시품종의 발아율은 priming 유무, priming 중에 처리되는 광질과 발아온도에 따라 변화되었으며 발아온도를 달리할 경우 파종 7일 후부터 priming중 적색광 처리시 발아율이 가장 높아 priming중의 광질효과도 발아온도의 영향을 받는 것으로 나타났다. Pepper (Capsicum annum L.) used as a spice or fruit vegetable has been transplanted for cultivation to accompany the production of its seedlings in general. The experiment was done to measure the effect of its cultivars (Daemyng; Wanggochu), priming (chemicals; concentration; period), light quality (red; far-red; blue; dark) during priming, and germination temperature (25 or 15$^{\circ}C$ constant; 25/15$^{\circ}C$ alternating) on the rate of germination done under incandescent lamps until 9 days after sowing. Seed germination was better when primed with Ca(NO$_3$)$_2$ than with KNO$_3$. Priming for 6 to 12 days using the former chemical enhanced the final germination rate and shortened the elapsed days to 50% germination, $T_{50}$, compared to no-priming. Under $25^{\circ}C$ constant germination temperature, primed seeds at darkness or far-red light showed the highest rate until 5 days after sowing or the lowest one since 7 days after sowing, respectively. The germination response at 25/15$^{\circ}C$ alternating temperature did not followed the lowest rate of 15$^{\circ}C$ constant germination temperature but inclined to that of $25^{\circ}C$ constant recorded the greatest one. Under 3 germination temperature red light treated during priming elevated the rate since 7 days after sowing compared to the other light treatments, and the germination rate of each cultivar was affected by no-priming or priming, light quality during priming. which imply their interaction to the seed germination.

만삼의 입묘율 향상을 위한 파종전 종자처리의 모형화

강진호,심영도,전병삼 한국약용작물학회 2001 한국약용작물학회지 Vol.9 No.2

환경조건이 불량한 산간고냉지에서 주로 재배되는 만삼은 종자의 구조적 결함으로 인한 발아율 저조로 입묘가 불량하게 됨으로서 재배에 실패하는 경우가 빈번하다. 따라서 파종전 종자처리를 통하여 만삼의 입묘율을 향상시키고자 종자의 발아와 관련이 있는 파종 후의 광조건을 고정한 후 priming, GA3, 건조, 침종 등 파종전 종자에 손쉽게 가할 수 있는 처리의 효과를 구명하고 이들 처리를 모형화하기 위하여 본 연구를 실시하였던 바 그 결과를 요약하면 다음과 같다. 1. 발아율은 0.1 mM에 3일간 1일 12시간의 청색광 또는 적색광을 가하면서 GA3를 처리하는 것보다는 적색광 또는 암상태에서 CA(NO3)2 150 mM에 2일간 priming 처리하는 것에서 높았다. 2. Priming중에 처리용기를 교반시키거나, priming 후에 행하여지는 세척이 발아율을 향상시키는 것으로 조사되었다. 3. Ca(NO3)2 150 mM에 2일간 priming처리된 만삼종자의 최적건조 방법은 빛이 없는 암상태에서 35℃에 4시간 건조하는 것이 가장 양호한 발아율을 보였다. 4. Priming 후에 건조처리된 종자는 파종 직전 2일간 침종하여야만 발아율과 유묘출현율이 가장 높은 것으로 나타났다. 5. 이상의 결과로부터 만삼의 입묘율을 높이기 위한 파종전 종자처리는 20℃에서 1일 12시간의 적색광을 가하면서 Ca(NO3)2 150 mM에 2일간 처리용기를 흔드는 방법으로 priming된 종자를 물에 세척한 후 35℃에서 4시간 적색광을 처리하여 건조한 다음 파종 직전 20℃의 물에 2일간 침종하는 과정으로 요약된다. Germination of Codonopsis pilosula seeds and afterward their seedling emergence have been occasionally very poor due to their dormancy and structural defects. The study was done to determine the treatment effects of priming, GA3, agitation and washing during and after priming, drying and water imbibition after drying on germination of its seeds and then of the successive three combined treatment after priming on the its seedling emergence to model its presown seed treatment. While agitation at the speed of 10 rpm was made or not, priming using Ca(NO3)2 and GA3 under their different concentrations and light quality illuminated for 12 hours a day were done separately. Then their two best results were compared to determine the better one. Using the above determined best result, washing was done 3 minutes in the tap water or not, and drying of washed seeds was made under 4 different lights, and water imbibition of the dried seeds with differed period were successively done to deduce its presown seed treatment. In the comparison of the best germination rate of priming and GA3, the former showed considerably higher rate than the latter; the priming treatment was done at agitated Ca(NO3)2 150 mM solution under darkness or 12 hour red light illumination a day for 2 days. Washing after priming enhanced the rate compared to no-washing. Drying was the best way at which seeds washed were desiccated under 35℃ and 4 hour red light illumination. Water imbibition immediately before sowing must be made for 2 days. Seedling emergence rate was the highest at the seeds from successive 4 treatments, priming, washing, drying and water imbibition before sowing of two others, the priming and washing, or the priming, washing and water imbibition, meaning that its presown seed treatment must follow the procedure of the above 4 successive ones.

