Abstract
In this study, using a split plot design, the corn variety Qiule 151 is selected as material, with four different seed coating agents as the main processing, the set five pharmacopoeia ratio as the auxiliary treatment, on corn seed coating, respectively, to explore the effects of seed coatings in different concentration ratios and pharmacopoeia ratio on seed germination, emergence rate, seedling height, stem diameter, root length, fresh weight, chlorophyll content and the activity of peroxidase. The results shows that the germination rate and germination rate of 14.4% Shuaimiao·thiram suspension seed coating and seed according to the ratio of 1∶50 coating is the best, reached 100%;the seed coating treatment on seedling had great influence, the height, stem diameter, root length and fresh weight ratio of seedling are significantly improved. in appropriate pharmacopoeia ratio (1∶50)treatment. The seed coating had a significant effect on physiological index of seedling. Chlorophyll content decreased than that of the check, but it could promote POD activity.关键词
