Abstract

Characteristics of vegetative spur leaf, spur bud, fruiting supr leaf and flowering in relation to canopy position was investigated on order to promote better spur bud and flower bud differentiation on Citrus junos. There was no difference in vegetative spur leaf characteristics among directions. Vegetative spur leaf number and leaf area showed no difference between top and bottom position. There was no difference in spur bud size among directions, but spur bud at top was larger than that at bottom. Specific leaf weight of vegetative spur was mostly influenced by light interception, and leaf dry weight per spur average leaf dry weight, spur bud length and diameter had also a very high correlation with light interception rate. Shading and GA treatment in spur bud and flower bud differentiation was ineffective than natural light. Fruit thinning enhanced fruit quality as well as flower bud differentiation through an increase of leaf number per fruit, over 40 in Citrus junos.

유자(Citrus junos)에 있어서 수관내 위치별 엽, 엽면적, 엽중의 특성차이와 정아의 발생상태, 화아분화와 과실 품질에 미치는 기초자료들을 얻고져 실험을 실시하였던 바 결과는 다음과 같다. 1. 동, 서, 남, 북의 방향별 엽수, 엽면적, 엽중에 있어서는 유의차가 없었다. 2. 수관의 상하간에는 엽수와 엽면적은 유의차가 었었다. 3. 정아의 횡경과 종경은 방향별로는 차이가 없었지만, 상하간에는 유의한 차이를 나타내었다. 4. 투과광도와 엽 및 엽면적과의 상관관계는 광도 감소율에 따라 엽의 엽비중이 가장 큰 영향을 받았으며, 단과지당 전체엽중, 평균 엽중, 단과지 정아의 횡경, 종경도 높은 상과관계를 나타내었다. 5. 화아분화에 차광은 비효과적이었으며, GA처리도 같은 경향을 나타내었다. 6. 적과는 1과당엽수를 40잎 이상으로 하는 것이 화아분화율과 과실의 품질을 향상시킬 수 있었다.
