- 摘要:
- 外源激素处理野生大豆可以提其抗盐性。用0.6% NaCl处理野生大豆幼苗后,再用植物激素(NAA,6-BA,GA)配制相同浓度的溶液处理幼苗,通过对比测定幼苗的叶绿素、过氧化物酶、丙二醛等各项生理生化指标,研究不同激素对野生大豆幼苗盐伤害及抗盐力的影响。结果表明,一定浓度的激素处理可以促进盐胁迫下野生大豆幼苗的生长,提高叶绿素的含量,增强保护酶的活性,降低丙二醛含量,增强幼苗对盐渍环境的抵抗能力,缓解盐害。
- Abstract:
- Wild soybean (Glycine soja Siebold & Zucc.) tends to increase their salt tolerance when treated by exogenous phytohormones.The wild soybean seedlings,treaded with Naphthalene acetic acid (NAA),N6-benzyl adenine (6-BA) and Gibberellic acid(GA),were grown under salt stress of 0.6%NaCl.Then the physiological and biochemical indexes such as peroxidase (POD)activity,malondiadehyde(MDA) content and chlorophyll content were determined.So as to investigate the effect of exogenous phytohormones on cell membrane injury and salt tolerance capacity of wild soybean seedlings.The results proved that exogenous phytohormones could increase POD activity and chlorophyll content,decrease MDA content.Therefore,exogenous phytohormones could strengthen salt tolerance of wild soybean and the salt injury was alleviated.
