摘要
以‘大鸡心’黄皮为材料,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,但促进了果实发育,花后95d(采收)时,疏果50%和25%处理的果实鲜样质量分别比对照增加了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。
The wampee [Clausena lansium(Lour.)Skeels] cultivar 'Dajixin' was used to study the effects of two levels,ie,50% and 25% fruit-thinning on fruits development,pigmentation and carbohydrate content in plant organs,and non-thinning as control.The yields of 50% and 25% fruit-thinning treatment in this trail were decreased 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.
