| 摘 要： | 以一年生桃嫁接苗为试材,在盆栽条件下研究了苹果园土壤中特征酚酸类物质——根皮苷和根皮素对桃苗生物量、根系活力、根系保护性酶活性和MDA含量的影响。结果表明,根皮苷对桃幼苗的伤害显著,与对照相比,鲜质量、干质量分别降低了16.66%和21.58%,根系活力降低了33.04%,SOD、POD活性分别降低了40.80%和31.10%,MDA含量提高了116.34%。根皮素对桃苗的影响不大。高锰酸钾处理明显缓解了根皮苷对桃苗的伤害,苹果园土壤中的根皮苷含量降低了57.80%,提高了桃苗的生物量、根系活力和保护性酶活性,降低了MDA含量。综上,老龄苹果园土壤实测含量的根皮苷(0.343mg·kg~(-1))可降低桃苗的生物量,适量的高锰酸钾能缓解根皮苷的伤害作用。

| Abstract: | The effects ofphloridzin and phloretin (typical phenolic acids in the soil of apple orchard) on the plant biomass,root activity,protective enzyme activities and the content of malondialdehyde (MDA) of one year Prunus persica grafted seedlings were studied under pot condition.The results showed that phloridzin could significantly damage the Prunus persica grafted seedlings,compared with the control,the fresh and dry weight reduced by 16.66％ and 21.58％,respectively.The root activity reduced by 33.04％,and the activities of superoxide dismutase (SOD) and peroxidase (POD) reduced by 40.80％ and 31.10％,while the content of MDA increased by 116.34％.Phloretin had little effect on the Prunus persica grafted seedlings.Potassium permanganate obviously alleviated the damage of phloridzin to Prunus persica grafted seedlings,significantly reduced the content of phloridzin in the apple orchard soil by 57.80％,improved the biomass,root activity,protective enzyme activities of the peach seedlings and reduced the content of MDA.In conclusion,phloridzin(0.343 mg · kg-1)measured in old apple orchard soil could reduced the biomass of the peach seedlings,and moderate potassium permanganate could alleviate the damage of phloridzin on the peach seedlings. |
