The Inlfuence of Different Triggering Dehydration Treatment on the Corn Seed Germination
To study the effect of priming and drying treatment on corn seed germination, number 2 waxy corn seeds are treated with NaCl solution KNO3 solution, H2O2 and PEG of different concentrations, respectively and are placed in constant temperature incubator to germinate. Germination rate, germination potential and the content of soluble sugar, soluble protein, malondialdehyde (MDA) and catalase (CAT) in physiology stage are measured. The results show that the 0.50%NaCl and 0.75%H2O2 lead to relatively high germination rate and the seeds treated with15% PEG contains higher content of soluble sugar, soluble protein, catalase activity compared with other treatment. Compared with the seeds treated with water dehydration, the seeds treated with triggering dehydration contain less MDA, which shows dehydration treatment can improve the germination rate to a certain extent and affect contents of some physiological substances in seeds.
