There is little information about propagation of the cutting and seed, and management after propagation. To investigate the effective propagation method, cuttings of Clematis were collected and cutting experiment was performed at the greenhouse. Stem cutting lengths were 1 node and 2 nodes and peatmoss, perlite, and vermiculite were used as rooting media. IBA (4,000 mg·L -1 soaking for 5 seconds and 500 mg·L -1 soaking for 30 minutes) and Rootone TM were used as rooting promoter. Rooting rate of clematis cuttings usually took about 10 weeks. The 1-node cuttings increased the rooting rate by about 43% compared to 2-node cuttings. Rooting percentage of 1-node cuttings increased in the Rootone TM treatment about 7% more than in the control group. Using 1-node cutting is more effective in terms of the amount and management of the cuttings. Meanwhile, the rooting rate, and number and length of adventitious roots were largest in vermiculite and IBA 4,000 mg·L -1 soaking for 5 seconds. Thus, when 1-node cuttings were stuck in vermiculite, rooting rate increased to about average 80-83%. Also, rooting rate in vermiculate is 25-29% and 13-39% higher than in peatmoss and perlite, respectively. Cutting in vermiculite increased by 9-13% after soaking into IBA 4,000 mg·L -1 for 5 seconds and was found to be the most effective media and rooting promoter.

To investigate the characteristics of plant growth and flower quality of gerbera 'Sunny Lemon' by amount of nutrient solution, young seedling plants, 'Sunny Lemon' were transplanted to rock-wool and medium of peat moss and perlite mixed with 1 to 2 and they were acclimatized in greenhouse during about 1 month. Nutrient solution supplied to the plants is sonneveld solution of 1/2 concentration and treatments launched June 24, 2010 when average plant height was 20±1cm. Nutrient contents as a standard for starting point of irrigation by time domain reflectometry (TDR) were determined with 60-65%, 70-75%, and 80-85%. Results of growth during vegetative growth, plant height, leaf width and leaf number increased by 10% in rockwool, but they were not significantly different. As for plant growth depending on nutrient content, 80-85% treatment showed the highest values. Leaf number increased by 60%, and leaf width and plant height had a about 40% increase than initial growth. Effectiveness for flower quality, yield and days to flowering were superior when nutrient content of media was higher than in the others. Especially, average days to flowering in 80-85% content was advanced by 7-10 days compared to the day in 60-65% treatment. The total amount of nutrient supply per plant was higher in mixed medium than in rockwool, but change patterns of EC and pH were enhanced in rockwool. Based on our results, we recommended that growth, cut flower, and yield of gerbera 'Sunny Lemon' were more effective when nutrient content of mixed medium was maintained at 80-85%. 거베라 ‘Sunny Lemon'의 양액재배시 양액함량 조절이 생육 및 절화특성을 알아보고자 미치는 영향을 알아보고자 입상암면과 피트모스와 펄라이트 혼합배지(2:1, v/v)에 거베라 'Sunny Lemon' 유묘를 정식한 후 약 1달 동안 온실에서 순화시킨 후 배지내 양액의 함량이 각각 80-85%, 70-75%, 60-65%로 유지되도록 TDR센서(UT-TM, Ultra-Tech., Korea)를 부착하여 지속적으로 공급되도록 하였다. 양액은 거베라 sonneveld 양액을 1/2농도로 조성하여 초장이 평균 20±1 cm인 6월 24일 개시하였다. 영양생장에서 생식생장 전환 시점인 2개월 후 거베라의 생육을 조사한 결과, 배지종류에 따라서는 입상암면이 혼합배지보다 초장, 엽폭 및 엽수가 약 10% 더 증가되었지만 통계적으로 유의성은 없었다. 급액함량에 따라서는 2가지 배지 모두 배지내 양액 공급함량이 80-85% 때 가장 생육이 좋았으며, 생육초기보다 엽수는 약 60%이상, 엽폭과 초장은 약 40%정도 증가되었다. 첫 개화시점, 절화 품질 및 수량은 배지내 양액 함량이 높을수록 양호하였으며, 개화시점도 배지내 양액함량이 60-65%일때 보다 약 7-10일 빠른 것으로 조사되었다. 총 급액량은 입상암면보다 혼합배지내의 양액함량을 80-85%로 유지시킬 때 더 많이 소모되었으나, 배지의 EC, pH 변화는 입상암면에서 큰 것으로 보아 1회 정식 후 3년이상 재배되는 거베라 'Sunny Lemon'의 생육, 절화 품질 및 수량은 혼합배지에서 급액함량을 80-85%로 유지하여 재배할 때 가장 우수한 것을 알 수 있었다.

