Effects of harvesting intensities and techniques on re-growth dynamics and quality of Terminalia bellerica fruits in central India     

A. K. Pandey  Pankaj Bhargava 《林业研究》2014,25(1):177-184

Terminalia bellerica Roxb.(Belleric myrobalan)is one of the important multipurpose trees in central India.The fruits of the tree are highly valued for medicinal uses,with the greatest demand coming from the pharmaceutical industry.This has resulted in overexploitation and present harvesting practices have led to a significant decline in natural regeneration for this tree species.Our study was conducted from 2006 to2009 in Chhattisgarh(India)to standardize suitable harvesting practices for sustainable management for this valuable species.Experiments were conducted at four different sites located in Dhamtari,Sarguja,and Raigarh forest divisions of the state,covering both protected and open forest in a complete randomized block design(RCBD).At each site,linear transects of 200 m別100 m(2 ha)were randomly selected to sample the initial population and study the effects of two harvesting methods(traditional and nondestructive)and four harvesting intensities(60%,70%,80%,and 90%)on the sustainability of T.bellerica.Fruits were collected and analyzed for their tannin and gallic acid content.Significant increase in tannin and gallic acid content was found with the maturity of fruits(September to December).This is the first study to experimentally assess the consequences of harvesting of T.bellerica fruits in central India.Our findings reveal that harvesting intensity,time,and method are key factors for maintaining the population.Nondestructive harvesting methods were found to be superior to traditional harvesting in terms of regeneration,recruitment,and concentration of active ingredients.When the fruits were harvested through non-destructive means at maturity,the population of species increased.The study concludes that 70%harvest of T.bellerica fruits through non-destructive means maintains the sustainability and provides quality raw material for the pharmaceutical industry.  相似文献   

Seasonal Variations in Seminal Plasma Proteins of Buffalo     

L Sharma  V Pandey  R Nigam  P Singh  A Saxena  DK Swain 《Reproduction in domestic animals》2014,49(3):387-391

The study was designed to evaluate the influence of season on semen characteristics and seminal plasma protein profile of buffalo bull semen. Thirty‐six ejaculates were collected in three seasons (winter, summer and rainy) from six adult Bhadawari bulls, and semen characteristics were evaluated immediately after collection. The seminal plasma was harvested by centrifugation and protein profiling, and percentage protein fractions were analysed by SDS‐PAGE. The significant effect of season was observed on ejaculate volume, sperm concentration, progressive motility, percentage live spermatozoa, hypo‐osmotic swelling test (HOST) and acrosomal integrity. The electrophoretogram of seminal plasma proteins revealed 20 protein bands in winter, 23 bands in rainy and 25 bands in summer seasons, illustrating the significant effect of seasons on seminal plasma proteins. Among these protein bands, 18 bands were observed common in semen samples of all three seasons while protein bands of 46, 55, 58, 144 and 160 kDa were found in rainy and summer seasons. The protein bands of 48 and 60 kDa were observed only in winter season, whereas 184 and 200 kDa were reported in summer season only. The protein fractions (protein%) of common protein bands observed in three seasons revealed a significant effect of season on protein bands of 24.5, 66, 70, 72, 84 and 86 kDa. From the study, it was pertinent that bull seminal plasma contains specific proteins in particular season, which may be associated with some of the semen characteristics, and these proteins could be used as markers of the semen quality of buffalo bulls.  相似文献   

Resource Availability Versus Resource Extraction in Forests: Analysis of Forest Fodder System in Forest Density Classes in Lower Himalayas,India     

Rajiv Pandey  Steve Harrison  Ajay Kumar Gupta 《Small-Scale Forestry》2014,13(3):267-279

