我国核桃砧木选育研究进展

Research Progress of Walnut Rootstock Breeding in China

核桃是我国重要的经济林树种,具有显著的经济效益、社会效益和生态效益。随着我国核桃产业的快速发展,不适砧木造成的嫁接核桃树势弱、商品性低、抗逆性差等不良后果逐渐显现。本文总结了我国核桃砧木品种的培育与筛选,砧木与接穗亲和力,砧木对树势、光合特性和果实品质和产量的影响,砧木的抗逆性等方面的研究进展,以期为核桃砧木的深入研究和生产应用提供参考。

Walnut was an important economic forest tree species in China,which had significant economic,social and ecological benefits.With the rapid development of China's walnut industry,the adverse consequences of the unsuitable rootstocks,such as the weak tree vigor,low commodity and poor resistance were gradually appeared.In this paper,the development of the research on the cultivation and selection of walnut rootstocks,the affinity between rootstocks and scions,the influence of rootstocks on the tree vigor,photosynthetic characteristics,fruit quality and yield,and the stress resistance of rootstocks were summarized,so as to provide reference for the further research and production application of walnut rootstocks.
