采用定日长与分期播种相结合的方法,研究了我国烟草现用主体品种的光、温反应的发育特性。结果表明:(1)较低温度可促进烟草花芽分化;(2)大多数品种对日长的反应不敏感,属日中性。另外,还研究了花芽分化的叶龄指标。
Using the combination of fixed-day length and staged sowing, the developmental characteristics of light and temperature responses of main varieties of tobacco in our country were studied. The results showed that: (1) lower temperature could promote tobacco flower bud differentiation; (2) most of the varieties are insensitive to Japanese long-term reaction, which are both neutral and neutral. In addition, leaf age index of floral bud differentiation was also studied.
