Cultural, morphological and yield attributes of winter mushroom Flammulina velutipes (Curt. Fr.) Sing.

摘要

Flammulina velutipes is one of the least exploited mushroom species in India. Out of the total world mushroom production, only 4.6% is contributed by F. velutipes. It has been domesticated on locally available agro-wastes. The highest mycelium growth was observed on malt extract agar medium at 25 C and at slightly acidic-alkaline pH 6.0 for isolate Fv 1 and pH 8.0 for isolate Fv 2. Among the different grains used for spawn preparation, wheat grains were found most suitable as it took minimum time period (17 d). Various substrates, wheat straw (WS), maize straw (MS) and saw dust (SD) were evaluated either alone or along with supplementation of 5 or 10% wheat and rice bran for cultivation of F. velutipes. Wheat straw supplemented with 10% wheat bran resulted in higher yield (593 g 500 g -1 dry substrate; BE 118%) in case of isolate Fv 1, however, WS supplemented with 10% rice bran gave maximum yield (695 g 500 g -1 dry substrate; BE 139%) in case of isolate Fv 2.
