Description |
The three conifer-predominated forest sites in Zabarvan forest range in Kashmir valley viz., Dachigam, Shalimar and Shankaracharia hills were surveyed for three consecutively years (2010-2012) with the aim to document the existing macrofungal flora. The soil physico-chemical properties in the forest sites surveyed revealed that soils were loamy-sand to silty-loam with organic carbon content, pH and EC varying from 3.8 to 4.8 per cent, 5.0 to 5.6 and 0.1 to 0.4 dsm- 1, respectively. The total available macro-nutrients viz., nitrogen, phosphorus, potassium, sulphur, magnesium and calcium were 111-169, 6.5-13.8 and 35.1- 60.6, 6.6-7.3, 16.2-17.2 and 46.4-47.0 ppm, respectively. The micro-nutrients viz., Cu, Zn, Fe and Mn ranged from 1.1 to 1.7, 1.2 to 2.8, 18.2 to 31.4 and 6.0 to 12.2 ppm, respectively. Periodic trips were made to collect macrofungal samples which appeared during these years. Forty three macrofungal species were identified and of these 13 species (30.23%) were mycorrhizal in nature and rest species nonmycorrhizal. Thirty three (33) species were noticed in Dachigam, twenty three (23) species in Shalimar hills and twenty nine (29) species in Shankaracharia hills. Nine macrofungi belonged to Sub-Division Ascomycotina and rest belonged to Basidiomycotina. Temporal distribution revealed the presence of higher number of macrofungal species in 2011 (37 species) followed by 2010 (30 species) but less in 2012 (29 species). The seasonal distribution of macrofungi revealed the presence of more macrofungal species in autumn (36 species) and summer (17 species) than in spring (15 species). The mycorrhizal species were observed more in autumn season (10 species) and less in summer seasons (2 species). Dachigam forests harboured rich non-mycorrhizal flora (26 species). Much species-diversity was observed in Russula (4 species), Agaricus (3 species) and Coprinus (3 species). During survey, two hitherto unreported macrofungi viz., Peziza retrocurvata and Xylaria polymorpha from Jammu & Kashmir State were recorded. Thirteen mycorrhizal isolates were evaluated in vitro for their acid phosphatase activities. The phosphatase activity in evaluated mycorrhiza varied from 3.55 to 6.61 mg r-nitrophenol released g-1 h-1 with maximum activity in Ramaria formosa (6.61) and minimum in Astraeus hygometricus (3.89) and Boletus subtomentosus (3.55). Six edible macrofungi was assessed for their antioxidant activity in three different solvents. Maximum antioxidant activity was observed in Agaricus bisporus (87.0%) in methanol solvent and less antioxidant activity in Ganoderma lucidum (83.5%). Some macrofungi viz., Boletus subtomentosus, Laccaria laccata, Suillis cavipes, Ramaria formosa, Russula emetica R. lilacea were frequently noticed across the Zabarvan forest range. These dominant ectomycorrhiza showed high interspecific variation in their ITS region, hence revealed distinct polymorphism, except in Russula emetica and Russula lilacea which were less diverse. |
