Abstract:
The number of secondary shoot is seen not only as the basis of the increasing expansion of crown and the improvement of yield but also as the key biological characteristics differing early-fruiting walnut from late-fruiting walnut.The number of the primary and secondary branches of 15 kinds of 2-year-old walnut seedlings were investigated and analyzed.The results showed that there exist the obvious differences among the branches of 15 different varieties.‘Chandler’,’Xifu No.1’ and ‘Liaohe No.3’ were featured by freely branching，the number significantly higher than the average，early fruiting and higher yield .Meanwhile，it showed that the number of the failures of annual shoot was the vital index of walnut’s resistance to coldness and there existed apparent differences in the resistance to coldness of different varieties.‘Lipin No.1’,’Liaohe No.3’，together with ‘Xilin No.3’ had the better resistance to coldness while both ‘Xifu No.2’ and Chandler had the poor resistance.
