Assessment of mycelial growth, characteristics and spore morphological characteristics of different species of Pleurotus

Abstract

Oyster mushrooms namely Pleurotus species are described as 'food delicacies' because of their characteristic biting texture and flavour. They may have the most color variety of all edible mushrooms: White, Yellow, Purple, Gray, Brown, and Black oyster mushrooms are common and popular. The distinct flavor of oyster mushrooms makes them a delightful accompaniment to seafood and shellfish. The impact of media on different spp. of Pleurotus (oyster mushroom) were assessed in in vitro condition and morphological characters of spores of different species of Pleurotus, where studied an observation for spore size, shape, color and spore print color was observed. Mycelial growth was differed significantly on PDA (Potato dextrose agar) with each other. The significantly maximum mycelial growth 90 mm with White thick mycelial growth with regular margin was recorded simultaneously in four species viz., PL-17-01, PL-17-02, PL-17-03 and PL-17-05, however PL-17-08 gave significantly lowest (52.5mm) growth with white mycelial growth with two concentric rings and irregular margins. Maximum length (4.0mm) and width (1.85mm) was recorded in PL-17-11 and PL-17-02 respectively while PL-17-12 and PL-17-10 gave minimum length (2.25mm) and width (0.97mm). Oval to cylindrical shape basidiospores where observed in all the studied species of Pleurotus spp. and color of basidiospores was hyaline in all the species. White color spore print was observed in PL-17-01, PL-17-03, PL-17-05, PL-17-06, PL-17-07 and PL-17-08 and grayish color was recorded in four species of Pleurotus (PL-17-02, PL-17-04, PL-17-09 and PL-17-11). Light yellow and cream color was observed in PL-17-10 and PL-17-12 respectively.
