Diversity analysis on biochemical components of walnut germplasms in northwest Tarim Basin
摘要
Abstract
Forty?four walnut resources were collected from the northwestern margin of the Tarim Basin in Xinjiang,of which forty?one are 50 years old and three main varieties.The main biochemical components of protein,sugar,fat,amino acids, oleic acid,linoleic acid,linolenic acid,palmic acid,octadecoic acid were analyzed.The results showed that the biochemi?cal composition of 44 resources varied greatly,and there were abundant diversities.The variation of sugar and other nine in?dexes ranged from 4.93%to 30.93%,Shannon?Wiener index(H′)was 1.38-2.02. The variation range of seventeen amino acids ranged from 10.07%to 35.71%,Shannon?Wiener index(H′)was 1.85-2.20. The principal component analysis on main biochemical components showed that the accumulative contribution rate of three main components of protein,sugar and fat was 81.67%.Cluster analysis showed that there were significant differences in the biochemical components among the groups,and the clustering of the groups was closely related to the geographical distribution,and the proportion of biochemi?cal components in the same resources in the basin was similar. Compared with the main varieties,the real resources have higher variability in sugar,protein,fat and other aspects,and have certain potential for development.关键词
