不同生态条件下烟草品种烟叶腺毛密度的变化

对7个烤烟品种在4个生态区烟叶腺毛密度的电镜扫描测定，结果表明：品种间、生态间烟叶的腺毛密度差异较大，且有一定的变化规律；生态因素和品种因素对烟叶腺毛密度均有较大的影响，但生态因素是影响烟叶腺毛密度的主要因素。烟叶腺毛密度与烟叶的品质有关，为此，根据品种间、生态间烟叶特有的腺毛密度特性，可以估测烟叶品质和烟草品种在不同生态区的适宜种植程度，为烟草品种的合理布局和区域化种植提供科学依据

Chang of Tobacco Leaf Tentacle Density in Different Areas

Study on tobacco leaf tentacle density in different areas,it showed that the tentacle density had more different between varieties and areas.The areas and varieties factors had higher effect on tobacco leaf tentacle density,but the areas was the main factor.It had relations between tobacco leaf tentacle density and its quality.Acctoding to tobacco leaf tentacle density,we can estimate its quality and suitable plant degree.
