摘  要:
以甜瓜品种"白沙蜜"的种子为试材,用不同浓度的阿司匹林(Asp)水溶液在室温下浸种24h,研究了Asp对低温胁迫下甜瓜幼苗生理特性的影响。结果表明:低温胁迫下,经Asp浸种的甜瓜幼苗生长良好,其中以150mg/L的Asp处理效果较好,可显著提高叶片保护酶活性、可溶性糖含量;显著降低叶片电解质渗出率,增强了甜瓜幼苗对低温胁迫逆境的抵抗能力,减轻和缓解了低温伤害。

摘  要:
Taking the muskmelon(cv.Baishami)seeds as the material,which soaked 24 hours with different concentrations of Asp under the room temperature,the effects of Asp on the seedlings' physiological characteristics under the chilling stress were studied.The results showed that the muskmelon seedlings grown from seeds soaking in aqueous solutions(60~2 000 mg/L)of Asp displayed enhanced tolerance to chilling stress,the effect of 150 mg/L Asp was the best,which obviously enhanced the leaf blade antioxidant enzymes activities,and the soluble sugar content;obviously reduced the rate of electrolyte leaching,strengthened the resistance of the melon seedlings to the chilling stress,decreased and alleviated the effects of chilling injury.
