摘要：以菊花‘夏黄’扦插苗为试材,研究了自然干旱条件下,叶面喷施茉莉酸甲酯（M J）对菊花扦插苗抗旱相关生理指标的影响。结果表明：与对照相比,1 mg.L-1M J处理使菊花扦插苗叶片含水量升高,叶绿素含量在处理8~12 d显著增加,丙二醛（MDA）含量降低;处理第12天,脯氨酸含量显著高于对照,达2.7 mg.L-1,超氧化物歧化酶（SOD）、过氧化物酶（POD）活性分别比对照高29.6%和70.5%。各处理相比,在生根扦插苗移植前4~8 d,喷施1mg.L-1M J提高菊花扦插苗抗旱性的效果最佳。
To investigate the effect of exogenous Methyl Jasmonate（MJ） on drought-resistance of Chrysanthemum Cuttage ＇xia huang＇,the main drought-resistance physiological indexes were studied under natural drought stress.The results are as follows： Compared to the control,1 mg·L-1 MJ could increase the water content of leaves and reduce the MDA content,the chlorophyll content increased significantly with 8-12 days treatment.At 12 days treatment,the proline content increased significantly,and reached 2.7 mg·L-1,the SOD,POD enzyme activity were 29.6% and 70.5% higher than that of the control.Over all,Spraying 1 mg·L-1 MJ 4-8 days before transplanting was the best for the drought resistance of Chrysanthemum cottage.
