采用盆栽沙培试验,研究了缺铁处理及重碳酸盐胁迫下丛枝菌根真菌地表球囊霉对枳实生苗抗活性氧系统的影响。试验结果表明,在缺铁以及重碳酸盐胁迫处理下,丛枝菌根真菌显著提高了枳叶片和根系中可溶性蛋白含量、超氧化物岐化酶活性、过氧化物酶活性和过氧化氢酶活性,明显增强了叶片类胡萝卜素含量,显著降低了枳叶片和根系中的丙二醛含量,增强了枳自身防御能力,减少了胁迫对枳细胞膜的伤害。 Pot experiments were conducted to study the effects of arbuscular mycorrhizal fungi on the active oxygen system of Trifoliate orange seedlings under iron deficiency and bicarbonate stress. The results showed that arbuscular mycorrhizal fungi significantly increased soluble protein content, superoxide dismutase activity, peroxidase activity and hydrogen peroxide in leaves and roots of the leaves under iron deficiency and bicarbonate stress Enzyme activity significantly increased the content of carotenoids in leaves, significantly reduced the content of malondialdehyde in leaves and roots of Citrus aurantium, enhanced the defensive ability of trifoliate orange and reduced the damage to the membrane of citrus.
