4个石榴品种发育期叶片主要矿质元素含量动态变化
Dynamic Variation of Main Mineral Element Contents in Leaves of Four Pomegranate Cultivars during Development Period
摘要
Abstract
The mineral element contents of N,P,K,Ca,Mg,Fe,Cu,Zn and Mn in leaves and their correlations were analyzed with four major pomegranate cultivars in China.The results showed that the contents of N,P,Cu and Zn showed the tendency of decreasing at first,ascending later and then decreasing;the K content decreased at first and then increasing;the Ca content increased gradually;the Mg and Mn contents increased at first and then decreased;the Fe content showed the tendency of increasing firstly,then decreased,finally increased.The contents of N,P and Ca were the highest in'Huaibei Hongpitian'leaves;the K,Mg and Zn contents were the highest in'Sichuan Dahongtian'leaves;'Daqingpitian'had the highest contents of Fe and Mn;the Cu content was the highest in'Jingpitian'leaves.The correlation analysis results indicated that there were synergy effects between N,P and K in pomegranate leaves,and Ca,Mg,Fe,Cu,Zn and Mn had different antagonistic effects on N,P and K.关键词
