Influences of intercropping Paspalum notatum on the olives rhizosphere microenvironment and drought resistant physiology

Abstract

以10年树龄油橄榄植株为试验材料,通过控制土壤含水量及间作或不间作百喜草,测定油橄榄根际土壤理化指标、土壤肥力相关酶活性及叶片生理生化指标,探究间作百喜草对油橄榄根际微环境和叶片抗旱生理的影响.结果表明:随着水分供应减少,油橄榄叶片细胞膜稳定指数显著下降,超氧阴离子(O_2ˉ·)产生速率、丙二醛(MDA)含量及过氧化氢(H_2O_2)含量上升,这表明干旱对油橄榄叶片造成了一定的胁迫和伤害;间作百喜草后,一方面提高了油橄榄叶片细胞膜稳定指数,抑制了O_2ˉ·产生速率、MDA含量及H_2O_2含量的上升,增加了可溶性糖、脯氨酸、Vc和还原型谷胱甘肽含量,增强了超氧化物歧化酶(SOD)、过氧化物酶(..
