A series of studies were conducted to develop a labor-saving production system for carrot by developing seed coating techniques. Among the coaling materials tested in this study, diatomaceous earth #300 alone, or in combination with kaolin or with talc, was the suitable coating materials for carrot seeds. On the other hand, limestone alone, or in combination with other materials, greatly reduced germinability, using limestone as a coating resulted in as low as a low a 4% germination. Diatomaceous earth #300 was composed of Al, Si, K, Fe, and O. Oxidation products of diatomaceous earth were more 90% SiO2, 7% Al2O3, 6% Fe2O3, and about 1% K2O, and those of kaolin included 71% SiO2 and 21% Al2O3.

입고병균인 Phythium uitimum을 접종시킨 토양에 살균제를 첨가한 펠렛종자는 이를 첨가하지 않은 펠렛종자에 비해 묘출현이 현저하게 증가되었다. 두 품종 모 두 펠렛종자의 묘출현과 50% 묘출현에 소요되는 일수는 살균제의 종류보다는 처리농도에 의해 더 큰 영향을 받았다. 살균제 종류는 전반적으로 Redomil이 Captan보단 펠렛종자의 출현율 증진에 좋았다. 최적 살균제 첨가조건은·Redomil 1000mg ·L^(-1) 첨가였다. 유묘의 초기생육은 살균제가 첨가된 펠렛종자와 이를 첨가하지 않지 않은 펠렛종자간 유의성은 인정되지 않았으나, 전반적으로 살균제가 첨가된 펠렛종자에서 유묘생장이 높았다. Incorporating 1,000-ppm Redomil to pelleted seeds was helpful in establishing the stand in the Pythium-inoculated soil. When pelleted seeds were germinated in the soil inoculated with Pythium ultimum, percent seedling emergence was 26.4% for 'Inari' and 18.2% for 'Mansan' carrot. However, incorporating a fungicide, Redomil, into the seed being pelleted increased the percentages by 38.4% for 'Inari' and 39.5 % for 'Mansan'. Redomil incorporation did not increase percent emergence when planted in sterilized soils. Seedling growth measured 35 days after planting did not differ regardless of Redomil incorporation.

