菸草对光照和温度的反应都比较敏感,品种之间差異悬殊。了解不同品种对不同光照和温度的反应特点,是菸草栽培、育种、良种繁育和引种推广等工作的重要步骤。本试验是以我国几个主要烤菸品种为材料,1964年在山东泰安进行的。一材料和方法研究包括两个主要内容:其一,每日光照时数不同对我国几个主要烤菸品种生长、发育的影响;其二,两个烤菸品种的短日光照敏戚期的测定。两个内容分两个试验进行。
Tobacco response to light and temperature are more sensitive to the wide disparities between varieties. Understanding of different varieties of different light and temperature response characteristics, is tobacco cultivation, breeding, breeding and introduction of seed promotion and other important steps. This experiment is based on several major varieties of flue-cured tobacco in our country, in 1964 in Tai’an, Shandong. A material and method research includes two main contents: First, the impact of different daily light hours on the growth and development of several major flue-cured tobacco varieties in China; Second, the short-day light sensitivity of two flue-cured tobacco varieties were determined. The two were conducted in two experiments.
