Abstract:
The biological characters and nutritional components of five introduced varieties of early-fruiting walnut in Shaanxi were studied in the paper. Fruit characters and nutritional composition of early-fruiting walnut from the introduced area and the original area were determined compared with local late-maturing walnut in Shaanxi and other oil nuts. The results showed that the main nutritional components of five introduced varieties of early-fruiting walnut in Shaanxi were all higher than the almond, hazelnut and cashew. The early-fruiting walnut from the introduced area had the same biological characters as that from the original area. Their fruit characters were well and the high yield period was improved above five years. The main nutritional ingredients of early-fruiting walnut indicated no significant difference(P＞0.05) compared with the local late-maturing walnut in Shaanxi province.By comprehensive analysis, Lantian and Zhouzhi county were the most suitable ecological cultivation areas for early-fruiting walnut, Huanglong and Yijun county were the more suitable ecological cultivation areas.
