Abstract
Orchard grass (Dactylis glomerata L.) was examined as new top growth was produced at 22 C after acclimation to 22 C and 35 C and as new growth was produced at 35 C after acclimation to 22 C and 35 C Ribonucleic acid concentration of top growth decreased rapidly during a 5-week sampling period, and the rate and magnitude of decrease was greater in plants grown at 22 C than at 35 C. During the first 2 weeks, plants grown at 22 C contained higher concentrations of ribonucleic acid than those grown at 35 C, whereas the reverse was true during the latter 3 weeks The deoxyribonucleic acid concentration decreased during the sampling period, but the decrease was much less than with ribonucleic acid Shortly after top growth was removed, total water-soluble carbohydrate concentration of stubble was at a low level and varied irregularly. After 3 weeks, the concentration began to increase, and plants grown at 22 C accumulated more reserve carbohydrates than those grown at 35 C. Water-soluble nonreducing carbohydrates were at a higher concentration than reducing carbohydrates and followed the same trend as total water-soluble carbohydrates. Reducing carbohydrate concentration, however, was greater in plants grown at 35 C than in those grown at 22 C Leaves were examined microscopically and the results are discussed