고추와 토마토 종자의 발아력 증진과 초기생육에 미치는 Osmotic Priming 및 Solid Matrix Priming 처리 효과

강점순,최영환,손병구,이용재,안종길,최인수,박현철 한국생명과학회 2003 생명과학회지 Vol.13 No.4

Osmotic priming과 SMP 처리과정 중 작물별 수분흡수율은 처리 후 3시간 이내에 대부분의 수분을 흡수하였다. 최종처리일의 두 처리간 종자함수율은 고추종자에서는 큰차이는 없었으나, 토마토에서는 osmotic priming이 SM보다 2.4% 높았다. Osmotic priming과 SMP 처리가 고추와 토마토에서 발아율을 향상시키지는 못했다. 그러나 osmotic priming과 SMP 처리 는 평균발아소요일수(MDG) 및 50% 발아에 소요되는 일수($T_{50}$)는 단축되어 조기발아를 유도하였다. 고추종자에서는 osmotic priming과 SMP 처리는 무처리 종자에 이하여 $T_{50}$이 $15^{\circ}C$에서 약 6일, $20^{\circ}C$에서는 약 5일, $25^{\circ}C$에서는 약 4.6일, $30^{\circ}C$에서는 약 4일 정도 단축되었고, 토마토 종자에서는 $15^{\circ}C$에서 3.3일, $20^{\circ}C$에서는 1.7일, $25^{\circ}C$에서는 1일,$30^{\circ}C$에서는 0.5일 정도 단축되었다. 이러한 발아촉진 효과는 불량발아 조건인 저온에서 뚜렷하였으나, 발아적온에 근접할수록 미약해지는 경향이었다. Osmotic priming과 SMP상호처리간 발아촉진 효과는 고추에서는 SMP 처리가 좋았고, 토마토에서는 큰 차이가 없었다. 종자처리 후 건조방법은 고추는 완전건조가 토마토에서는 표면건조가 조기발아 하는 경향이었다. Osmotic priming과 SMP 처리된 고추와 토마토 종자는 포장조건에서 묘출현을 향상시키지는 못했지만 출현속도를 단축시켜 신속한 묘출현을 유도하였다. 그러나 파종 후 35일 생육시킨 유묘의 초기생육은 osmotic priming과 SMP 처리에 의해 향상되는 경향이었으나 그 효과는 미약하였다. Osmotic and solid matrix priming treatments enhanced germination performance. We compared osmotic with solid matrix priming to determine the more effective treatment for improving seed germination in pepper and tomato. Seed hydration was immediately observed after osmotic priming and solid matrix priming treatment. The moisture content of solid matrix primed seeds was lower than that of osmotic primed seeds in the two vegetable crops. Osmotic priming and solid matrix priming did not increased percent germination, but showed shorter number of days to 50% of the final germination percentage ($T_{50}$) compared with untreated seeds, regardless of germination temperature. $T_{50}$ value was reduced in osmotic or solid matrix primed pepper seeds about 6.0, 5.0, 4.6 and 4.0 days compared with untreated seeds at 15, 20, 25, and $30^{\circ}C$, respectively. While, that in tomato seeds was reduced about 3.3, 5.0, 4.6 and 4.0 days compared with untreated seeds at 15, 20, 25, and $30^{\circ}C$, respectively. The effectiveness of osmotic priming or solid matrix priming in reducing the $T_{50}$ was greater when the seeds were germinated at $15^{\circ}C$ than at temperature of higher than $20^{\circ}C$. Solid matrix primed seeds germinated faster than osmotic primed seeds at all temperature in pepper. However, there was no significant difference on the percentage germination between solid matrix and osmotic primed seeds in tomato. After priming, dried-bark seeds showed faster germination than surface-dried seeds in pepper. On the other hand, there was no significant difference in tomato. Emergence of pepper and tomato seeds was markedly enhanced by osmotic priming or SMP treatment although the final emergence percentage was not significantly influenced. On the other hand, early growth was not significantly influenced by osmotic priming or SMP treatment of pepper and tomato seeds.

The purpose of this study was to identify for extenders, adhesives, colorants, and fungicides suitable for the production of high-quality film-coated seeds of Chinese cabbage. In addition, the effect of various additives used for film coating on the germination of coated seeds and seedling vigor was investigated to establish appropriate treatment conditions for film coating efficiency. The germination rate and germination speed in Chinese cabbage film-coated seeds did not differ significantly depending on the type and concentration of the extender, while the use of Talc resulted in superior granulation capacity and adhesion of the seed coat in comparison to Zeolite. There was no significant difference in the germination rate depending on the type of adhesive used for film coating of Chinese cabbage seeds, but the germination rate was slightly slower in the film-coated seeds using carboxymethyl cellulose as an adhesive. On the other hand, the seeds coated with a film using 1% PVA as an adhesive not only maintained hardness enough to withstand external pressure, but also showed a high germination rate. In addition, the suitable disinfectant for film coating was venoram, and the treatment concentration was good at 250 mg·L-1. The type of colorant used in the film-coated seeds of Chinese cabbage did not significantly affect the germination rate, germination speed, and seedling vigor. The seeds film-coated using the liquid colorant were superior in appearance to the seeds film-coated with the solid colorant, which implies the possibility of reduction in the manufacturing costs by using the water-soluble paints as colorants for film-coated seeds.

