Abstract

In this study, factors, such as the region, growth stage, harvest time and cultivars, affecting water soluble carbohydrates (WSC) content and sugar composition of timothy were examined. Maximum differences in WSC content (dry basis) were found at the first and second cutting, 2.67% and 2.37%, respectively in different regions. Though the WSC content was at its peak on June 30 (heading stage), glucose, fructose and sucrose contents were constant. The WSC content continued to increase from 7 : 00 to 17 : 00, and resulted in 3.00% (dry basis) increase. The glucose and fructose contents reached its maximum at 13 : 00. The WSC, glucose and fructose contents in Kunpu (extremely early maturing cultivars) and in Nosappu (early maturing cultivars) at the first cutting and the Nosappu at the second cutting were the highest among the four cultivars, while glucose and fructose contents increased only slightly. The obtained results indicate that the WSC content and sugar composition of timothy vary significantly with in the region, growth stage, harvest time and cultivars.