Hyun Jin Kim(김현진),Hyun Hwan Jung(정현환),Ki Sun Kim(김기선) 한국원예학회 2009 원예과학기술지 Vol.27 No.1

벌개미취 종자는 저온 조건에서 낮은 발아를 보이거나, 불균일하게 발아한다. 저온 하에서 벌개미취 종자의 발아를 향상시키기 위해서, 적정 프라이밍 처리 조건을 조사하였다. 벌개미취 종자를 12℃에서 발아시켰을 때, KNO3–프라이밍은 최종발아율을 향상시켰다. KNO3의 농도가 높아짐에 따라 최종발아율은 증가하였으나, 처리한 세 농도(0.1, 0.2, 또는 0.3M KNO₃) 사이간에는 유의성이 존재하지 않았다. Non-priming과 비교해볼 때, 15℃-priming은 12℃에서 최종발아율을 32%에서 83%로 증가시켰다. 그러나, 30℃-priming은 12℃에서 최종발아율이 43%였으며, non-priming과 통계적 유의성을 보이지 않았다. 프라이밍 처리한 후, 20℃에서 24시간 동안 건조 처리한 종자의 최종발아율과 평균발아소요일수는 프라이밍 처리후에 건조 처리하지 않은 종자의 최종발아율, 평균발아소요일수와 비슷하게 나타났다. 결과적으로 벌개미취 종자를 0.1M KNO₃와 15℃에서 3일 동안 프라이밍 처리하면 저온 하에서도 종자발아를 크게 향상시킬 수 있다는 것을 알 수 있었다. 본 실험의 결과를 바탕으로 초봄에 벌개미취를 파종하기 전에 종자의 프라이밍 처리를 함으로써 벌개미취를 빠르게 조성시킬 수 있을 것으로 기대된다. Gymnaster koraiensis (Nakai) Kitam. seeds had low germination or lack of germination uniformity under low temperature conditions. To improve the final germination percentage (FGP) of G. koraiensis seeds under low temperatures, we investigated proper priming treatments. Priming with KNO₃ solutions enhanced FGP when G. koraiensis seeds were germinated at 12℃. As the concentration of KNO3 rose, FGP was increased, but there was no significant difference among the three concentrations (0.1, 0.2, or 0.3 M KNO₃). Compared to non-priming, 15℃-priming increased FGP from 32% to 83% at 12℃. However, FGP in 30℃-priming was 43% at 12℃, and there was no statistical difference with non-priming. FGP and the mean time to germination of seeds dried at 20℃ for 24 hours after priming were similar to those of non-dried seeds after priming. From the above results, we could conclude that the priming with 0.1 M KNO₃ at 15℃ for three days promoted the germination of G. koraiensis seeds under low temperature regimes. The present results suggested that priming treatment prior to sowing in early spring could rapidly establish G. koraiensis seedlings.

