Abstract

Abstract: The study shows that seed soaking with HgCl₂ can decrease the germination rate of maize, inhibit the growth and respiration intensity of its seedling, and the activities of aminotransferase, diastase and lipase in endosperm and those of diastase and lipase in seedling during the process of germination. Low concentration of HgCl₂ can promote maize growth.
