玉溪烟叶
-
玉溪烟叶中PAL活性高于普洱,其产物中的多酚类物质同样高于普洱。
In Yuxi tobacco leaves , the PAL activity and polyphenol contents were higher than that in Puer tobacco leaves .
-
结果如下:1.玉溪烟叶中SS基因表达水平高于普洱烟叶,SPS和SS活性也较高。
The results showed that : 1 . SS gene expression level , SS and SPS activity were in tobacco leaves of Yuxi than .
-
玉溪烟叶中的蔗糖含量高于普洱烟叶,而淀粉、葡萄糖、果糖含量低于普洱,这是由SPS和SS活性差异造成的。
Sucrose contents in tobacco leaves of Yuxi were higher than that in Puer , but the starch , glucose and fructose contents were lower , which were produced by the differences of SS and SPS activity .

这两个关键酶的活性差异,造成了两地烟叶碳素流向和分配的各自特点,很可能玉溪烟叶碳素更多的流向纤维素类物质的合成,普洱烟叶碳素更多用于淀粉的积累。
It caused respective characteristics of the flow and distribution of the carbon in tobacco leaves . The carbon in Yuxi tobacco leaves flowed more towards to the synthesis of cellulose , and that in Puer tobacco leaves flowed more towards to the accumulation of starch . 2 .

一系列衰老相关基因(GS.GDH)的表达差异和关键酶(GS、GOGAT、GDH)活性差异,造成了玉溪和普洱烟叶氮素代谢的各自特点。
The differences on the expression of senescence-associated genes ( GS , GDH ) and the activity of the key enzymes ( GS , GOGAT , GDH ) caused respective characteristics of nitrogen metabolism between Yuxi and Puer tobacco leaves .
