为研究低烟碱烟草的烟碱累积和成熟落黄特性,解析烟碱含量与烟草成熟落黄特性的相关性,以NC95背景低烟碱烟草品种MAFC5、MLAFC34和LAFC53,K326背景低烟碱烟草品种CD01为材料,并以NC95和K326作对照,分析了不同施氮水平对供试烟草材料不同时期、不同叶位叶片烟碱含量的影响,并进行了成熟落黄特性比较.结果表明:随着烟株的生长,低烟碱烟草的烟碱含量逐渐增高;供试低烟碱烟草品种的烟碱含量均低于对照NC95和K326,表现为MAFC5＞MLAFC34＞LAFC53＞CD01,分别较对照降低 39％、43％、79％、96％;MAFC5、MLAFC34、LAFC53 不同叶位叶片的烟碱含量由下至上逐渐升高,而CD01不同叶位叶片的烟碱含量则由下至上依次降低;施氮量增加,各品种烟草烟碱含量均增加,从低施氮量到高施氮量,MAFC5、MLAFC34和LAFC53的叶片的烟碱含量分别增加24.3％、26.1％、19.6％,而CD01仅增加9.9％左右,影响较小;MLAFC34和LAFC53的成熟落黄特性较差,CD01和MAFC5的成熟落黄特性和对照烟草接近.本研究发现低烟碱烟草品种叶片的烟碱含量均低于对照品种,施氮量增加对各品种烟碱含量有不同程度的提升作用,叶片烟碱含量与成熟落黄特性无必然关联.
To study the nicotine accumulation and mature characteristics of low-nicotine tobacco and discern the correlation between nicotine content and the tobacco's mature traits,NC95 and K326 and their low-nicotine tobacco varieties(MAFC5,MLAFC34,LAFC53 in NC95 and CD01 in K326 background)were utilized as experimental materials.Effects of varying nitrogen application levels on the nicotine content of tobacco leaves across different stages and leaf positions were analyzed.The findings revealed a gradual increase in nicotine content in low-nicotine tobacco as the plants matured.Notably,the nicotine content of low-nicotine tobacco varieties was lower compared to the control sets NC95 and K326,with MAFC5＞MLAFC34＞LAFC53＞CD01,exhibiting reductions of 39％,43％,79％and 96％respectively,compared to the controls.Additionally,the nicotine content of leaves of MAFC5,MLAFC34 and LAFC53 increased from bottom to top,while in CD01,it decreased from bottom to top.Furthermore,the nicotine content in the leaves of MAFC5,MLAFC34 and LAFC53 increased of 24.3％、26.1％and 19.6％from low nitrogen application to high nitrogen application respectively,whereas CD01 displayed only 9.9％increase.Regarding maturity characteristics,MLAFC34 and LAFC53 displayed poorer traits compared to CD01 and MAFC5,which were closer to those of the control tobacco.Our study underscores that the nicotine content in the leaves of low-nicotine tobacco varieties is lower than that of control varieties.Moreover,the effects of nitrogen application on the nicotine content varied among all varieties,indicating no inherent correlation between nicotine content and mature characteristics.
