Bioproductivity in relation to photosynthesis in four grassland ecosystems in Kenya
Abstract
Productivity studies were carried out in four
grassland ecosystems differing in several environmental
constraints using two harvesting programmes;
"Continuous growt.h plo t s" CC G P) and "Permanent
plots" CPP). The effects of environmental factors
and clipping on production were investigated.
Photosynthetic pathway exhibited by each grass species
was ascertained anatomically while rates of photosynthesis
and transpiration and associated leaf
diffusive and mesophyll resistances were determined
at various light and temperature levels
