| 摘 要： | 以甘蔗品种新台糖22号(ROC22)为供试材料,叶面喷施不同浓度(50mg/L、100mg/L、200mg/L)壳聚糖,干旱处理后观察甘蔗叶片叶绿素含量、脯氨酸含量、可溶性蛋白含量以及过氧化物酶活性等抗旱生理指标的变化,研究壳聚糖对甘蔗苗期抗旱性的影响。结果表明,壳聚糖具有提高甘蔗抗旱性的作用,其中100mg/L壳聚糖处理可以明显提高叶片的叶绿素含量,增加脯氨酸和可溶性蛋白含量,提高其过氧化物酶活性,从而增强甘蔗的抗旱能力。

| Abstract: | In order to study the effect chitosan with different concentration on drought resistance of sugarcane,ROC 22 was sprayed with three concentration(50mg/L,100mg/L,200mg/L)of chitosan,under drought stress condition.The changes of some physiological indexes including the content of chlorophyll,proline,soluable protein and the activity of peroxidase in ROC 22 were determined.The results showed that the treatment of 100mg/L chitosan increased the content of chlorophyll,proline,soluable protein and the activity of peroxidase,which indicates chitosan can improve the drought-resistant ability of sugarcane under drought stress. |