당근 펠렛종자의 파종효율과 유묘출현에 미치는 영향

강점순,조정래,임종민 한국생명과학회 2003 생명과학회지 Vol.13 No.4

This study was carried out to develop and investigate integrated mechanization system for culture of carrot. Compared with the conventional hand planting, use of a mechanical planter for pelleted seeds resulted in a saving of planting time by 225 hours. An additional saving of 460 hours was obtained for thinning the seedlings. Besides seeds could be saved by 72%, planting and thinning be done only in 35 hours per ha field when the pelleted seeds were planted with a planter. Work hour reduced by adopting the mechanical planting of pelleted seeds sharply contrasted to that of 720 hours required for hand-planting the thinning hours, resulting in a reduction of labor by more than 95%. SMP followed pelleting tended not only to increase the percentage of seedling emergence in the field but to induce an a day earlier germination. 펠렛종자를 점파용 파종기로 이용하여 기계화 정밀파종 함으로써 나종자를 손 작업에 의존하여 파종하는 것보다 파종시간과 솎음시간을 각각 225시간 및 460시간 절감할 수 있었고, 종자량도 72% 절감 할 수 있었다. 인력에 의한 손 파종은 파종과 솎음작업에 1 ha당 720시간이 소요되었으나, 펠렛종자를 이용한 기계화 파종은 35시간에 불과하였다. 따라서 펠렛종자를 기계화 파종함으로써 나종자를 인력에 의존하여 파종하는 관행방법에 비해 파종과 솎음작업의 생력효과를 95% 이상 높일 수 있었다. 펠렛종자의 묘출현율은 무처리 종자보다 출현율이 8% 정도 낮았고 출현속도도 약 1.9일 정도 지연되었으나 35일 경과된 유묘의 초기생육에는 큰 차이가 없었다. 유묘출현 반응은 품종에 따라 약간의 차이는 있으나, 펠렛종자는 나종자나 SMP 처리종자에 비해 출현율이 저하되었고 출현속도도 늦었다. 그러나 SMP 처리하여 종자활력을 증진시킨 후 펠렛하면 출현율도 향상되었고, 묘출현속도도 1일 정도 빨랐다.

The effect of plant growth regulators on perilla(Perilla ocymoides L.) germination was evaluated in the laboratory at 15℃, 20℃ and 25℃. Seeds of perilla cultivars 'Ipdulgge', 'Miryang', 'Yeupsil', 'Jukjaso' and 'Chungjaso' were dark-treated in varied level solution of gibberellic acid(GA3), 6-benzylaminopurine(BAP) and combined GA3 with BAP for a 1 day at 20℃. The effect of plant growth regulators varied among cultivar. Plant growth regulators treated did not affect percentage germination of all perilla seeds, but showed shorter number of days to 50% of the final germination(T50) and mean number of days to germination(MDG) than those untreated seeds. The germination behavior of all cultivar was highly correlated with plant growth regulators kinds and their concentrations. GA3 had to improve germination in 'Miryang', 'Yeupsil', 'Jukjaso' and 'Chungjaso', but the effect varied with applying level. GA3 250μ M treatment showed higher percent germination and shorter T50 and MDG of 'Ipdulgge' perilla than those of untreated, when the seeds were germinated at 15℃ , 20℃ and 25℃. When plant growth regulator treatment in 250μ M GA3 + 250μ M BAP of 'Miryang', in 250μ M GA3 of 'Yeupsil' and 'Chungjaso', and 100μ M GA3 + 100μ M BAP of 'Jukjaso' perilla seeds exhibited a faster rate of germination then those untreated seeds.

