烟草开花研究进展

Recent Advances on Tobacco Flowering

摘要: 针对烟草的成花决定、开花诱导、成花信号以及生产上存在的早花问题进行了讨论,并提出了烟草在诱导开花过程中有待进一步研究的问题:①诱导感受态的存在,低温诱导和光周期诱导的敏感时期是否一致,诱导时间是否有临界期限;②不同诱导条件生理信号是否相同,信号传导途径是否一致;③应答基因的启动和表达,及表达过程中的影响因素等。

Abstract: The research progresses in tobacco flowering from the following aspects:floral determination, flowering induction, floral signal and early flowering of tobacco were reviewed, and the problems in flowering induction of tobacco were also presented for further research.
