【摘要】 本研究探讨了嫁接在不同矮化中间砧上红星苹果发育枝和结果枝内矿质元素在春季期间的变化动态。经统计学分析表明,不同枝内各矿质元素含量均呈显著的消长关系;各元素含量在此期间基本具有一定的消长特点;不同中间砧及枝内矿质元素含量的变化规律颇为一致。试验结果分析证明,红星苹果发育枝与结果枝内的矿质元素含量具有一定的相关性。更多还原

【Abstract】 The present study delt with the spring variation of the mineral ele- ments in the shoots and friut branches of starking apples on dwarfing inter- stem.Statistical analysis showed significant differences from March to May in the amounts of N,P,K,Ca,Mg,Fe,Mn,Cu,Zn,and Na in the different branches.The variation curves representing the contents of mineral elements in the branches basically possessed a special change character.Moreover,the variation of the branch in elements contents demonstrated a similar tendency between the two interstems.This study through analysis has shown that there is a correlation between the contents of mineral elements of shoots and friut branches in starking apple trees on dwarfing interstem.更多还原
