Abstract
Oats (Avena sativa L.), orchardgrass (Dactylis glomerata L.), and Rhodesgrass (Chloris gayana Kunth) were growth in the field under 3 levels of population densities, defoliated at several stages of development, and harvested 3 weeks later. It was found in each of the grasses that the changes in dry weight of regrowth with the development of stage showed no differences by population densities, and every grass showed its own specific pattern of regrowth with the development of stage. It was supposed that these patterns of regrowth may be resulted from both environmental conditions, and morphological and physiological conditions of grasses with the development of stage.
