砀山酥梨果实发育期间树体矿质元素含量的变化及其相关性分析
Changes and correlations of mineral contents in 'Dangshansu' pear during fruit development
摘要
Abstract
In order to explore the accumulation characteristics of minerals during the development of'Dangshansu'pear fruit,the changes of main mineral elements in fruits,leaves and 1-year-old branches were studied.The results showed that during the fruit development,the contents of N,P,K,Zn,Cu and B decreased,while the contents of Ca,Fe and Mn increased in the leaf.The contents of Mg and S in the leaf showed no remarkable changes.In the one-year-old branch,the contents of N,P,K,Mg,S,Cu,Zn and B decreased,while the contents of Ca and Mn increased.The content of Fe was fluctuant during the fruit development.I the fruit,the contents of N,P,K,Ca,Mg,S,Mn,Cu,Zn and B decreased firstly and then had no remarkable changes and the content of Fe decreased significantly firstly,and then showed a fluctuating change.In the leaf,the contents of N,P,K,Cu,Zn and B showed a positive correlation (P＜0.01),while the Ca content was negatively correlated with the contents of K and B (P＜0.01) and the Mn content was negatively correlated with the contents of N,P and K (P＜0.01).In the one-year-old shoot,the contents of N,P,K,Cu and Zn showed positive correlation (P＜0.05),while the Ca content was negatively correlated with the Fe content (P＜0.01),and the Mn content was negatively correlated with the K content (P＜0.01).In the fruit,the content of Fe and B showed positive correlation (P＜0.05),and the contents of other elements also showed positive correlation (P＜0.01).There were significant positive correlations among N,P,K,Zn and B in the leaf,fruit and one-year-old shoot (P＜0.01).The mineral contents in'Dangshansu'pear were changing during the fruit development;therefore,the fertilization should be conducted based on the change characteristics of mineral elements.关键词
