INA细菌对杂柑‘不知火’果实膜脂过氧化和保护酶活性的影响

以杂柑‘不知火’果实为材料,人工接种INA细菌,在模拟自然降温条件下,研究INA细菌对果实霜冻害的影响。结果表明：接种INA细菌能提高果皮相对电导率,破坏果皮膜保护酶SOD、POD、CAT的活性,使细胞积累大量自由基,并增强膜脂过氧化作用,加剧MDA含量的积累,使果实在较高低温下受冻。因此,INA细菌可诱发和加剧‘不知火’果实霜冻害。...

Hybrid citrus cultivar ＇Buzhihuo＇ was used to study fruit frost injury with or without INA bacteria.The results showed that under stress of low temperatures,the treatment of INA bacteria could greatly raise relative electric conductivity,permeability of cell membrane and content of MDA,and cut down SOD,POD and CAT activity of fruit.The treatment of INA bacteria could raise the temperature of frost injury,and INA bacteria was one major factors to incite frost damage to ＇Buzhihuo＇.Frost injury would be relieved through controlling INA bacteria.
