STUDY ON PROPAGATION OF Humphreya endertii FROM PHUOC BINH NATIONAL PARK

Abstract

The importance of medicinal mushrooms has been known for centuries. The increasing number of studies on the medicinal value of Ganodermataceae resulted in the development of cultivation technology of these mushrooms. Humphreya endertii, discovered in recent years in Cat Tien and Phuoc Binh national parks, has been identified as a potential medicinal mushroom. Therefore, more studies are needed to be carried out in order to artificially cultivate and produce this species. In this study, media of Humphreya endertii propagation were successfully determined. The agar-media were modified from PDA (Potato Dextrose Agar) containing extract of 200g sweet potato instead of potatoes and has a pH value of 7.0. The development of seed spawn was best achieved on rice grain supplemented with 2.5% rice bran, 2.5% corn bran, and 0.5% peptone. Moreover, the compost composed of rubber sawdust substrate and supplemented with 5.0% rice bran, 0.5% urea, 0.1% MgSO₄ was found to be a favorable subtrates for the mycelial growth. These defined suitable media for the propagation of Humphreya endertii mushroom have place a good foundation for Humphreya endertii cultivation in the near future.
