| 中文摘要: |
| 以2个耐盐性不同的西葫芦品种翡翠二号（耐盐性较强）和新早青一代（耐盐性较弱）为材料，研究了叶面喷布5-氨基乙酰丙酸（ALA）对200 mmol/L，400 mmol/L NaCl胁迫下西葫芦生长某些生理特性及果实产量的影响。结果表明，外源ALA对200 mmol/L NaCl胁迫下盐敏感品种的生长及生理特性的缓解作用较好，而在400 mmol/L NaCl胁迫下ALA对耐盐性较强的翡翠二号的缓解作用显著。ALA处理可提高NaCl胁迫下西葫芦叶片的叶绿素、可溶性蛋白及脯氨酸含量，降低细胞膜透性，抑制MDA产生，增加西葫芦植株对盐胁迫的抵抗能力，显著提高盐胁迫下西葫芦产量。 |
| 英文摘要: |
| 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. |
