为了研究碳水化合物有效性对果实生长和脱落的影响，我们通过叶片脱落和茎注入补充蔗糖来产生源库失衡。萨摩柑的御光（柑桔）马克)。部分落叶促进了果实脱落，而蔗糖的补充使柑桔结实率提高了10%以上。同时施用蔗糖可以抵消部分落叶对坐果的影响。从开花到收获连续不断地添加蔗糖，增加了果实中可溶性和不可溶性糖的浓度。我们得出结论，柑橘的果实坐果高度依赖于碳水化合物的有效性。
We generated source-sink imbalances by defoliation and sucrose supplementation by stem injection, to investigate effects of carbohydrate availability on fruitlet growth and abscission in cv. Okitsu of Satsuma mandarins (Citrus unshiu (Mak.) Marc.). Partial defoliation promoted fruitlet abscission, whereas sucrose supplementation increased citrus fruit set by more than 10%. Moreover, when applied together, sucrose supplementation counteracted the effect of partial defoliation on fruit set. When sucrose was supplied continuously from flowering until harvest, it increased the concentrations of soluble and insoluble sugars in fruits. We conclude that fruit set in citrus is highly dependent on carbohydrate availability.
