水稻硒锌铁元素对两因子互作的响应
Response of Selenium,Zinc and Iron to Interaction of Two Factors in Rice
摘要
Abstract
To find out the enrichment characteristics of functional elements of selenium,zinc and iron in rice,which have great influence on human health,and promote the development of functional agriculture,the leaf surface application of selenium(A1,A2,A3,A4 and A5)was carried out on the leading hybrid high quality rice'Yexiang Youbasi'(B1)and conventional high quality rice'Baixiang 139'(B2)by split zone design.The results showed that the experimental treatment significantly increased the selenium content of rice and rice straw.The average selenium content of B2 rice was significantly higher than that of B1 by 17.2%.There was no significant difference in the average selenium content of rice straw between B1 and B2.B1 rice had a stronger tolerance to high exogenous selenium stress than B2,and B2 rice straw had a stronger tolerance to high exogenous selenium stress than B1.The interaction effect of A4×B2 and A4×B1(applied 1.5 times selenium)on the difference in selenium content between B1 and B2 rice was extremely significant.A1×B1 and A1×B2(without selenium application)had no significant effect on the difference in selenium content between B1 and B2 rice,indicating that exogenous selenium had an impact on the difference in selenium enrichment between rice varieties(combinations).Foliar application of selenium had no significant effect on the zinc and iron content of rice,but increased the difference in zinc enrichment between B1 and B2 rice and reduced the difference in iron enrichment between B1 and B2 rice.This suggested that exogenous selenium also had an impact on the differences in zinc and iron enrichment between rice varieties(combinations).B1 rice had significantly stronger zinc enrichment than B2 rice,while B1 and B2 rice had comparable iron enrichment.Exogenous selenium had different effects on the enrichment of selenium,zinc and iron in rice,and also affected the difference in the enrichment ability of selenium,zinc and iron among rice varieties.It was worth paying attention to the evaluation and screening of rice varieties(combinations)rich in selenium,zinc and iron.关键词
