Abstract: Mycorrhizal dependency of various kinds of plants was estimated in pot cultures. Seeds or cuttings inoculated with Glomus spp. were grown in unsterilized sandy fluvo-aquic soil or sand, fertilized with dilute Hoagland's solution. Results showed that the weight of shoot and root of all mycorrhizal seedlings was significantly greater than that of uninoculated seedlings except chrysanthemum which was generally recognized as a nonmycorrhizal family. Mycorrhizal dependency of different plants decreased in the following order: grape, China rose, white clover, asparagus, violet, petunia, corn, cotton, soybean, tobacco, peanut, tomato, mungbean, lily and chrysanthemum. Mycorrhizal inoculation also enhanced the flowering of China rose and terminal bud growth of pomegranate. There was no correlation between the percentage of mycorrhizal infection and mycorrhizal dependency, although all plants were infected after inoculation.
