Abstract
A study of the life cycle and the factors affecting germination of two ecotypes of Echinochloa colona was conducted at the Weed Science Laboratory and Greenhouse at the Biological Science Building, U. P. at Los Baños, College, Laguna.
Life cycle of both ecotypes was completed within 90 days. Both ecotypes followed a sigmoid growth curve. Percent germination, days to germinate and seed production of ecotype 1 were significantly different from that of ecotype 2. Days to flowering and reproductive capacity of both ecotypes were not significantly different from each other.
Light quality, temperature, chemicals and soil moisture affected the germination of both ecotypes.
Results of the study clearly distinguished the two ecotypes of E. colona from one to another or the basis of growth pattern and development, reproductive capacity and factors affecting germination.
