摘要
从不同生态条件下采集的林地土壤上长出的蒙自桤木(Alnus nepalensis)幼苗结瘤情况表明:Frankia菌的生态适应力较强,它在林地土壤中的分布相当广,无论在有放线菌根瘤植物存在还是没有的林地土壤中都普遍存在着Frankia菌,即Frankia菌在林地土壤中的生态分布已超出了其寄主植物的生态分布范围.
The results of nodulated seedlings of Alnus nepalensis grown from different soils collected from different ecological conditions shown that: Frankia has a wide ecological adaptibility, and a great range of distribution in forestry soils.They can inhabit and spread in the forestry soils whether there exist actinorhizal plants or not, that is, the distribution of Frankia in forestry soil has exceded the distribution ranges of their hosts.
