Correlation of Cold Tolerance at Different Growth Stages in Rice

Li T. G., R. M. Visperas and B. S. Vergara   

Abstract: Cold injury which influence rice production in different rice growing countries occurs at various growth stages. The degree of cold injury depends on the air or water temperature, the cropping pattern, the growth stage of the rice and other factors. It is generally accepted that cold tolerance of rice at one stage is different from another stage. However, Okabe and Toriyama reported that varieties seem to respond similarly to cold temperature at different growth stages. Some varieties have been found to be tolerant at different growth stages. The purpose of this experiment is to find whether cold tolerance scores at different growth stages of different kinds of rice are correlated or not.
