微量元素对大豆异黄酮含量和产量构成性状的影响及其相关分析

通过对3个品种施用微量元素,测定其对大豆籽粒异黄酮含量及对产量构成性状的影响,分析了对产量构成性状与异黄酮含量的相关性.结果表明,不同品种间异黄酮含量差异显著,同一品种不同处理间差异不显著.微量元素的配合使用效果在3个品种上均比对照好;在产量构成性状方面,绥农10、绥农14的株高普遍降低,而施用B、Zn、Mo及配施使合丰43增高大于5%;单株结荚数:绥农10和绥农14增加较明显;百粒重:绥农10增加较明显;单株重:三个品种均有不同程度的增加,但绥农14经方差分析差异达到5%显著.相关性分析表明三个品种,不同产量性状均与异黄酮含量无显著的正相关,且多数呈现负相关.

EFFECT OF TRACE ELEMENTS ON THE SOYBEAN ISOFLAVONES CONTENT AND THE PROPERTIVE TO THE YEILD AND CORRELATION ANALYSIS BETWEEN THEM

We applied trace elements to three different soybean varieties,then determined its effect on soybean isoflavones content and on the properties relative to the yield,at last,we analysed the correlation between them,the result showed to the isoflavones content: the effect of the cooperation of different traces elements was better than that of the blank treatment in some degree,but it was not significant,there were significant difference among different varieties;to the yield: the height of Suinong 10 and Suinong 14 decresed generally,the height of Hefeng 43 increased about 5 percent by applying B,Zn,Mo and the mixture of trace elements,yet others decreased;the number of the pod per soybean increased obviously in Suinong10 and Suinong14;the weight of 100-seed of Suinong10 increased obviously;the plant weight of the three varieties increased in some way,but only Suinong14 arrived 5 %singnificamce by analysis ofvariance.By correlation analysis;inthe three varieties,there was no significant direct correlation betweenthe properties relative to the yield and the isoflavones content,moreover,majority of themshowed nega-tive correlation,its correlation degree varied fromdifferent varieties.
