In order to explore the regulation between tobacco flowering and temperature-light factor,ensure the intensity rage and lasting time of temperature-light factor for early flowering,the effects of temperature-light factors on early flowering of tobacco were studied by using artificial climate box to control temperature and light.The results showed that the effects of different processing time on early flowering of tobacco were significant;the effects of low temperature on budding time and gibberellin content of tobacco were significant,and the effect of synergistic action was greater;the short-...