최낙환(Choi, Nak Hwan),김익태(Kim, Ik Tae) 한국소비문화학회 2010 소비문화연구 Vol.13 No.4

이 연구는 노출된 단서가 과거의 행동패턴이나 습관과는 다르게 차별화 되는 경우에 점화된 내용과 일치하는 행동이 유발되는가 아니면 불일치한 행동이 유발 되는가를 검증하고, 또 소비자의 제품 지식수준에 따라서 점화의 효과가 조정되는가를 탐색하였다. 따라서 이 연구는 점화의 행동효과와 무의식적 목적추구에 관한 선행 연구를 탐색하고, 소비자의 제품 지식수준과 과거 행동패턴과 점화된 상황의 독특성 또는 차별성에 따른 목적점화의 조절효과를 분석하였다. 연구결과, 어머니 생신 선물을 구매하는 상황에서 검소와 관련된 점화자극에 점화된 피험자는 검소와 관련된 제품을 더 선택하는 모습을 보였고, 사치와 관련된 점화자극에 점화된 피험자는 사치와 관련된 제품을 더 선택하는 모습을 보였으며, 일반적이지 못한 차별적 상황에서 목적점화의 효과는 조절되는 것으로 나타났다. 그리고 개인들이 제품에 대하여 가지고 있는 지식수준에 따라 점화의 효과가 조절되었으며, 행동패턴도 조절작용을 하였다. 따라서 점화된 목적은 목적과 일치한 행동을 유도하며, 점화효과는 상황의 독특성, 소비자가 가지고 있는 제품에 대한 지식수준, 그리고 개인들의 행동패턴에 따라 조절될 수 있음을 발견하였다. The purpose of this study is to search for the moderators such as the consumer's knowledge, the past behavior patterns, and uncommoness or distinctiveness of the situations of goal priming effects. This study frames an hypothesis on the product choice effect of goal priming, and the level of consumer's understanding goods, and the distinctiveness of primed situation and consumer's past behavior pattern were selected as a variable of moderating goal priming effects. The hypotheses were tested by using the subjective measure, and the distinciveness of primed situation was detected by using two cases : one is to give a present to mother on her birthday and the other is to friend on the birthday. and the case of friend's birthday was looked upon as uncommon context. Besides, to test roles of the past particular behavior patterns on the assumption that consumers keep the same behavior patterns as they have done, past behavioral patterns were detected. The results of testing hypotheses are as follows. First, the primed goal showed that it induced a prime-consistent behavior. In case of woolen gloves and leather gloves as a gift for mother, thrifty priming led the participants to choose the woolen gloves more, and luxury priming to choose the leather gloves more. In the result, the priming generated by an accidental exposure had an influence on product-choice and individual's behavior. Second, the effect of goal priming turned out to be affected by uncommon context and to be moderated in the distinctive context. Mother's birthday present brought out more priming effect than that of the friend's birthday did, that is, uncommon context weakened the effect of goal priming. These results indicate that individuals are affected by environmental uncommon context like the unexperienced situations. Third, in proportion to consumer's information level of goods, goal priming was affected differently and then priming effect was moderated. In other words, priming effect with the luxury priming was higher than any other case to the consumers who had a high information level of goods, and in the priming situation the information level of goods could play a moderating role. Fourth, the effect of goal priming was moderated by individuals` behavior patterns. Goal priming had an impact on choosing the gift according to the past behavior patterns. The consumer who purchased expensive goods as mother's birthday gift in the past showed more priming effect in luxury priming than all the other cases. Therefore, the effect of goal priming was moderated by the past behavior pattern.

Pre-Sowing Seed Treatment: Effect of Deep Sea Water Priming on Germination of Wild Vegetables; Gondalbi (Cirsium setidens), Jandae (Adenophora triphylla var. Joponica Hara) and Deoduck (Codonopsis lanceolata Trautv.)