Particularly in developing countries, forests provide feed for livestock in the form of fodder for stall-feeding and grazing in forest areas. Extraction of fodder resources from forests often leads to forest degradation. An attempt has been made to qualify extend of biomass extraction from forests and to compare forest fodder dependence of households in a number of forest density classes in the mountainous region of Himalayas, in Uttarakhand state in India, according to livestock owners’ perspectives. Information was obtained from a survey of livestock feed and fodder collection and utilization from 316 randomly selected households distributed across four government-defined forest density classes, namely very dense forest, moderately dense forest, open forest and scrub. Households obtained feed and fodder for livestock from three sources, i.e. forest areas, non-forest areas and local markets. Daily feed consumption per adult cattle unit varied according to source, ranging from 9.85 to 14.70 kg from forest areas, 7.40 to 11.14 kg from non-forest areas, and less than 1 kg from local markets. The dependency of households on fodder for livestock differed significantly between households located in each forest density classes. The current forest fodder extraction rate is likely to be unsustainable. Measures identified to reduce the extraction rate include greater use of alternative fodder sources and managing small patches of the natural forests adjoining dependent villages for fodder production through community participation.  相似文献

Seabuckthorn, a non-leguminous nodule bearing dioecious shrub, is a storehouse of neutraceutical, pharmaceutical and cosmetic usage. The 348 genotypes of Hippophae rhamnoides ssp. turkestanica, H. salicifolia and H. tibetana were collected from 194 locations at 46 major sites across?~1,500?km from north-east to north-west Himalayas, harboring one of the most harsh, highly variable climatic and ecological conditions and rugged rocky terrain in the range of 3,000–5,000?m altitude. Amplified fragment length polymorphism (AFLP) and selective amplification of microsatellite polymorphic loci (SAMPL) DNA markers were utilized to assess, the genetic diversity of total spectrum of Himalayan germplasm resources and interrelationships among Hippophae taxa. A total of 151, 50, and 41 AFLP loci were detected in Hippophae rhamnoides ssp. turkestanica, H. salicifolia and H. tibetana, respectively; of these, 92.6, 30.6 and 25.1% were polymorphic. For SAMPL, the number of markers and polymorphism for these species were, respectively, 77 (77.7%), 41 (41.4%), and 23 (23.2%). Nei’s genetic diversity and Shannon’s information index values revealed that populations of H. rhamnoides ssp. turkestanica in Sumur and Raling in Ladakh and Lahaul-Spiti, respectively, were the most diverse. In H. salicifolia and H. tibetana, the populations in Changu, and Takcha and Guling in Spiti valley, were the most diverse. In H. rhamnoides ssp. turkestanica, high level of interpopulation genetic diversity with the little intra-population diversity was accompanied by very low gene flow (Nm) range, estimated by AFLP (0.571–0.943) and SAMPL (0.321–0.726) markers. In H. rhamnoides ssp. turkestanica, the genotypes collected from Uttaranchal were found to be the least diverse. The exclusive characteristics of the nuclear genome in the Uttaranchal genotypes warrant new species rank more closer to H. salicifolia rather than to H. rhamnoides ssp. turkestanica. The present results also provide explicit evidence to suggest that both H. salicifolia and H. tibetana deserve species rank.  相似文献

A. Pandey  V. M. Chowdary  B. C. Mal  P. P. Dabral 《Land Degradation \u0026amp; Development》2011,22(3):359-372

Formulation of a proper watershed management plan requires reliable and up‐to‐date information about various factors such as morphologic (size and shape of the watershed, drainage parameters, topography), soil and their characteristics, land use, and land cover, etc. that affect the behavior of a watershed. Satellite based remote sensing technology and GIS meets both the requirements of reliability and speed and are ideal tools for generating spatial information needs. In this study, a locale‐specific watershed development plan was generated for the case study area of a small agricultural watershed of Karso, Hazaribagh, India using remote sensing and GIS techniques. Indian Remote Sensing Satellite (IRS‐1C), Linear Imaging Self Scanner (LISS‐III) satellite data along with other datasets, e.g. existing maps and field observation data have been utilized for generating a land use/land cover map and to extract information on morphological parameters (bifurcation ratio, elongation ratio, drainage density, ruggedness number, relief ratio, and circulatory ratio) and other thematic maps which are an essential prerequisites for watershed development. Morphological parameters of subwatersheds were derived to understand its usefulness for surface water development. The conceptual framework for plan and site suitability mapping for soil and water conservation structures is developed and subsequently, these parameters were integrated with other thematic information viz., land use/cover, drainage, slope, and soil in the GIS environment to arrive at a decision regarding a suitable site for having soil and water conservation structures ( nala bund , check dam, and percolation tank) in its place adopting a holistic approach.
