Abstract
The cho line contents in various tissues of leaves and stems in several vegetables were determined.The determination was carried out by the Reineckate method using nitric acid hydrolysis.
1) It was found that, in the stems and leaves, the young tissues had a tendency to contain a larger amount of choline than the old ones.
2) In the internodes of bambooshoot, the lower parts contained more choline than inthe upper parts, and it was found that there were many horizontal fibrovas-cular bundles in the lower parts of the internodes.
3) In the stem of sunflower, the vascular bundle contained a larger amount of choline than other tissues.
4) As the leaves of spinach grew older, the amount of choline in them decreased.
