基因型和环境对以色列野生二棱大麦籽粒营养品质的影响

Effect of Genotype and Environment on Nutritional Traits of Wild Barley(Hordeum spontaneum)from Israel

为探讨基因型和生长环境对野生二棱大麦营养性状的影响,对源自以色列不同地区的9个群体60个基因型野生二棱大麦材料在3个环境条件下的籽粒可溶性蛋白质、氨基酸、植酸、无机磷和淀粉含量及粒重进行测定,并对检测数据进行了单因素方差分析(One-Way ANOVA)、相关性网络分析(correlation-based network analysis,CNA)和斯皮尔曼秩相关分析(Spearmanp’s Rho Correlation)。结果表明,野生二棱大麦各被测性状与生长地土壤成分存在显著相关性(P<0.01);以色列野生二棱大麦籽粒中无机磷、总淀粉含量和粒重受生长环境和基因型的共同影响,而植酸、可溶性蛋白质、氨基酸含量等性状则主要受生长地环境的影响。

In this study, 60 genotypes of wild barley（Hordeum spontaneum） with nine populations derived from different habitats of Israel were studied for the effect of eco-geographical factors of the origin place and growing environment on nutritional traits under three experimental trials of field. The main nutritional components of nine wild barley populations were measured by single factor variance a- nalysis, correlation network analysis and Spearman Rho significant correlation analysis. The results showed that there is a significant correlation between the multiple nutritional traits of Hordeum spontaneum and the soil composition of tested regions. Meanwhile, the results indicated that genotypes and environments had a collaborative influence on content of inorganic phosphorus, total starch and single grain weight of wild barley, and the difference of environmental conditions was the main factor affecting the phytic acid, soluble protein and amino acid content in grains.
