Abstract

To counter the key techniques of cropping Toona sinensis buds in plastic green houses, the authors systimatically studied the effective accumulated temperature of Toona sinensis germination. Toona sinensis buds germinated at the minimum critical temperature of 6℃ . The effective accumulated temperature from dormancy to germination varied with the provenances, temperature and treatment methods of low temperature . There was no striking dif ference in the efective accumulated temperature of germination and in mean germination period between undormant shoots and dormant shoots, but germination ratio of undormant shoots was by far lower than that of dormant shoots. The function of combinating temporary planting and low temperature treatment could effectively promote earlier germination of undormant shoots and raise the germination ratio. The relavant cropping techniques inplastic green houses were put forward.
