Abstract:

In this study, the correlation between fruit-bearing mother shoots and fruit characteristics of Clausena lansium (wampee) was investigated, so as to provide theoretical basis for establishing scientific cultivation techniques of wampee. Two main wampee varieties (‘Wuhehuangpi’ and ‘Jixinhuangpi’) were used as materials. The characteristics of thickness, length, compound leaf number, leaflet number of the fruit-bearing mother shoots were assessed, and the fruit characteristics such fruit cluster length, fruit cluster weight, total fruit number, single fruit weight, fruit longitudinal diameter, fruit transverse diameter and total soluble solid content were detected, and the correlation between the characteristics of fruit-bearing mother shoots and fruit characteristics was analyzed. The results of correlation analysis showed that thickness, length, compound leaf number, leaflet number of the fruit-bearing mother shoots were all extremely significantly or significantly positive correlated with fruit cluster length, fruit cluster weight, total fruit number, single fruit weight, fruit longitudinal diameter and fruit transverse diameter. According to regression analysis, the fruit-bearing mother shoot thickness was the most important factor to fruit cluster weight. The fruit cluster length, fruit cluster weight, total fruit number, single fruit weight, fruit longitudinal diameter and fruit transverse diameter were gradually increased with the increase of the fruit-bearing mother shoot thickness. The fruit-bearing mother shoot thickness had significant influence on the fruit characteristics of wampee. In actual cultivation management, cultural practices such as proper pruning, fertilization and branch control can be employed to cultivate stout fruit-bearing mother shoot, so as to improve yield and quality of wampee.
