盐胁迫对贯叶连翘种子萌发及幼苗POD的影响
The Effect of Salt Stress on Seed Germination and Seedling Growth of Hypericum perforatum L.
摘要
Abstract
In order to understand the salt resistance of Hypericum perforatum L., and to prove whether it is suit⁃able for saline alkali soil cultivation, the seed was treated by different concentration NaCl solution or mixed solu⁃tion of same concentration with different salts. The result showed that salt stress inhibited H. perforatum seed germination. The effect of Na2CO3 inhibition was the most significant in all salt treatments. The effect of salt stress on isoenzymes of POD in seeding growth of H. perforatum was analyzed through polyacrylamide gel electro⁃phoresis. The results showed that there exist some differences in the isoenzymatic patterns of POD in different stage. And some differences in the isoenzymatic patterns of POD also occurred in different salt concentrations on the same stage. Therefore, a conclusion was reached that salt stress inhibited H. perforatum seed germination and effect on Peroxidase isoenzyme (POD) activities of the seedling.关键词
