The heat-unit accumulations required for each leaf unfolding of a hybrid corn, Tomorokoshi Ko No. 7,were calculated by using the degrees of various ranges of a daily mean temperature. The fitness of the temperature ranges for leaf unfolding were evaluated by the coefficients of variation for heat-unit accumulations among leaves. The most qualified temperature range, designated as the effective degree range, that had the least coefficient of variation was from 10℃ to 27℃ and the average of the heat-unit accumulation required for each leaf unfolding in the effective degree range was 36.9℃. The number of heat-units required for the unfolding of a leaf in the effective degrees remained relatively constant for leaves on different nodes, while calendar days varied widely.
