谷类作物的平均粒重(KWT)在高于临界温度时往往降低(Chinoy,1947;Asana等,1965;Spiertz,1974;Ford等,1976;Sotiel等,1977;Cohwdhury等,1978;Bhullar等,1983)。小麦的临界温度为18℃,高粱的为25℃。当温度由10℃升至30℃时,这两种作物的暗呼吸都逐渐增强(Chowdhury等,1978;

The average grain weight (KWT) for cereal crops tends to decrease above the critical temperature (Chinoy, 1947; Asana et al., 1965; Spiertz, 1974; Ford et al., 1976; Sotiel et al., 1977; Cohwdhury et al., 1978; Bhullar et al., 1983 ). Wheat has a critical temperature of 18 ° C and sorghum of 25 ° C. Dark respiration was gradually increased in both crops as the temperature rose from 10 ° C to 30 ° C (Chowdhury et al., 1978;
