Studies on the change of chemical-components in growing tobacco plant. : Part 1. On the change of free amino-acids and sugars at the stages of young seedling and of flower formation indicated by the paper partition chromatography method.

Abstract

We have seprarated the free amino acids and the sugars at various stages of growing tobacco plant by means of one dimensional paper chromatography. At the seedling stage (11-12 leaves), a large amount of them were obtained, and immediately after the flower bud formation their increase was especially recognized at the tip of stem.
