Carbohydrates in Grasses. IV. Influence of Temperature on the Sugar and Fructosan Composition of Timothy Plant Parts at Anthesis1
- Dale Smith2
Grams of dry matter and percentages of total nonstructural carbohydrates were higher in all parts of plants grown under cool than under warm temperatures. Temperature influenced the levels of fructosans accumulated, but had little effect on the levels of total sugars and starch. Under cool temperatures where fructosan percentages were highest, long-chain fructosans were found in the stem base, stem plus leaf sheath, and root fractions, but only short-chain fructosans occurred in the heads and leaf blades. Water-soluble carbohydrate (total sugars plus fructosans) percentages as high as 30% were obtained in some leaf blade samples of plants grown under cool temperatures.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
