摘　　要：用人工气候箱人为控制温度研究低温对烤烟成花的影响,目的是确定烤烟成花对低温敏感的叶龄期,敏感温度的强度范围,敏感温度持续时间的长短,以探索烤烟开花与环境关系的规律,为防止早花提供依据。结果表明:不同烟草品种对低温的敏感性不同;6叶期左右可能是烤烟对低温较敏感的时期;从播种至现蕾天数、总叶片数这2个指标来看,温度与烤烟成花的关系并非直接相关。Effects of low temperature on tobacco flowering were studied by artificial temperature control to find out rules between tobacco flowering and environment,such as low temperature,its degrees and lasting times,so as to provide guidance for preventing early flowering.Results suggested that different varieties had different sensitivity to low temperature.The six-leafstage was probably the most sensitive stage of tobacco to low temperatures.There were no direct correlation between temperature and tobacco flowering in terms of total leaves and days from seeding to budding.
