摘　　要：对光皮树果实纵径、横径进行定期田间测定,同时对果实鲜重和干重进行定期测定,绘制生长曲线,结果表明光皮树果实生长发育过程可分为3个时期:幼果缓慢生长期,果实缓慢生长期,果实熟前迅速生长期。果实含水率一直在下降,而含油率则一直在增长,达到最大含油率34.23%后趋于稳定。Swida wilsoniana fruit longitudinal diameter, width regularly were measured in the field, while the fruit fresh weight and dry weight measured regularly. The growth curve results showed that growth of Swida wilsoniana fruit process can be divided into three periods： The slow growing young fruit, fruit is slow growing, fruit growing rapidly riped before. Fruit moisture content has been declining, but the rate has been increasing in oil, the oil tends to be stable after the maximum rate of 34.23%.
