摘要
研究证明在成苗期(8~10 片叶)和移栽后受到低温诱导的烟苗会提前进行花芽分化,并引起烟草早花。烟草品种NC82、NC89和RG11对低温诱导较敏感,K326、K346对低温的敏感度相对较弱。在移栽前控制烟苗的叶面积,去除25cm2以上的大叶,可推迟低温诱导烟草早花的时间。而烟苗大量去叶(只留上部3片叶)后再进行锻苗移栽,可缩短烟苗移栽后恢复生长的时间,并不会对烟草的前期生长和烟叶产量产生不利影响。
This experiment showed low temperature is the main reason that leads to early flowering. Under the condition that seedling’s leavesunder 25cm2were cut off the tobacco flowering time can be delayed. The treatment of cutting off the priming and keeping 3 leaves on top wouldn’t affect the early growth of tobacco seedling. Neverthless it could improve the yield and quality.
