Abstract: [Objective] Enhancement on the growth, development and stress resistance of rice plants from the colonization of the endophytic fungus Piriformospora indica (Pi) on the roots was investigated. [Method] Pi was inoculated on 8 different media for optimal culture and co-cultured on rice seedlings to determine the biological improvements on the plants. [Result] Medium V8 was found to be most desirable for Pi growth. Addition of a certain amount of sucrose would further increase the effect. The plant height, leaf length, root length, root count, chlorophyll content and quality of the above- and underground parts of the treated rice plants were significantly greater than those of control. Notably, 20 days after the inoculation, the plant height increased by 32.36% and chlorophyll content 15.88%. [Conclusion] Pi significantly promoted the growth and development of rice plants as it symbiotically enhanced the photosynthesis and root physiology of the host.

Key words: Piriformospora indica, medium, rice, growth enhancement
