Abstract
Apple, peach and plum rootstocks were inoculated with the arbuscular mycorrhizal fungus Glomus sp. strain A6 on transplanting from in vitro to in vivo culture. The optimal root length for effective infection, assessed in apple rootstock M 25, was 0.1–1.5 cm, corresponding to the beginning of root elongation. When inoculated at this stage, plants showed maximal growth increase and survival. Mycorrhizal infection of the Mr. S. 2/5 rootstock induced earlier growth renewal after transplanting than in the controls. These results confirm previous reports that mycorrhizal inoculation, performed during transplantation from in vitro to in vivo culture, can enhance both the growth and the survival of plants.
