Abstract:

The paper investigated and evaluated the nut qualities of 13 walnut cultivars of Fenyang in Shanxi province, and the mineral nutrition content of their nutmeats were determined. The results showed that the nut qualities of different walnut cultivars differentiates each another, and that of ‘Zhonglin No.5’, ‘Luguang’, ‘Jing746’ and ‘Jinlong No.2’ are better. The crude fat content of ‘Zhonglin No.1’and ‘Zhonglin No.2’, ‘Liaohe No.1’, ‘Wen185’ and ‘Jinlong No.2’ are all relatively higher and over 65% and reach the super standard of nation. The crude protein content of 13 types of walnut all exceed super standard of nation, and that of ‘Zhonglin No.3’, ‘Zhonglin No.5’, ‘Zhonglin No.6’, ‘Jing746’ and ‘Jinlong No.2’ exceed 20%. The mineral nutrient contents of different kinds of walnut cultivars are different, Ca、Fe and Mn of which are bigger and P、K、Mg、Zn and Cu are relatively smaller.
