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
