Studies on Morphological Characters and Spawn Quality of Oyster Mushroom (Pleurotus Flabellatus)

Abstract

Pleurotus species are cultivated in limited scale and contribute only 14.2 per cent of total annual production of world (Chang, 1999). The present investigation ware carried out on "Studies on Morphological Characters and Spawn Quality of Oyster Mushroom (Pleurotus . jlabel/atus) ''. The results of present investigation to study the Pleurotus jlabellatus species in term of cultural, morphology and yield of sporophores. The result showed that the colony colour of species P. jlabe//atus was observed appresed as white circular and even type margin. Among the chemicals. Maximum radial growth of P. jlabel/atus was observed in calcium carbonate (90.00mm) and maximum radial growth was fow1d in Barley extract agar medium (90.00 mm) respectively. In sugar solution viz. Fructose, maltose, sucrose, starch and glucose results revealed that maximum radial growth was found in glucose (90.00mm) in P. jlabel/atus. For spawn improvement, oat grain was significantly superior to other grain spawn in P. jlabel/atus. Among all the five sugar mixed substrates, maximum mycelial growth (90.00 mm) was fow1d in glucose on 15 day. Maximum yield of P. jlabe/latus was recorded (522.00 g/Kg of dry substrate) recorded at 6% spawn rate experiment. In case of organic supplement the maximum yield (643 g/Kg dry substrate) and average number of fruiting body (24.33 per bag) were noticed in pigeon pea flour. For the grain spawn, higher yield of P. jlabellatus were obtained from oat grain spawn (693.75 g/Kg dry substrate), respectively
