低磷胁迫对玉米产能营养成分和矿物质元素的影响
Effect of low phosphorus stress on energy-yielding nutrients and minerals of maize
摘要
Abstract
To clarify the effect of low phosphorus stress on the nutritional quality of maize and to screen for maize varieties that are tolerant to low phosphorus and of high quality,this study measured and analyzed the changes in the contents of starch,crude protein,crude fat,the ratio of amylose to amylopectin(AM/AP),and the contents of minerals such as P,K,Zn,and Ca in the grains of 14 maize genotypes under low phosphorus(LP)and normal phosphorus(NP)field treatments.The results showed that:1)Compared with NP,LP significantly reduced the AM/AP,the contents of P and K in maize grains,but significantly(P＜0.05)increased the content of crude fat;2)Based on the relative change rate of each nutrient composition under low phosphorus conditions,the 14 maize genotypes could be classified into three categories:those with increased contents of most nutrient composition,those with decreased contents of most nutrient composition,and those with small changes in most nutrient components under low phosphorus conditions like'C783','E62','D519','A61','E54',deserve further breeding;3)Two-way ANOVA showed that genotype(G),phosphorus treatment(PT),and their interaction(PT×G)significantly affected the contents of starch,amylose-to-amylopectin ratio,crude protein,crude fat,P,K,Ca,and Cu.This study provides a material basis and theoretical reference for breeding of maize varieties that are tolerant to low phosphorus.关键词
