本文主要研究内容
作者李文彬,于建新,宁楚涵,于伟红,张燕,郭绍霞(2019)在《青岛胶州湾四种类型湿地AM真菌多样性》一文中研究指出:对青岛胶州湾4种类型湿地(盐田、滩涂、湖泊和河口)中芦苇Phragmites communis、香蒲Typha orientalis和碱蓬Suaeda glauca根围土壤中丛枝菌根(arbuscular mycorrhizal,AM)真菌进行孢子分离与鉴定,分析湿地生态系统中植物根围AM真菌群落特征。共分离到AM真菌5属10种,包括斗管囊霉属Funneliformis 2种、无梗囊霉属Acaulospora 3种、近明球囊霉属Claroideoglomus 2种、球囊霉属Glomus1种、巨孢囊霉属Gigaspora2种,其中,斗管囊霉属Funneliformis及地斗管囊霉Funneliformis geosporum的分离频度和相对多度最高,分别为湿地中AM真菌优势属和优势种。滩涂和河口湿地中植物AM真菌侵染率显著高于湖泊和盐田湿地植物,AM真菌孢子密度以滩涂湿地最高(572个/20m L),湖泊湿地最低(220个/20mL);滩涂湿地的种丰度和Shannon-Wiener指数最高,分别为3.8和1.2。从植物种类来看,AM真菌侵染率总体呈现出香蒲>碱蓬>芦苇,AM真菌孢子密度以香蒲最高,芦苇最低,植物种类对AM真菌种丰度和Shannon-Wiener指数影响不显著(P>0.05)。二因素方差分析和典型RDA相关分析表明,寄主植物种类对AM真菌孢子密度有一定影响,但湿地类型对AM真菌多样性的影响更为显著(P<0.05),胶州湾湿地土壤因子Ca2+、速效P含量与AM真菌孢子密度、物种丰度和多样性指数显著负相关,而速效K、Na+、pH与其显著正相关。结果表明植物种类主要影响AM真菌孢子密度,AM真菌多样性受植物种类和湿地类型综合影响,滩涂湿地较丰富的AM真菌多样性可能与该湿地较良好的理化性质有关。
