| 摘 要： | 以荔枝为试验材料,研究了低温胁迫条件下喷施壳聚糖和水杨酸对荔枝生理生化的影响。结果表明,适当浓度的壳聚糖和水杨酸处理能有效减轻荔枝的低温伤害,与清水对照相比,荔枝叶片叶绿素、脯氨酸、可溶性蛋白的含量明显提高,保护酶的活性也明显增加,MDA的积累减少。说明壳聚糖和水杨酸处理能够明显提高荔枝的抗寒性,其中,以1000mg/L的壳聚糖和50mg/L的水杨酸复配后效果最佳。

| Abstract: | This paper focused on the effect of spraying chitosan and salicylic acid to Litchi under low temperature stress conditions.The physiology and biochemistry of litchi were studied as well.Results showed that the appropriate concentration of chitosan and salicylic acid treatment could effectively reduce injury caused by low temperature to litchi,compared with water control,chlorophyll,proline,soluble protein content of litchi after treatment and the activity of protective enzyme increasing significantly.However,the accumulation of resistance could significantly be improved.Furthermore,when 1 000 mg/L chitosan combined with 50 mg/L salicylic acid,the litchi acquired the best cold resistance capability. |
