摘要
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。
The response of main tobacco varicties which are used at present to light and temperature and their characteristies of development and growth were studied by fixing the lcugth of day and sowing the tobacco seeds at different times. The resuts showed that (1) for all the tried varicties the differentiation of flower bud was promoted by the lower temperature, and (2) most tried varicties were not sensitive to the lcugth of day, and which could be regarded as neutral. The leaf-age index for the differntiation of flower bud was also studied in the paper.
