丛枝菌根菌对草莓连作障碍的防治效果 各处理君迁子苗木生长及角斑病发病情况 Parameters measured at the end of the experiment (after 9 weeks) for plants inoculated with Glomus sp., G. proliferum, G. intraradices and G. versiforme and without AM (–AM), and grown in the absence (–Cspat) or the presence (+Cspat) of Cylindrocladium spathiphylli. Values are means of eight replicates. Values in the same column followed by identical lower-case letters are not significantly different (P 0·05). For each AM fungal treatment, significant differences between –Cspat and +Cspat are indicated by different upper-case letters. Pseudostem height (cm), total leaf surface area (cm2), root and shoot dry weight (g per plant) of Musa acuminata cv. Grande Naine Effect of four Glomus strains on disease severity, measured by the root necrosis index (%RNI), of banana root rot caused by Cylindrocladium spathiphylli. Bars represent SE (n = 8). 机制： 丛枝菌根菌对连作草莓叶片叶绿素含量、SOD 酶活性、MDA 含量及细胞膜相对透性的影响 不接种对照 只接种南方根结线虫 先接种AM真菌, 后接种南方根结线虫 同时接种AM真菌和南方根结线虫 接种AM真菌提高根系对线虫的抗性 　AM真菌对南方根结线虫繁殖体的影响 　南方根结线虫对AM真菌发育状况的影响 增强果树的耐盐性 现象： Height of banana plantlets (cv.
