摘要
在盐胁迫下,采用盆栽方法研究AM真菌对红花植株耐盐生理指标的影响,以不接种为对照。结果表明,在0、0.1%和0.2%浓度NaCl胁迫下,AM真菌促进红花幼苗的生长,接种真菌的红花叶片SOD和CAT活性、脯氨酸和可溶性蛋白的含量都高于不接种处理的,叶片细胞质膜透性和MDA含量则低于不接种处理的,结果证明AM真菌可以提高植物的耐盐性。
The effect of inoculation of arbuscular mycorrhizal fungi on the physiological indicators of salt tolerance in safflower （Carthamus tinctorius） plants was investigated under salt stress. In this experiment, safflower plants were grown in pots with three concentrations of NaCl （0, 0.1%, and 0.2%）, and the safflower not inoculated with fungi was used as control. The results showed that AM fungi promoted seedling growth of safflower. The activities of SOD and CAT, the contents of proline and soluble protein in safflower leaves inoculated with fungi were all higher than those in control. And the plasm membrane permeability and MDA content in safflower inoculated with fungi were lower than those in control. Those results suggested that AM fungi could improve salt tolerance of safflower plant.
