摘要

The present study was conducted on density, basal area and biomass production of grasses in two Chir pine plantations (Site I and II) of Solan Forest Division, H.P., India, which is located in the Western part of Southern Himachal Pradesh having latitudes 30 degrees 05' and 31 degrees 15'N and longitudes 76 degrees 42' and 77 degrees 20'E. Site I represented good site quality and Site II the poor site quality. In all six grass species were recorded in the study Sites. Total density (tillers/m2) of the grasses varied between 525.00 to 1676.67 in Site I and 604.00 to 1699.00 in Site II. Basal area (cm2/m2) of grasses ranged from 48.676 to 108.673 in Site I and 52.893 to 109.682 in Site II. Total belowground biomass (q/ha) of grasses in Site I varied from 9.56 to 17.02 and in Site II from 7.92 to 17.81. Total aboveground biomass (q/ha) of grasses on different sampling time, in Site I, varied from 10.12 to 23.48 and in Site II from 9.75 to 27.55. Among grasses Chrysopogon montanus was the main contributors to various attributes of vegetation in both the sites. Site quality did not influence diversity, density, basal area and biomass production of grasses.
