双语例句
- The Effect of Nornicotine Quick on the Upper Leaf Unfolding and the Major Chemical Composition
降碱灵对白肋烟上部叶开片及主要化学成分的影响 - There was no significant difference in total alkaloid levels among different cigarette samples in the same year, while nicotine and nornicotine contents varied reversely, resulting in a ladder of percent nicotine conversion in the two separate series of cigarette samples.
同一年份的卷烟样品间总生物碱含量无显著差异，烟碱含量和降烟碱含量呈相反趋势变化，从而形成样品间烟碱转化率的梯度差异。 - Environment Variance has some impact on nicotine but has little impact on nornicotine and nicotine conversion level.
环境方差除对烟碱有一定影响外，对降烟碱和烟碱转化率影响极小。 - Therefore, early generation selection of cross is necessary to decrease nicotine to nornicotine conversion level in burley breeding.
降烟碱和烟碱转化率为高遗传力性状，对杂交后代进行早世代生物碱和烟碱转化率严格选择是十分必要的。 - Impact of nicotine content on the conversion level of nicotine to nornicotine in converter tobacco plants
烟草转化株烟碱含量对其向降烟碱转化程度的影响 - Nicotine and nornicotine in flue-cured tobacco
烤烟中的烟碱和去甲基烟碱 - The results showed that myosmine content increased linearly both in lamina and in midrib as nicotine conversion level and nornicotine content increased.
结果表明，随着烟株烟碱转化能力的提高和烟叶降烟碱含量的增加，叶片和主脉的麦斯明含量呈线性增加。 - The formation of nicotine and nornicotine is affected by varieties, natural conditions and cultural measures, etc.
烟碱、去甲基烟碱的形成受品种、自然条件和栽培措施等的影响； - In natural populations, the correlation of total alkaloid with nicotine and nornicotine decreased, and that with anabasine and anatabine did not change.
在自然群体中，总生物碱与烟碱和降烟碱的相关性减小，与新烟草碱和假木贼碱的相关性没有变化。 - In the natural population contained large amount of converted plants, the nicotine content decreased and the nornicotine content increased, and the nornicotine content was higher than anatabine content.
在含有大量转化株的自然群体中烟碱含量降低，降烟碱含量增高，降烟碱含量高于新烟草碱。 - The results indicated that nicotine conversion rate had significantly negative correlations with nicotine content, and significantly positive correlation with nornicotine content. As the increase of nicotine conversion, the contents of anatabine and anabasine remained unchanged.
结果表明，烟碱转化率与烟碱含量呈显著负相关关系，与降烟碱含量呈显著正相关关系，随着烟碱转化率的增加，新烟草碱和假木贼碱含量无显著变化。
