研究了缺Zn溶液培养对番茄(Lycopersicon esculentum miller)和甜椒(Capsicum frutescens L. Var. grossum Bailey)生长发育及P、K、Ca、Zn在植物体内各部位含量的影响。结果表明,2种蔬菜叶部缺Zn症状与叶含Zn量关系不大,而与叶含P、Ca量密切相关,叶部缺Zn症状主要是由于叶内P过度积累产生的毒害作用和叶含Ca量大幅度降低产生的有害影响及K含量降低造成离子平衡失调。
The effects of Zn deficient culture on the growth and development and the contents of P, K, Ca and Zn in tomato (Lycopersicon esculentum miller) and pepper (Capsicum frutescens L. var. Grossum Bailey) were studied. The results showed that there was no significant relationship between Zn deficiency and leaf Zn content in leaves of two kinds of vegetables, but closely related to leaf P and Ca content. The symptoms of Zn deficiency in leaves were mainly caused by excessive accumulation of P in leaves and leaf The deleterious effects of a significant reduction of Ca and the reduction of K cause ion imbalances.
