| 摘 要： | 以农大108为材料,研究外源亚精胺浸种对玉米幼苗生长和生理特性的影响。结果表明,外源亚精胺能减少芽涝逆境下玉米幼苗黄叶数和死苗率,延缓叶绿素含量的下降,维持根细胞膜透性的稳定,减少芽涝逆境下超氧阴离子(O2-).产生速率和丙二醛(MDA)的积累。外源亚精胺浸种能提高玉米的抗芽涝能力,适宜浓度为0.4mmol/L。

| Abstract: | Nongda108 was soaked with exogenous spermidine. Effects of exogenous spermidine on the growth and physiological characteristics of maize seedlings under water logging stress were studied. The results indicated that exogenous spermidine could reduce the yellow leaves per plant and the death rate of maize seedlings under water logging stress; retard the descent of chlorophyll content; maintain the stability of plasmalemma permeability; decrease the production rate of O2-.. and the accumulation of MDA of maize seedlings under water logging stress. The ability of anti-water logging stress of maize seedlings was increased by soaking with exogenous spermidine. The optimal concentration of spermidine was 0.4 mmol/L. |
