X-ray Analysis of Tyrosine in Growing Stage of Bamboo (Phyllostachs edulis A. & C. Riviere)

Abstract

The content of tyrosine in different parts of a growing bamboo shoot was determined by x-ray and an automatic aminoacid analyzer. The results of x-ray analysis and of an aminoacid analyzer were in good coincidence with each other. Tyrosine content in each internode at a growing stage was different and it had the maximum value in the most active part of elongation of the bamboo shoot. Tyrosine content was about 30% based on dry weight in the 17th internode of the bamboo shoot which was 349cm in height and was in the fourth week growing stage.
