果實生長發育與果實品質之改進

Abstract

果實生長之形態，生理及化學變化及其發育模式因果實種類而異，對果實品質之要求亦因而不同。果實本身與環境之變化均影響果實之生長及品質。本文謹就本省果樹果實生長發育與品質相關者試加以探討，並提出問題包括：1.果實發育時醣與有機酸之代謝及控制因素。2.荔枝龍眼果實之發育與退甘及無子果生產之可行性。3.果實水分轉運與果實品質與生理病害之關係。4.套袋對果實品質之影響。 Morpology, physilogy, constituents and growth patterns of fruits are varied with different fruit species. The requirements of quality are also different. The growth and quality of fruit are affected both by fruit itself and environments. Following topics and problems about fruit growth and quality encountering in Taiwan are reviewed and discussed: 1) Sugar and organic acid metabolism and control during fruit development, 2) Fruit development, desweeting, and induction of seedless fruit in litchi and longan 3) water turnover and its effects on fruit quality, and 4) effects of bagging on fruit quality.
