摘　　要：以‘妃子笑’荔枝(Litchi chinensis Sonn.cv.‘Feizixiao’)果皮为试验材料,探讨果皮K、Ca和Mg含量的变化特点及其与着色的关系,结果如下。全K含量呈下降趋势;全Ca含量呈上升趋势;全Mg含量变化不显著;同期全K、Ca和Mg含量呈显著递减趋势;水溶性K含量在前期无显著变化,后期呈"下降—上升—下降"变化;水溶性Ca含量在采前一周出现低谷而其余时间无显著变化;水溶性Mg含量呈上升趋势;同期的水溶性K、Mg和Ca含量呈显著递减趋势;全Ca含量较高是促进果皮转红的关键因素;花色素苷和叶绿素含量均与水溶性Mg和全Ca含量的一元指数函数回归方程均显著相关,且前者呈正相关、后者呈负相关。The content change characteristics of K,Ca and Mg in the pericarp of ‘Feizixiao’litchi and their relation to pericarp’s coloring were studied. The results showed that the content of the total K tended to drop. The content of the total Ca tended to rise. The content of the total Mg changed insignificantly. The contents of the total K,Ca and Mg significantly decreased in sequence. The content of the water-soluble K changed insignificantly during the earlier period,then it changed by the curve ＂droprise-drop＂. The content of the water-soluble Ca dropped to the bottom on one week before harvest,and then it changed insignificantly. The content of the water-soluble Mg rose. Meantime,the contents of the water-soluble K,Mg and Ca significantly decreased in sequence. The higher content of total Ca was the key factor to improve the pericarp’s reddening. The anthocyanin and chlorophyll contents were significantly relative to the univariate exponential regression equations of the contents of the water-soluble Mg and the total Ca,and the former was positive relative,and the latter was negative relative.
