| 摘 要： | 对不同小麦品种植酸 (PA)含量和蛋白质含量及相关性状的相关分析结果表明 :植酸含量与株高呈极显著正相关 ,与产量呈显著负相关 ,与蛋白含量呈正相关但不显著。经通径分析发现 ,穗长、穗粒重对植酸产量直接作用都达到负的显著水平 ,千粒重、穗粒数对植酸产量直接作用达到显著正相关。植酸产量、籽粒产量对植酸含量直接作用分别达到正的极显著水平和负的极显著水平。

| Abstract: | Analysis on contents of Phytic acid and protein and its relative characters in the seeds of different wheat varieties shows that there is a significant correlation between Phytic acid content and plant height, but a negative significant correlation between Phytic acid content and yield. Path analysis shows that Phytic acid yield has significantly negative correlation with spike length and weight per spike,but significantly positive correlation with grains per spike and 1000-grain weight.Phytic acid content correlates very positively with Phytic acid yield and very negatively with grain yield,respectively. |
