摘　　要：[目的]了解湖北核桃资源的果实生长发育动态。[方法]以宜昌市樟村坪镇的4个核桃实生单株为试材,对其果实的纵径、横径和侧径,果核直径与青皮厚度,果实重量与体积的动态变化进行了连续观测。[结果]随着果实的发育进程,各性状均表现为先上升后保持基本不变的趋势,但各指标达到最大值的时间不一致。果核直径和青皮厚度在7月上中旬达到最大值,果实重量和体积在7月中旬前后达到最大值,而果实的纵径、横径和侧径在6月中下旬前增长迅速。[结论]该研究为果实发育过程中科学合理的管理提供依据。[Objective] The research aimed to understand the growth and development dynamics of walnut seedling resources in Hubei.[Method]We continuously observed the growth dynamic of fruit longitudinal, transverse and lateral diameter of fruit, fruit nucleus diameter and green skin thickness, fruit weight and volume using four walnut seedlings in Zhangcunping Town of Yichang City as experimental materials.[Result]In the process of fruit development, all traiTSshowed a trend of rising first and then maintaining basically unchanged, but the time for each index to reach the maximum was not the same. The nucleus diameter and the green skin thickness reached the maximum in early and middle July, the weight and volume of fruits was around middle July, while the longitudinal,transverse and lateral diameter of the fruit grew rapidly before mid-June.[Conclusion] The research provided a basis for scientific and rational management during fruit development.
