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.
