Study on Effect of Cr~(3+)、Zn~(2+)、Pb~(2+) on Seed Germination and Seedling Growth of Wheat

An experimental study was made to explore effects of different mass concentration Cr3+、Zn2+、Pb2+ on the seed germination and seedling growth of wheat.The results showed that soaking the wheat seeds with a thick Cr3+ solution(0.10%) has the obvious inhibitory action on the germination rate;Lower 0.05% Zn2+ has the certain promoter action,while the large density has the slight inhibitory action to wheat's growth;Lower 0.10% Pb2+ has the certain promoter action,but the large density has the slight inhibitory action to wheat's growth;Seedling's growth can manifest the influence of Pb2+ than the seed germination.
