VII. Biomass production(Ceylon Journal of Science, Biological Sciences, 1983) Amarasinghe, L.D.; Pemadasa, M.A.Biomass accumulation was studied monthly on 2 montane grasslands in Sri Lanka at 900 m and 560 m alt. from June 1976 to May 1977. The upper site was a dense sward dominated by Cymbopogon nardus (65.4%), Themeda tremula (25.4%) andEulalia trispicata (10.1% of standing crop) and the lower site was a sparse sward dominated by C. nardus (68.6%) and Panicum maximum (13.9%) with somePennisetum polystachyon (7.7%). Total standing crop biomass was higher at the upper site than at the lower site and increased 4-fold at both sites over the years. Productivity estimates were 911.2 g/m² for the upper sites and 679.5 g for the lower site. There was no significant difference in the amount of C. nardus between sites, but the upper site supported a much denser sward of T. tremula accounting for the higher productivity of this site.Item Efficacy of Human Chorionic Gonadotropin (HCG) and crude pituitary extract of fish and frog in oocyte maturation and ovulation in African catfishes, Clarias glariepinus Burchell, 1822 Clarias anguillaris Linnaeus, 1762(Sri Lanka Association for the Advancement of Science, 1991) Hettiarachchi, M.Item Effect of light on mortality and growth of embryos, larvae and fry of catfishes, Clarias glariepinus Burchell, 1822 Clarias anguillaris Linnaeus, 1762(Sri Lanka Association for the Advancement of Science, 1991) Hettiarachchi, M.
