对10个纯培养菌株和17个宿主物种进行了交叉接种实验。从放线菌树根瘤中分离得到10株菌株，分属于4科5属9种。寄主种类分属5属。赤杨纯培养菌株对同属不同物种具有较强的感染能力。接种这些菌株的幼苗能够正常结瘤。这些菌株还可以感染加州杨梅的幼苗并结瘤，但不能感染胡颓子、木麻黄和杨梅的幼苗。胡颓子纯培养菌株可侵染同一属、同一科的宿主物种并结瘤，但大肠杆菌除外。 viridisvardelavayi，少数胡颓子菌株只能很弱地结瘤。来自胡颓子的菌株不能感染赤杨和杨梅的幼苗。这里提出的结果表明弗兰奇内生菌可以分为两个类群：桤木属类群和胡颓子属类群。
Cross-inoculation experiments with 10 pure cultured strains and 17 host species were carried out. The 10 strains were isolated from the root nodules on actinorhizal trees ranging in 9 species, 5 genera and 4 families. The host species belong to 5 genera. The pure cultured strains fromAlnusare of strong ability to infect different species of the same genus. The seedlings inoculated with these strains are able to nodulate normally. These strains can also infect and nodulate the seedlings ofMyrica californica, but not the seedlings of Elaeagnus, Casuarina andMyrica rubra. The pure cultured strains from Elaeagnus can infect and nodulate the host species in the same genus and family with an exception ofE. viridisvardelavayi, which can be only poorly nodulated by a few strains from Elaeagnus. The strains from Elaeagnus cannot infect the seedlings of Alnus andMyrica rubra. The results presented here suggest thatFrankiaendophytes can be divided into two groups: Alnus group and Elaeagnus group.
