湖北十堰市核桃优株选择

Analyses on Morphological Traits and Main Nutrients of walnut Fruits in shiyan , Hubei

摘要:

为综合评判湖北省十堰市核桃坚果品质的优劣 , 为十堰核桃育种筛选打下基础 。在野外调查的基础上 , 收集了 12个十堰核桃品种 , 对其坚果外形特征(纵径、横径和侧径) 、单果重以及主要营养成分进行了分析 。结果表明 , 十堰 3 号外 形一致性程度较差 , 十堰 1号的给人们感觉良好 。十堰 10号的平均单果重最大 , 达到 11. 82g;十堰 7 号出仁率最高 , 高达 58. 01% , 与其它十堰核桃的出仁率差异显著;十堰 5号可溶性糖含量最高达到 4. 04%;十堰 3号的可溶性蛋白含量最高达 到 97. 05mg/g;十堰 13号总蛋白含量最高达到 232. 67g/kg;十堰 3号粗脂肪含量最高达到 77. 76% 。根据这些分析结果 , 可以得出初步结论:十堰 3号可以用于核桃油的加工;十堰 7号可以用于核仁加工;十堰 10号可以用于干果生产。

Abstract:

In order to select the best local walnut varieties in shiyan , Hubei province andincreasing the incomes of local walnut producers and improving market completion ability , twelve walnut varieties were collected based on the field investigation in shiyan and their morphological traits and main nutrients were analyzed. These results showed that the single fruit weight of shiy- an No . 10was the greatest (11. 82g) , and shiyan No . 7 had the highest kernel ratio of 58. 01% , and shiyan No . 5 had the highest level of soluble sugars (4. 04%) . shiyan No . 3had the highest content of soluble proteins (97. 05mg/g) , and the highest level of total proteins occurred in shiyan No . 13 (232. 67 g/kg) , and shiyan No . 3 had the greatest content of crude lipids (77. 76%) . It was concluded that the fruits of shiyan No . 3could be used for walnut oil production , and the fruits of shiyan No .7 could be used for kernel production , and the fruits of shiyan No . 10could be sold as nuts .
