摘　　要：对来自江西赣州和广东乐昌的21株光皮树优树果实的果肉厚度、鲜果千粒质量、种子千粒质量、果肉含油量、种子含油量、鲜果大小和种子大小等7项数量性状指标进行了研究。结果表明：果实数量性状的变异系数范围为4.35%~23.08%,其中种子大小、鲜果大小、种子含油量、果肉含油量、种子千粒质量、鲜果千粒质量和果肉厚度的变异系数分别为4.35%、6.78%、14.28%、14.39%、17.89%、19.06%和23.08%。果肉厚度与种子千粒质量、鲜果大小与种子大小均呈极显著正相关;种子大小与鲜果千粒质量、鲜果大小和鲜果千粒质量均呈显著正相关。21株光皮树优树果肉中含油量的变异幅度为26.35%~56.88%,种子中含油量的变异幅度为11.77%~19.83%。Fruits from twenty-one selected plus trees of Swida wilsoniana Wanger in Jiangxi and Guangdong provinces were studied.Results showed that variation coefficients of flesh thickness,thousand fruit weight,thousand seed weight,flesh oil content,seed oil content,fruit size and seed size were 4.35%,6.78%,14.28%,14.39%,17.89%,19.06% and 23.08%,respectively,with the range of variation coefficient of 4.35%～23.08%.Significant positive relations between flesh thickness and thousand seed weight,fruit size and seed size,seed size and thousand fruit weight,fruit size and thousand fruit weight were found.Flesh oil content and seed oil content of 21 plus trees were 26.35%～56.88% and 11.77%～19.83%,respectively.