This study was performed to investigate the possibility of water cutting by vegetative propagation methodfrom July to August of Clematis. To find out proper cutting length and rooting growth regulator for water cuttingsproduction, cutting lengths of C. ‘Honora’ made 1 node and 2 nodes length cutting, which were soaked in NAA0.1mg·L−1. Rooting rate of cuttings treated by NAA 0.1mg·L−1 was 100% irrespective of root lengths, but that of 1node and 2 nodes untreated by NAA 0.1mg·L−1 were very low about 30% and 19% respectively. Number of rootsand roots length were also highest in NAA 0.1mg·L−1, effects of NAA 0.1mg·L−1 treatment were greater at 1 nodecutting. Based on the results, rooting rate for I node cutting of C. ‘Pairu’ according to NAA (0, 0.1, 0.5, 1.0mg·L−1)concentrations was investigated. Days to rooting were 70-74 days (about 10 weeks), which was not significantly differentamong the NAA concentrations. Rooting rate increased by NAA concentration. it was about 90% usually andwas improved with more than NAA 0.5mg·L−1. 클레마티스의 경삽에 의한 삽목번식이 잘 되지 않는7-8월의 영양번식방법으로 수삽의 가능성을 알아보기 위해 실험을 수행하였다. 수삽시 적정한 삽수길이 및 발근제 처리효과에 대해 알아보기 위해 클레마티스 ‘호노라’의 1마디 삽수와 2마디 삽수를 NAA 0.1mg·L−1에 처리하였다. NAA 0.1mg·L−1 처리구는 삽수길이에 관계없이100% 발근되었지만, 무처리구는 1마디, 2마디 삽수 각각 약 30%와 19%로 발근율이 현저히 낮았다. 뿌리수,뿌리길이도 NAA 0.1 mg·L-1 처리구가 우수하였고, 그효과는 1마디 삽수에서 더 크게 나타났다. ‘호노라’ 수Fig. 5.

길미정,허은주,권영순,Kil, Mi-Jung,Huh, Yeun-Joo,Kwon, Young-Soon 한국원예학회 2011 원예과학기술지 Vol.29 No.6

$GA_3$에 의한 화아수 증진효과는 산호수 1년생, 생장조절제의 종류 및 농도에 따른 착과, 비대 및 착색 증진효과는 산호수 2년생을 사용하여 본 실험을 수행하였다. 그 결과, 화아수는 $400mg{\cdot}L^{-1}$ 처리구에서 가장 많았으며, 이는 대조구보다 약 1.8배 많이 형성되었다. 착과율 증진을 위해 산호수 만개시기에 생장조절제를 처리한 결과, $GA_3$와 auxin처리구의 착과율이 증진되었으며, 이 중 $GA_3$가 더 효과적이었다. $GA_3$에 의한 착과율은 0.5와 $1.0mg{\cdot}L^{-1}$ 처리시 각각 약 70%와 77%로 대조구보다 약 1.8배 증가되었다. 또한 Auxin 중 Dichloprop triethanol amine도 약 7-12%가 향상되었지만, cytokinin과 anti-GA는 효과가 없었다. $GA_3$에 의한 산호수 열매 비대효과를 알아보기 위해 만개 2달 후 열매 지름이 약 2-3mm되었을 때 0.3, 0.6, $1.2mg{\cdot}L^{-1}$를 1달 간격으로 3회 처리한 결과, $0.6mg{\cdot}L^{-1}$에서 약 15% 향상되었다. 그러나, 과피의 안토시아닌 측정에 의한 착색정도는 $GA_3$ 처리농도에 따라 유의한 차이가 없었다. 즉, 산호수에 있어서 $GA_3$는 화아수, 착과, 열매 비대를 증진시키는데 효과적인 것으로 나타났다. The objective of this study was carried out to investigate the proper plant growth regulator for increasing the number of flower, fruit set, and to enlarge the size of the berries in Ardisia pusilla. Flower bud formation was used rooted cutting, and fruit set, enlargement, and coloration of fruit were used with two years-old. $GA_3$ concentrations were treated with 0, 100, 200, or $400mg{\cdot}L^{-1}$. Flower bud formation was effective in $400mg{\cdot}L^{-1}$ $GA_3$ and it was 1.8 times greater than control. Plant growth regulators were applied by foliar spray at full bloom stage to increase the fruit set. As a result, $GA_3$ was the most effective for increasing fruit set. Also, auxins of 4-CPA (Tomatotone, Donbu hitech Co., Korea) and dichloprop triethanol amine (Antifall, Bayer Crop Science Co., Ltd., Korea) were effective. When $GA_3$ concentrations of 0.5 and $1.0mg{\cdot}L^{-1}$ were used, fruit set (%) reached to 70% and 77%, respectively. Effectiveness of $GA_3$ was 1.8 times greater than control. Also, auxins, dichloprop triethanol amine increased to about 7-12% during fruit setting, but cytokinin and anti-gibberellin were ineffective. To investigate the fruit enlargement and coloration, $GA_3$ was treated with 0.3, 0.6, and $1.2mg{\cdot}L^{-1}$. Fruit enlargement was achieved to about 15% by $GA_3$ $0.6mg{\cdot}L^{-1}$ when $GA_3$ was treated 3 times at the interval of 1 month per treatment when fruit size was about 2-3mm (after full-blooming two months). But anthocyanin contents for coloration of fruit skin were not significant according to $GA_3$ concentration. The results showed that $GA_3$ enhanced bud formation, fruit set and enlargement of fruit size in Ardisia pusilla.

