丛枝菌根在芦荟育苗中的应用

Study on Application of Arbuscular-Mycorrhizas in Growing Seedlings of Aloe vera

利用6种丛枝(AM)菌和1种AM菌剂对库拉索芦荟Aloe vera组培幼苗接种的结果表明:供试菌种或菌剂均可使幼苗形成丛枝菌根,感染率达96.67％～100%,感染指数达73.30～86.67;接种13个月的苗高比对照增加19.85％～51.91％;叶片长度比对照增加56.67％;芦荟幼苗经接种后,叶片汁液的干物质含量,比对照分别增加13.13％～150.96％。接种15个月的芦荟幼苗叶汁鲜重比对照增加60.87％～233.80％;折合有效成分的生药含量,比对照提高2.17倍～7.24倍。

Tissue culture seedlings of Aloe vera L. inoculated with 7 AMF(arbuscular mycorrhiza fungi) in a greenhouse in Guangzhou showed that the percentage of infection was 99.67% ~ 100%,the index of infected was 73.3% ~ 86.67%. After being inoculated 13 months,the seedling high raised 19.88% ~ 51.91%,the leaves length raised 13.13% ~ 150.%% .After being inoculated 15 months,the leaves juice of Aloe vera raised 60.87% ~ 233.8% and the dried of leaves juice raised 217% ~ 724% .
