Cynodon dactylon (L.) Pers., ‘Coastal,’ and Poa pratensis L., ‘Newport,’ were grown in four different temperature regimes to study the effect of temperature upon the accumulation of carbohydrate. Plants were harvested at two‐week periods for 8 weeks and the stem bases were analyzed for alcohol soluble sugars, fructosan, and starch. The highest concentration of carbohydrate occurred at the coolest temperature for both Kentucky bluegrass and Coastal bermudagrass. Carbohydrate accumulation generally increased as a function of time. Alcohol soluble sugar levels were approximately equal for both species at each temperature regime with the exception of a high amount in bluegrass grown at the coolest temperature.