길미정(Mi Jung Kil),최성열(Seong Youl Choi),권영순(Young Soon Kwon) (사)한국생물환경조절학회 2012 생물환경조절학회지 Vol.21 No.4

온도에 따른 왜화효과를 알아보기 위해 죽절초 1년생과 3년생 각각을 2011년 1월 3일부터 광도 500 ± 20 lux, 상대습도가 40 ± 5%로 유지되는 5℃, 10℃, 15℃, 20℃의 생육상에 약 120일간 처리한 후 즉시 유리온실(50% 차광)에 입실시켜 60일 동안 계속 재배하였다. 그 결과 죽절초 1년생은 5℃ 처리에서 초장증가율이 가장 낮아 왜화에 효과가 있었지만, 생육상태는 양호하지 않았다. 10℃ 처리의 초장은 약간 신장하였지만, 엽수와 엽폭이 가장 많이 증가되어 미관상 생육이 가장 양호하였다. 15℃와 20℃ 처리는 초장이 오히려 감소되고 하엽이 지는 등 생육이 좋지 않았다. 따라서, 죽절초 1년생의 소형화를 위해서는 10℃가 가장 적정한 온도로 생각된다. 3년생 죽절초의 초장은 처리온도가 높을수록 증가하였고, 초장 신장률은 5℃와 10℃, 15℃와 20℃ 처리구가 서로 비슷한 경향을 보였다. 엽수는 5℃에서 가장 많이 증가하였다. 한 마디당 측지도 5℃와 10℃는 많이 발생한데 비해 15℃와 20℃는 거의 발생하지 않았다. 또한 5℃와 10℃ 처리구는 8월말까지 각각 약 90%와 60% 이상 개화되었지만 15℃와 20℃는 거의 개화되지 않았다. 위 결과로 보아 1년생과 3년생 죽절초를 소형분화로 상품화하기 위한 왜화 온도는 각각 10℃와 5℃가 가장 적정한 것으로 판단된다. The purpose of this study was to examine the dwarfing effect in variable temperature treatments on 1-year-old and 3-year-old Chloranthus glaber. The plants grown in four difference growth chamber under a mean light intensity 500 ± 20 lux, RH of 40 ± 5%, and temperature of 5℃, 10℃, 15℃, and 20℃ for 120 days from January 3, 2011. And then they were moved into a glass house (50% shading). In 1-year-old seedlings, the rate of plant height elongation was lowest at 5℃, but plant growth was not good. The number of leaves and leaf width were highly increased by 10℃ treatment although the plant height was slightly increased. Also the plant height of 15℃ and 20℃ was decreased and defoliation was started from the bottom leaves. Thus, 10℃ treatment was thought to be the most appropriate for dwarfing effect of 1-year-old seedlings. In 3-year-old seedlings, the plant height tended to increase with temperature, and growth pattern showed a similar trend between 5℃ and 10℃, 15℃ and 20℃. The number of leaves increased the most at 5℃. Lateral branches per node were mainly occurred at 5℃ and 10℃, whereas they almost didn’t happen at 15℃ and 20℃. Flowering rate at 5℃ and 10℃ reached more than 90% and 60%, respectively, but it was too low at 15℃ and 20℃ until the end of August. From these results, it could improve plant quality of 1-year-old and 3-year-old Chloranthus glaber making compact potted plants when temperatures were maintained at 10℃ and 5℃, respectively.
