Abstract:

利用盆栽实验研究了水分胁迫条件下AM真菌对柠条锦鸡儿(Caragana korshinskii)生长和抗旱性的影响.在土壤相对含水量为80%、60%和40%条件下,分别接种摩西球囊霉(Glomus mosseae)和柠条锦鸡儿根际土著菌,结果表明,水分胁迫对AM真菌的接种效果有显著影响.不同水分条件下,接种AM真菌显著提高了宿主植物根系菌根侵染率.土壤相对含水量为40%~60%时,接种株的株高、茎粗、生物干重和叶片保水力明显高于不接种株;接种AM真菌提高了植株对土壤有效N和有效P的利用率,增加了植株全P、叶片叶绿素和可溶性糖含量以及SOD、POD、CAT等保护酶活性.土壤相对含水量为40%时,叶片MDA含量明显下降.水分胁迫条件下,以接种柠条锦鸡儿根际土著菌的效果最佳.AM真菌增强宿主植物的抗旱性可能源于促进宿主植物根系对土壤水分和矿质元素吸收的直接作用和改善植物体内生理代谢活动、提高保护酶活性的间接作用.
