摘要
以摩西球囊霉(Glomus mosseae)为接种菌剂,以紫花苜蓿为研究对象,利用盆栽控水法,研究了水分胁迫下接种AM真菌对紫花苜蓿生长状况与抗旱性的影响。结果表明:水分胁迫时,接种AM真菌的植株体内叶片相对含水量、脯氨酸含量和可溶糖含量显著增加,细胞膜通透性、MDA含量和3种保护酶的活性明显下降;说明接种AM真菌可促进植物细胞渗透调节物质的累积,降低超氧自由基的产生,减缓水分胁迫对植物带来的伤害,促使植物更好地适应矿区干旱环境。
Taking Glomus hosseae as microbial inoculum,taking alfalfa as reseach object,the effects of AM fungi on alfalfa growth and drought resistance were studied by pot experiment under different water conditions. The results showed that when the soil relative water content was 40% ,the plant leaf relative water content, proliae content and soluble sugar content increased significantly after the vaccination of AM fungi, the cell membrane permeability, MDA content and three kinds of protective enzyme activities decreased obviously. Inoculation of AM fungi could promote the accumulation of plant cell osmotic regulation substances content, reduced the super oxygen free radicals, reduced the damage to the plant water stress, prompting them to better adapt to mining area drought environment.
