Effects of Lead Ion on the Mung Bean Seedling Root

摘要

To study the effect of lead ion on the activity of roots of mung bean seedlings, the experiment adopts five kinds of different concentration lead ion to treat with the mung bean seedling, The results show that the higher concentration lead ion treatment resulted in lower activity of mung bean seedlings roots, and lessen protoplasmic surface charge of roots and the rate of electrophoresis migration. It also has a impact on mistosis of the tip of roots, which emerges micronucleus, chromosome lag, chromosome bridge and so on, The study was to provide the theory basis for agriculture environmental protection.
