1. The effects of low temperature on chlorosis expression in rice cultivars including 6 typical ecotypes, Aus, Aman, Boro, Tjereh, Bulu and Japonica, were studied in a controlled environments. 2. When temperature was kept 15℃, many cultivars in Southeast Asia, except Bulu ecotyp, showed a significant decrease in chlorophyll contents of leaves. Low day-temperature have a pronounced effect on chlorosis. The fact suggests that light has an important effect to induce the chlorosis at low temperature. 3. Aus and Tjereh cultivars were highly sensitive to low temperature and expressed typical chlorosis. Japonica and Bulu cultivars, espcially Japonica ones, have high tolerance to inducing chlorosis at low temperature. 4. Wild rice in Asia showed a remarkable chlorosis at low temperature, but cultivated and wild rice in Africa had high teolerance to low temperature inducing chlorosis.
