摘要/Abstract

摘要： 以‘大鸡心’黄皮[Clausena lansium(Lour.)Skeels‘Dajixin']为材料，研究了不同程度疏果对果实发育、着色、产量及树体不同器官碳水化合物含量的影响。结果表明：疏果减少了树体产量，但促进了果实的发育，花后95 d（采收）时，疏果50%和25%处理的果实鲜样质量分别比对照果增加了33.7%和13.9%，疏果有利于果实的着色，同时提高了叶片、1cm粗枝条、结果母枝及果实的总碳水化合物含量。此外，疏果有利于采果后新梢生长，显著增加新梢的长度和粗度。

关键词: 黄皮, 疏果, 果实发育, 着色, 碳水化合物

Abstract: The wampee (Clausena lansium (Lour.) Skeels) cultivar 'Dajixin' was used to study the effects of two levels, ie, 50% and25%, fruit-thinning on fruits development, pigmentation and carbohydrate content in plant organs, and non-thinning as control. The main results were as follows. The yields of 50% and 25% fruit-thinning treatment in this trail were decreased in a certain degree, compared with control. But fruit-thinning promoted the development of wampee fruits. At harvest (95 days after anthesis), compared with control, the fresh mass of individual fruit with 50% and 25% fruit-thinning increased by 33.7% and 13.9%, respectively. Fruit-thinning was helpful to the pigmentation of wampee fruits, and increased the total content of carbohydrate in plant organs such as leaves, 1-cm-size stems, fructiferous stems and fruits. In addition, compared with control, fruit-thinning promoted the growth of shoots after harvest, and increased their lengths and diameters significantly.

Key words: wampee, fruit-thinning, fruit development, pigmentation, carbohydrate
