The present study was undertaken at eight different sites of Kedarnath Wildlife Sanctuary (KWLS) of Garhwal Himalaya, India to understand the physico-chemical properties of soils and influence of bryophytic communities on the status of nutrient availability. In the bryophytes dominated sites the values of organic carbon (0.21%) and nitrogen (0.04%) were found to be low as compared to values for forest soils dominated by higher plants which suggests that bryophytes prefer to occupy the barren sites with low organic matter. Mean available phosphorus content in soil of various sites varied between 13.02 Kgha-1 and 16.28 Kgha-1 with estimated mean exchangeable potassium content ranged between 145.60 Kgha-1 and 216.16 Kgha-1. A significant negative correlation between soil temperature and moisture content was observed, whereas organic carbon and available phosphorus exhibited significantly positive correlation. Besides the characteristics of soil underneath the bryophytic vegetation, the study also highlights the kind of bryophytes communities found along altitudinal variation and soil types.Keywords

Present study deals with the structure and development of conducting elements in the nine orders of acrocarpous mosses. The significance of conducting tissues in mosses in relation to their habitat conditions, growth forms and leaf cell patterns has been discussed. Features of cells in different portions of the stem and the laminal cell patterns and costa are taken into consideration. Although water-conducting cells are unspecialized in mosses, yet the study shows that they seem to play a vital role in the conduction and provide additional criteria for the distinction of taxa. Four categories have been determined as (i) Acrocarpous mosses with a distinct thick-walled conducting strand (6-7 layered) as hydrome which is surrounded by patches of leptoids. Cortex consists of thick walled cells (6-10 layered). Costa has stereidal cells and well developed conducting elements in leaf, example Polytrichum (ii) Acrocarps with thick-walled, narrow, elongated conducting strand (4-5 layered), cells angular in the cortex (6-8 layered). Leaf cells are rectangular, irregular and porous with incrassate walls, example Dicranum (iii) Acrocarps with conducting tissue (2-5 layered) stereidal, thick walled or thin walled varying in the course of development. Leaf cells are mutipapillate, rounded-quadrate, costa is present, examples Hyophila, Philonotis and (iv) Epiphytic pleurocarps with conducting cells rudimentary, thickened, scattered (2-4 layers) and parenchymatous, cortical cells (2-3 layered) thick walled. Leaf cells are small, rounded or linear and papillate, costa may be present or absent, example Leucodon. The study would constitute a formidable task, especially if intraspecific structural variability is considered. It serves a model system in the eco-physiological aspects.Keywords

Lilium polyphyllum D. Don ex Royle (Liliaceae) is a critically endangered herbaceous perennial, commonly known as white lily or Ksheer kakoli. Bulbs of the plant are of immense medicinal use and have a stringent and anti-inflammatory properties. Over exploitation of the species from the wild and degradation of habitats are posing threats to its existence. In the present study, a protocol was standardized for micropropagation and mass multiplication of the species from scale leaves. Callusing was induced in basal MS medium containing 2,4-D (6.78 μM) and BAP(4.4 μM), where maximum effect (95.32%) was recorded. Maximum shooting (97.45%) was found in the calluses when shifted to MS medium fortified with BAP (4.4 μM), NAA (0.53 μM) and GA3 (20 ppm) with an average of 19.2 shoots/per culture. The well developed in vitro regenerated shoots were shifted to the ischolar_maining medium and 100% ischolar_maining was achieved in half-strength MS basal medium enriched with IBA(9.8 μM). The in vitro regenerated plant lets were shifted to a glasshouse for acclimatization and finally transferred to the open environment with 85% success.Keywords