강점순 한국생명과학회 2002 생명과학회지 Vol.12 No.6

본 연구는 파 종자의 발아력을 증진시킬 수 있는 생장조절제 최적 처리조건을 구명하며, 파 종자 펠렛용으로 적합한 접착제 및 피복재료를 선발하기 위해 수행되었다. 식물생장조절제 종자처리는 발아율을 증진시키지는 못했다. 그러나 50% 발아에 소요되는 일수($T_{50}$)와 MDG는 단축되어 조기발아 하였다. 생장조절제 최적 처리조건은 500$\mu$M의 $GA_3$로 1일간 처리였다. 생장조절제 처리에 의한 발아촉진 효과는 발아적온보다는 저온인 $15^{\circ}C$에서 뚜렷하였다. 종자 펠렛의 접착제 종류 및 농도에 따라 발아율에는 큰 차이가 없었으나 발아속도는 대조구 종자에 비해 약 0.3~0.5일 지연 되었다. 종자 펠렛용 접착제의 농도가 증가하면 발아율이 약간 감소하였는데, 이러한 경향은 Carboxymethyl cellulose (CMC) 및 Methyl cellulose(MC)에서 뚜렷하였다. 종자 펠렛 접착제 가운데 Polyvinyl alcohol(PVA)와 Polyvinyl pyrrolidone(PVP)에서는 처리농도가 증가하더라도 발아를 크게 억제하지 않아, 파 펠렛종자 제조에 적용될 수 있는 최적 접착제였다. 펠렛 피복재료 중 kaoline, bentonite + kaoline 혼합물질 및 bentonite + CC + DME #300 혼합물질로 펠렛된 종자에서 높은 발아율과 발아세를 보여 파종자의 펠렛에 적합한 피복재료였다. This study was carried out to select new pelleting binder and material for Welsh onion seeds. The optimum treatments of the various plant growth regulators to improve seed germination of the Welsh onion was also estimated. There were no significant effects of growth regulators on the germination percentage, but germination was faster according to the number of days to 50% of the final germination ($T_{50}$) and the mean number of days to germination (MDG) than those of the control. Germinability was increased when the seeds were soaked in gibberellic acid ($GA_3$) solution for 24hrs, even though there was no synergy effect on the germinability when $GA_3$ was mixed with 6-benzylaminopurine (BAP). The optimum treatment for improving germination of Welsh onion was observed when the tested seeds was soaked in 500 $\mu$M of $GA_3$ at $20^{\circ}C$ for 24hrs. Also, when the seeds soaked in the aforementioned treatment, the rate of germination was increased at lower temperature than at $20^{\circ}C$, the optimal temperature. The percentage and the speed of seed germination depended on the kinds of pelleting binder and their concentration. It showed that the higher the concentration of the binder for seeds pelleting, the lower the percentage of seed germination. Among the pelleting binder, polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) were the best binders for seed pelleting, because seed germination using those binder did not affect on the concentration of binder. On the other hand, Carboxymethy cellulose (CMC) and methyl cellulose (MC) severely inhibited the seed germination The germinability was also different arcording to the pelleting materials. Among the different 58 pelleting materials, kaoline alone, the mixture of bentonite and kaoline, the mixture of bentonite, calcium carbonate and diatomaceous earth #300 were found as the best pelleting materials for welsh onion seeds.

토양함수율이 당근 펠렛종자의 묘출현율에 미치는 영향

펠렛 피복물질 중 diatomaceous earth는 입단 형성이 우수하였으나, calcium carbonate는 입단 형성이 불량하였다. Bentonite로 펠렛된 종자는 기계화 파종에 견딜 수 있는 경도를 보유하고 있었으나, calcium carbonate 로 펠렛된 종자는 기계화 파종하기에는 경도가 너무 낮았다. 펠렛종자의 출현율은 토양함수율과 펠렛 피복물질에 따라 차이가 있었다. 토양함수율이 60% 조건에서는 수분보온력이 높은 피복물질인 bentonite로 펠렛된 종자가 출현율이 높았고 출현속도도 빨랐다. 반면 100% 토양함수율에서는 calcium carbonate 펠렛된 종자들이 묘출현이 가장 높았다. 전반적으로 diatomaceous earth 로 펠렛된 종자는 토양함수율에 조건에 관계없이 높은 묘출현율을 보였다. Among the pelleting solid materials tested in this study, calcium carbonate and bentonite were characterized respectively by low and high water-holding capacity. The seeds pelleted with calcium carbonate emerged better in wet soil, whereas those pelleted with bentonite emerged better in dry soil. Result indicated the necessity of using different pelleting solid materials depending on water availability in the soil. However, the emergence of the seeds pelleted with diatomaceous earth was largely unaffected by soil water concentrations.
