摘 要:美国黑核桃被引进我国已近30年,普遍进入盛果期。在引进的品种中选取7个样品进行复叶与果实性状规律分析,其中东部黑核桃3个样品、魁核桃3个样品、小黑核桃1个样品。结果表明:复叶与果实大小呈显著正相关,复叶与果实性状的聚类分析也把3个种区分开来。在黑核桃品种选育工作中,可以参考复叶特征对不同果实需求进行选优,在结果期前初步筛选,节约成本、提高效率。American black walnut has been introduced to China for nearly 30 years,and it has generally entered the period of fruit flourishing.Among the introduced varieties,7 samples were selected for analysis of compound leaf and fruit characteristics,including 3 samples from Juglans nigra,3 samples from Juglans major and 1 sample from Juglans.microcarpa.The results showed that the size of the compound leaf has a significant positive correlation with the size of the fruit,and the cluster analysis of the characters of the compound leaves and the fruit also distinguishes the 3 species.In the selection of black walnut varieties,we can select different fruit needs according to the characteristics of compound leaves,and select before the fruiting stage to save cost and increase efficiency.
