  • This study was conducted to provide basic information to breeders and agronomists working with sesame. Grain filling rate were investigated for eight plant types classified by branching habit, capsules per axil, carpels and loculi of a capsule. Two typical cultivars were chosen for plant type among 527 gene pools. Grain filling rate didn't increase with little difference between lower and middle part capsules, Jut significantly decreased in upper part. Grain filling rate of lower part, main stem and center capsules appeared higher than that of upper part, branch and side capsule for grain filling. Mono-capsule setting and unbranched plant type were higher for grain filling than tricapsule setting and branched type due to inactive ripenness on branched capsule. NMB type showed that best maturity and relatively good grain filling in BTB type despite it's largest sink capacity. NTQ and BTQ type appeared poor ripenness because of immaturity of higher part side capsules; however it was believed that there were still possibilities for improving ripenness in 3 capsule and 4 carpels 8 loculi type by the good maturity of 1 capsule and 4 carpels 8 loculi type.

  • This study was conducted to investigate the dry matter production and distribution ratio of dry matter produced for each of 5 botanical types (Virginia-Small Seed, Virginia-Large Seed, Spanish, Valencia, Shinpung) of Peanut (Arachis hypogaea L.) in Peanut culture limiting region. The total dry weight increased in order of Virginia-Large seed, Virginia- Small Seed, Shinpung, Spanish, Valencia type. The maximum Crop growth rates (Cmax) were Virginia-Small seed 18.22-23.41 g/㎡/day, Virginia-Large seed 19.61-20.03 g/㎡/day, Shinpung 16.33-19.77 g/㎡/day, Spanish 13.86-16.28 g/㎡/day, Valencia 13.97-16.25g/㎡/day, respectively. LAI showed the high value at vinyl-mulching than non-mulching. In the early filling stage, distribution ratio of dry matter produced showed the highest at the shinpung type than the other types.

  • 최근 들어 토마토를 교육용 소재로 이용하거나 가정에서 재배하고 싶어 하는 사람들이 많아지고 있다. 그러나 기존에 개발된 품종들은 대부분 줄기가 무한정으로 자라면서 열매가 달리는 무한형 품종으로 가정이나 학교 교실에서 재해하기에는 관리상 어려움이 많다. 국립원예특작과학원에서는 좀 더 작고 쉽게 누구나 재배할 수 있도록 초형을 유한형의 왜성으로 개량하고 관상용 가치도 있으면서 식용으로 이용할 수 있는 토마토를 개발하였다.

  • Ethylene evolution of leaves was measured in the samples of barley and wheat grown in the various conditions and treatments. The older and stepped leaf of barley had tended to the tendency to contain more ethylene than the younger and sound leaf. Relatively high concentration of ethylene was evolved in the samples which the detecting time was delayed and so was in the samples incubated at high temperature. The higher evolution of ethylene was determined by the barley plant grown in the field and with compost application compared to the samples grown in the pot and with composite fertilizer application, however the flooding treatment resulted in decreasing ethylene evolution comparing to untreated barley and wheat. The prostrate type and higher chrolophyll content leaves of wheat appeared to produce more ethylene than erect and lower chrolophyll leaves did.