Yoon Byeong-Sung,Shrestha Surendra Lal,Kang Won-Hee The Plant Resources Society of Korea 2006 한국자원식물학회지 Vol.19 No.6

This experiment was conducted on wild vegetables; Gondalbi (Cirsium setidens), Deoduck (Codonopsis lanceolata Trautv.), and Jandae (Adenophora triphylla var. Joponica Hara) seed to study whether priming with deep sea water results in enhancement of seed germination and identify the optimum concentration of the priming solution, and duration of priming. Seeds were primed with 5 various concentrations (5%, 10%, 15%, 20% and 30%) of deep sea water (DSW) in 12 hours, 24 hours, and 48 hours at $24^{\circ}C$. Since Jandae had seed dormancy, it was kept for four weeks in refrigerator at $2^{\circ}C$ after priming treatment. In Deoduck, 5 percentage DSW priming significantly improved the early germination percentage, radicle length, and plumule emergence percentage. Among the priming period of treatments, 24 hours priming showed better performance in this treatment whereas, in Jandae, 12 hours priming with 10 percentages DSW significantly improved the germination percentage and germination rate. This treatment had increased the final germination percentage by 54%, 15% and 40% compared with control, plain water and $KNO_3$ priming respectively. But in Gondalbi, priming did not improve the germination of seed. However, among the priming treatments, 12 hours priming with 3% $KNO_3$ and 20% DSW gave better performance. In both the wild vegetables; Deoduck and Jandae, priming in deep sea water had improved the germination percentage and germination rate as compare to plain water, $KNO_3$, and without priming treatment. Hence the best seed priming treatment on Deoduck and Jandae are 24 hours with 5% DSW and 12 hours with 10% DSW respectively.

신속하고 균일한 묘출현 증진을 위한 종자전처리 기술

조동,손병구,강점순,최영환,안종길 密陽産業大學校 農業技術開發硏究所 1998 農業技術開發硏究所報 Vol.2 No.1

Preplant seed hydration treatments, particularly at low water potential, mobilized seed's resources that are utilized for rapid and synchronous germination, improved emergence rare, and larger stand size and yields. Seed priming is ideally suited to combat or lessen the impact of a number of soil and climatic constraints, including cold and wet conditions, thermoinhibition, drought, and incidence of diseases. The priming treatment is versatile enough to be integrated with other preplant physiological and non-physiological treatment to combat other internal and external constraints. These include chilling to break the primary dormancy, permeation with hormones to prevent the induction of secondary dormancy, and treatment with pesticides and beneficial microbes to combat seed and seedling diseases during stand establishment. The success or failure of priming treatment are influenced by a complex interaction of factors including plant species, osmeticum, water potential of the priming agent, during of priming, temperature, seed vigor, and dehydration and storage conditions following priming. Seed priming treatment under controlled temperature conditions, allows seeds to imbibe water and go through the initial stages of germination without radicle protrusion through seed coat. The use of a matricum for solid matrix priming(SMP) follows the same principals as for solution osmotic priming. The choice in mainly based on choosing a material wherein water uptake by the seed can be more closely regulated. Concentration of the matricum or osmoticum can be altered to fine-tune water relations The other factors that effect the results from seed priming, aeration, temperature, duration, light. dehydration, and storage are dependent on the species being primed. All crop seeds need air to germinate, thus optimizing aeration during priming. Germination rate and uniformity can be improved by priming for a vast array of crops as evidenced. The numbers of different species commercially primed and available to producers is quite small. The reasons for this might include the high charges to the grower of primed seed, lack of knowledge and or experience by growers of the results obtained from priming. Finally, more practical and essential subjects such as seed vigor and priming effectiveness, effects of dehydration after priming, storage conditions, and the ideal combination of matrix-solid, water, and seeds in SMP treatments are in need of further studies.
