低盐浸种对高盐胁迫下华山松幼苗生长的影响
Effect of High NaCl Stress on Seedlings Growth of Pinusarmandii Franch.after Low-NaCl Seed Soaking
摘要
Abstract
The effect of high NaCl stress (300 mrnoI/L) on seedlings growth of Pinusarmandii Franch. after seed soaking with low-NaCl concentration (0 — 200 mnol/L) was studied. After seed soaking with 200 mmol/L NaCl,the seed got the best salt resistance. In comparison with the col trol(soaking with water) ,the germination rate and germination energy increased 16. 34 percentage points and 7. 67 percentage points, respectively. Under this condition, the height of seedlings increased 34. 85%, wet weight and dry weight increased 7. 01% and 20. 79%,soluble sugar increased 56. 31%,SOD activity and MDA contents decreased 68. 84% and 40. 6P% ,respectively.关键词
