지성한 한국인간·식물·환경학회 2008 인간식물환경학회지 Vol.11 No.4

본 연구는 배지, Rooton 및 삽수경화정도가 6품종의 라벤더삽수의 발근 및 생장에 미치는 영향을 조사하였다. 발근율은 `프린지드`와 `마리노`에서 각각 88%와 100%로 가장 높았으며, `피나타`와 `빅토리오`의 발근율은 현저히 낮게 나타났다. Rooton 분말처리는 대부분의 품종에서 발근율 뿐만아니라 뿌리생장에 있어서도 긍정적인 효과를 보였다. 특히 `빅토리오`의 경우 Rooton 처리에 의해 발근율이 0%에서 82%로 크게 증가하였다. 한편 Rooton 처리가 지상부생장에 미치는 효과는 미비한 것으로 나타났다. 잉글리쉬와 프린지드는 펄라이트에 비해 피트모스배지에서 발근율과 뿌리생장이 뛰어난 것으로 판명되었다. 한편 녹지삽과 반숙지삽에 의한 발근 및 뿌리생장 결과는 통계적으로 유의성이 없었다. 이상의 결과로부터 라벤다를 이용한 원예치료 삽목프로그램시 적합한 품종으로는 ‘프린지드’와 ‘마리노’를 추천한다. 또한, 라벤다 삽수에 Rooton 분말을 묻힌 후 피트모스배지에 삽목하는 것이 발근율을 높힐 수 있는 효과적인 방법임을 알 수 있었다. This study was conducted to investgate the rooting media, rooton and cutting hardeness on the rooting and growth for 6 different cultivars of Lavandula officinalis using stem cuttings. The rooting rate was highest with `Fringed` and `Marino` lavender in 88 and 100% respectively, but that was restricted with `Pinata` and `Victorio` lanvender. Treating cutting with Rooton powder was effective promoting root growth as well as rooting rate in the most of the cultivars. In particular, the rooting rate of `Victorio` lanvender was increased from 0 to 82% by Rooton treatment. However, the effect of Rooton tratment on the shoot growth was not recognized in 3 different lavenders. `English` and `Fringed` lavender on the cutting peatmoss media were superior in the rooting rate, root number and root dry weight than the perlite media. On the other hand, there is no significant differences in root number and root dry weight between soft wood cutting and semi-hardwood cutting within same varieties. In these results were suggested that `Fringed` and `Marino` lavender are more suitable for succesful cutting program of Horticultural Therapy using lanvender. And then the treatment cutting with rooton powder on the peatmoss media is effective method to promote rooting rate in Lavendular spp.

This study was carried out to investigate the effects of shading and nutrient solution levels on growth and fruit yield in hydroponically grown tomato (lycopersicon esculentum MILL.cv. 'Seogwang') plants. The effect of vegetative growth control by low concentration of nutrient solution was decreased as the shading level increased. Higher shading level increased to LAI(Leaf Area Index), but decreased to NAR(Net Assimilation Rate). On the other hand, the distribution rate of drymatter in vegetative organs such as leaf and stem was higher than that in fruit. The result obtained this experiment demonstrated that condition of light was more effective than concentration of nutrient solution on growth and fruit yield of tomato plants.

窒素 水準이 水耕토마토의 營養生長과 果實 收量에 미치는 影響

池性韓 호남대학교 1992 호남대학교 학술논문집 Vol.13 No.-

Tomato(Lycopersicon esculentum MILL. cv Ogatazuiko) plants were grown in the water culture solution at five levels of nitrogen (2∼32me) which were maintained by the addition of sodium nitrogen. The hignest fruit yield was obtained at 8∼16me N. In the rang 2∼16me N, the nitrogen level accelerated plant growth and increased nitrogen content of the leaves. There were no significant differences in vegetative growth and nitrogen content of the leaves between plants from the 16me and 32me N However, the fruit yield and potassium content of the leaves obtained from 32me N was 19% and 17% lower than those from 16me N respectively. The highest dry matter distribution of the leaf was achieved at 16∼32me N, but that of theroot was showed at 2me N. The results obtained here demonstrated that 8 me M is thought to be suitable for controlling excessive vegetative growth without the loss of fruit yield. The data presented suggest an optimum of 8∼16me N.

마늘의 추대 및 맹아억제에 미치는 액아단 약제의 효과를 구명하기 위해 본 실험을 실시 하였다. 처리농도는 무처리, 1/150배, 1/100배 및 1/50배로 5월6일과 수확 1주일전인 6월8일에 엽면살포하였다. 추대방지에 미치는 액아단의 엽면살포효과는 인정되지 않았으나 처리 농도가 높을수록 맹아율은 현저하게 억제되어, 본 연구의 결과로부터 마늘의 맹아억제를 위한 액아단의 최적 엽면살포 처리농도는 1/50배인 것으로 판명되었다. The effect of foliar spray of 'Aekadan' on bolting, greening and inhibition of sprouting in garlic was investigated. Aekadan was treated with 4 different concentrations(0, 11/150x, 1/100x, and 1/50x) at May 6th and June 8th which was a week before harvesting. There was no significant differences in bolting but sprouting rate was decreased from 4 to 30% with the increasing treatment concentration. The result obtained by this experiment demonstrated that 1/50 concentration of 'Aekadan'is most suitable for inhibition sprouting of garlic.

오이(Cucumis sativas L. cv. seolok chungjang)의 육묘시 초장조절을 위하여 주야간 온도차 (DIF)에 따른 9조합 처리를 4주간 실시하였다. 주야간 온도차 처리에 따른 오이묘의 초장은 주간온도가 증가함에 따라 증가하였고 동일 일평균온도조건하에서는 -DIF에 의해 억제되고, +DIF에 의해 촉진되었다. 엽수, 엽면적 및 건물중은 주야간온도가 증가할수록 증가하였는데 야간온도보다는 주간온도의 영향이 컸다. 주간온도차에 대한 엽록소함량의 변화는 주간온도가 낮은 처리구에서 높게 나타났고 T/R비와 SLA는 주간 및 야간온도가 증가할수록 저하되었다. Cucumber (Cucumis sativas L. cv. seolok chungjang) seedlings were grown for 4weeks in controlled environment chamber under 12hrs photoperiodic condition per day with nine different day and night temperature regimes to investigate the possibility of plant height control. Plant heights of seedlings were mainly affected by day temperature rather than night temperature and interaction of day and night temperature. Leaf number, leaf area and total dry weight increased until temperature increase up to 30℃ day and night temperature. The chlorophyll content of leaf from different temperature regimes increased as day temperature decreased and chlorosis phenomenon was appeared in young leaves of -DIF treatments. T/R ratio and SLA(Specific Leaf Area)were negatively proportion to increasing day and night temperature.

Tomato(lycopersicon esculentum MILL. cv. 'Daehyung seogwang') plants were grown in the nutrient solution culture system and were treated with four levels of 0, 20, 40 and 60% defoliation at the first flowering stage. Leaf area and leaf dry weight were decreased as the treatment level increased but there was no significant difference between 0% and 20% defoliation at 60 days after treatment. The effect of defoliation on another vegetative organs as like stem and root was very weaked. And there was no significant difference in fruit yield at the range 0-40% defoliation. The other hand, the plant grown at 60% defolition showed poor fruit production and total dry weight. The result obtained this experiment demonstrated that 40% defoliation is to be suitabilized to control of excessive vegetative growth without the loss of fruit yield.
