| 摘 要： | 以小白菜(Brassica campestris ssp.chinensis L.)为对象,采用根际施用结合叶面喷洒的方法,研究CaCl2、壳聚糖(chitosan,CTS)和水杨酸(salicylic acid,SA)两两复配及三元复配对小白菜盐胁迫逆境的诱抗作用。结果表明:SA,CTS,CaCl2复配施用均能显著降低盐胁迫下小白菜的盐害指数,降低小白菜叶片的丙二醛(MDA)含量,增强过氧化物酶(POD)活性,提高叶绿素含量。各处理以CTS+CaCl2复配施用对小白菜的诱导抗盐效果最好,对小白菜生长的促进作用最显著。SA,CTS,CaCl2三元复配的效果不如二元复配效果好,复配后存在一定的拮抗作用。 |

| Abstract: | The inducing effects of CaCl2,chitosan(CTS),and salicylic acid(SA) binary compound and ternary compound on salt resistance of Brassica campestris ssp.chinensis L.with the method of rhizosphere and foliar spray were investigated.The results showed that SA,CTS,CaCl2 complex could significantly reduce the salt injury index,malondialdehyde(MDA) content,enhance peroxidase(POD) activity and chlorophyll content of pakchoi.The treatment with CTS+CaCl2 showed the best salt resistance and the most significant promoti... |
