Abstract:
      Tow pumpkin cultivars, Feicui 2 (salt tolerant) and Xinzaoqing 1 (salt sensitive) were employed to study the effect of ALA on some physical characteristics and yield of pumpkin under the stress resulted from 200 mmol/L, 400 mmol/L NaCl. The results showed that under 200 mmol/L NaCl stress, the alleviate role of ALA on the salt sensitive species' growth and physiological characteristics is quite good, and under 400 mmol/L NaCl stress, the alleviate role of ALA on the salt-tolerant Feicui 2 is much more obvious. ALA could increase chlorophyll, soluble protein and proline content, reduce Permeability of cell and MDA content remarkably, and increase the ability of pumpkin to resist salt, at last improve production under salt stress.
