Mechanisms of differential tolerance of crop plants to high aluminium and low phosphorus growth conditions

摘要: Aluminium (Al) toxicity and phosphorus (P) deficiency often appear together in acid soils. The mechanisms of differential tolerance crop plants to high Al low P were investigated under solution culture field conditions. the conditions was order lupin (Lupinus aldus L.) > soybean (Glycine max Merr.) ≫ rape (Brassiaca napus var.) ≒ tomato (Lycopersicon esculentum Mill.) culture, field. found be higher than culture. In contrast, similar mechanism soil that considered caused mainly by Al. On other hand, condition secretion phosphatase organic acids roots condition.
