| Abstract/Contents: | "Turf receiving applications of nitrogenous fertilizers during the late fall season has been found to retain color longer and to regain color earlier the following growing season without stimulation of excessive spring growth. Influence of this practice upon the carbon assimilate pool is of interest in reference to spring growth and low temperature hardiness. Treatments of 2 kg N/200 square meters were applied October 1 and 15, November 1 and 15, December 1 and 15 to separate plots. The nitrogen source was ammonium nitrate. The turf was mown regularly at 3.8 cm and irrigated as needed during the summer months. Sample tissue was removed from the plots at two week intervals throughout the autumn, winter and spring. Basal culm, lower leaf sheath and apical meristem tissue was analyzed for carbohydrate content after extraction with a graded ethanol-water series, providing information on relative polymerization of the carbohydrates present. There was a rapid increase in all soluble carbohydrate components studied during November, the period of hardening in Rhode Island, followed by a more gradual increase during winter. The levels of total, long chain and short chain carbohydrates found appeared to be adequate for energy to support new growth at the end of the dormant season irregardless [regardless] of the time of N application the previous autumn. The levels of the short chain polymers were little effected by the N treatments. The amount of long chain polymers was, however, influenced by N treatments. Reduction in the long chain polymers may account for reduced cold tolerance found in a companion study." |
