Abstract: Afive compartments system was used to examine ³²P transfer via vesicular arbuscular mycorrhizal hyphal links from red clover to rye grass. The results show that after mycorrhizal fungus were inoculated in the root compartment for donor plant, hypha out of the donor's roots penetrated the central compartment, and reached the root compartment for receiver plant and inoculated its roots. Therefore, hyphal links were formed between roots of donor red clover and receiver rye grass, and could transfer ³²P from red colver to rye grass. The amount of ³²P transfer was decreased as Psupplied to the receiver plant increased.

Key words: Hyphal links, Red clover, Rye grass, Nutrient transfer
