Abstract

The treatment of growing tomato (Lycopersicum esculentum) plants with CdCl2 (0, 1, 5, 10, 25 et 50 microM) on various plant physiological parameters and membrane lipids of primary and young leaves was studied. In leaves of tomato plants Cd produced a significant inhibition of growth, chlorophyll content and alteration of the nutrient status in both primary and young leaves. A decrease in lipid contents, specially galactolipids and phospholipids, was observed after Cd treatment.

摘要

研究了用氯化镉（0、1、5、10、25和50微摩尔）处理生长中的番茄（番茄）植株对各种植物生理参数以及初生叶和幼叶膜脂的影响。在番茄植株的叶片中，镉显著抑制了生长、叶绿素含量，并改变了初生叶和幼叶的营养状况。镉处理后观察到脂质含量下降，特别是半乳糖脂和磷脂。
