以红豆为实验材料,研究镧对铜胁迫红豆幼苗生长的影响。结果表明,在2mmoL/L铜剂量胁迫下,加入15mmoL/L镧溶液,对铜胁迫下的红豆幼苗生长有一定缓解效应,可减轻铜对幼苗的伤害程度。
The Phaseolus angularis was used as experimental materials to study the effects of lanthanum on inhibition of plant growth and copper metabolism. The results showed that, under 2mmol/L copper stress treatment, addition of 15mmol/L La3+ could decrease the copper toxicity to the crop seedlings and therefore, reduce the extent of damage to seedlings.
