摘要/Abstract

摘要： 镉是植物生长的非必需元素, 它具有很大的生物毒性, 与其它重金属相比, 更易被植物吸收积累。通过采用营养液水培试验的方法, 研究了外源一氧化氮(Nitric oxide, NO) 对不同浓度Cd2+ (100μmol L^{- 1} , 300μmol L^{- 1} , 500μmol L^{- 1} ) 胁迫下黄瓜幼苗生长、叶片光合特性以及活性氧代谢的影响。结果表明: 300μmolL^{- 1} NO 供体硝普钠(Sodium nitrop russide, SNP) 能显著缓解镉胁迫对黄瓜植株造成的伤害, 对300μmol L^{- 1} Cd²⁺ 处理的黄瓜幼苗缓解效果最好, 可提高幼苗的生长量, 增强幼苗叶片超氧物歧化酶(SOD)、过氧化物
酶(POD) 活性; 提高了叶片叶绿素和脯氨酸(Pro) 含量; 降低了叶片丙二醛(MDA) 含量。

Abstract: Cadmium is a non-essential element for plant growth which has serious biological toxicity and comparing with other heavy metals, Cadmium is more prone to accumulate in plants . The present study was conducted in nutrient solution to investigate the effects of exogenous nitric oxide (NO) on growth of cucumber seedlings , photosynthetic characteristics
and active oxygen metabolism in cucumber leaves under consistently different concentration of Cadmium stress (100 μmol L^{- 1} , 300μmol L ^{- 1} , 500μmol L^{- 1} ) . The results showed that 300μmol L ^{- 1} exogenous sodium nitrop russide (SNP) , a nitric oxide donor , could significantly alleviate the injury to cucumber under Cadmium stress . The treatment of SNP showed
the best results when cucumber under 300μmol L^{- 1} Cd² ⁺ stress , which increased the seedling growth , the activity of SOD, POD, and the content of photosynthetic pigment and proline . Moreover , exogenous nitric oxide markedly decreased the content of MDA under 300μmol L^{- 1} Cd²⁺ stress .

Key words: Cd²⁺ stress
