摘要 以1年生枳壳砧和枳橙砧纽荷尔脐橙幼苗为材料,采用砂培方法研究不同氯离子浓度处理下对2种脐橙幼苗的生长和体内氯离子含量的影响。结果表明,不同砧木纽荷尔脐橙对氯离子的耐受力存在差异,枳壳砧较枳橙砧耐受力差;植株体内氯离子含量在不同砧穗组合间存在差异,枳壳砧脐橙叶片中氯离子的含量明显高于根系,而枳橙砧总体呈现与之相反的变化趋势。两种砧木纽荷尔脐橙对氯离子的敏感性差异可能与氯离子在根系和叶片中的分配差异密切相关。 One year old Poncirus Trifoliata rootstock and Citrange rootstock of Newhall navel orange seedlings were used as materials, and the date including the growth of citrus scion-rootstock combination and chloride ion in vivo distribution were researched through sand cultivation. The results has indicated that there was difference performance for different citrus scionrootstock combination under treatments with different chloride ion levels, and the tolerant capability of chloride for Citrange rootstock was higher than Poncirus Trifoliata rootstock. There was higher chloride concentration in roots than leaves for Poncirus Trifoliata rootstock under different chloride iron levels in this trial. However, opposite performance for Citrange rootstock in the same condition. The different tolerant capability for chloride ion stress between the two kinds of citrus scion-rootstock combination maybe closely related to the chloride iron distribute between the root system and leaves.
