Methods: The plant extracts were evaluated for the presence of secondary metabolites such as alkaloids, glycosides, flavonoids, proteins, carbohydrates, terpenoids, resins, saponins, phenolic compounds and tannins phlobatannins and volatile oils following standard methods. Results: The analyses indicated that 34 (100%) species contained carbohydrates and proteins and free amino acids,.29%) phlobatannins and only 3 (8.82%) species tested positive for resins. Conclusion: The results revealed the occurrence of several bioactive constituents which could be exploited for their potential applications for medicinal purposes. Among the solvents, water and ethanol revealed maximum number of phytochemicals than methanol and acetone.

Four newly recorded species of Dryopteridaceae from Kashmir valley, India. Biodiversitas 15: 6-11. Habitat diversity, elevation, cloud cover, rainfall, seasonal and temperature variations have created many ideal sites for the luxuriant growth of pteridophytes in the Kashmir valley, yet all the regions of the valley have not been surveyed. In Kashmir valley the family Dryopteridaceae is represented by 31 species. During the recent extensive field surveys of Shopian district four more species viz., Dryopteris caroli-hopei Fraser-Jenkins, Dryopteris blanfordii subsp. nigrosquamosa (Ching) Fraser-Jenkins, Dryopteris pulvinulifera (Bedd.) Kuntze and Polystichum Nepalense (Spreng) C. Chr. have been recorded for the first time from the valley. The taxonomic description, synonyms, distribution and photographs of each species are given in this article.

New Records of Pteridophytes for Kashmir Valley, India. Biodiversitas 15: 131-136. During the recent field survey of district Shopian four species of Pteridophytes are reported for the first time that constitutes new recordsfor Kashmir valley. These species are Hypolepis polypodioides (Blume) Hook, Pteris stenophylla Wall. ex Hook. & Grev., Dryopterissubimpressa Loyal and Dryopteris wallichiana (Spreng.) Hylander. The diagnostic features of H. polypodioides are presence of longcreepingslender rhizome and eglandular, colorless or brown tinged hairs throughout the frond. P. stenophylla is characterized by havingdimorphic fronds and 3 to 5 pinnae clustered at stipe apex. D. subimpressa is marked by pale-green lamina and the largest basiscopicbasal pinnule in the lowest pair of pinnae. Similarly, the characteristic features of D. wallichiana are presence of huge frond size,glossier and dark-green lamina and dense browner scales in stipe and ...

Ferns and fern allies of District Shopian, Kashmir Valley, IndiaBiodiversitas 16: 27-43. Shopian, recently created hilly district of Kashmir valley, Jammu and Kashmir is surrounded by the loftymountains of Pir-Panjal range. More than half area of district is occupied by different forests, subalpine, alpine and mountainous zones.Great altitudinal variation, adequate rainfall, high forest cover, large number of streams, springs and topographic variations render thedistrict worthy for supporting rich fern flora. Therefore, the current study was aimed to undertake in-depth systematic survey of differenthabitats of Shopian for the collection of diversity of pteridophytes. Specimens were collected during 2010, 2011 and 2012 growingseasons from June to November. A total 81 species of ferns and fern allies belonging 27 genera and 11 families were reported. Thedominant families of the region are Dryopteridaceae (25 species) followed by Woodsia...

The identification and characterization of many of these fungi however largely involves morphological descriptions of sporocarps alone, thus sometimes raising questions about the authenticity of these studies. The present study was carried out to identify and characterize ectomycorrhizal fungi from the coniferous forests of Kashmir Himalaya using both morphological and molecular methods. Herein we report on the identification and characterization of three potential ectomycorrhizal Cortinarius fungal species, namely, Cortinarius flexipes (Pers. Ex Fr.), Cortinarius fulvoconicus M. M. Moser, and Cortinarius infractus (Pers.) Fr., from Kashmir Himalaya, India, on the basis of their morphological and molecular characterization. Morphological characteristics of all species were measured and compared with standard taxonomic literature. ITS-rDNA (the fungal molecular marke...

Thus, we studied macrolichen richness and β-diversity along elevational gradients at three sites, namely Kashmir (2200 to 3800 m a.m.s.l), Uttarakhand (2000–3700 m a.m.s.l) and Sikkim (1700 to 4000 m a.m.s.l) which cover much of the Indian Himalayan Arc. In all, 245 macrolichen species belonging to 77 genera and 26 families were collected from the three sites. Only 11 species, 20 genera and 11 families were common among the three transects. Despite the differences in species composition, the dominant functional groups in the three sites were the same: foliose, fruticose and corticolous forms. The hump-shaped elevation pattern in species richness was exhibited by most of the lichen groups, though an inverse hump-shaped pattern ...

The study resolved the eighty eight plus tree progenies into ten clusters using Mahalanobis D2 statistics. Cluster IV was largest with 21 genotypes (plus tree progenies). The inter-cluster distance was highest (9.901) between cluster IX and VII. Clusters mean indicated that cluster VIII was the best in respect of seedling height (12.82 cm), collar diameter (9.62 mm), needle length (5.76 cm), needle diameter (0.38 mm) and number of needles per seedling (17.44). The superiority of cluster VIII allows use of Arthnari and Seer plus tree progenies for operational plantation purposes.

Mayweed (Anthemis cotula L.), a native of southern Europe-West Siberia is an aggressive invasive species in Kashmir Himalaya, India. Among the myriad of attributes, seedling emergence time is critical to its successful colonization of habitats with varying levels of soil disturbance. Field studies revealed that the species recruits individuals over an extended period of time from September to May. This recruitment period is interspersed by harsh snowy winter (December-February) and hence the established plants of the species are constituted of pre-winter and post-winter populations, with former contributing to the fitness component of its life history and latter to the survival component. Except for number of achenes per capitulum and achene weight, all other investigated parameters such as stem height, number of prima...
