| Abstract/Contents: | "The influence of temperature on nitrate reductase activity was studied to determine if nitrate reductase is associated with shoot growth inhibition at super- and sub-optimal temperatures. The investigations were conducted in controlled environment chambers with temperature variables of 10°, 15°, 20°, 25°, 30°, 35°, and 40°C. Toronto bentgrass and Tifgreen bermudagrass, the cool season and warm season grass respectively, were chosen because of these distinctly different temperature optimums. The bermudagrass was omitted from the 10° C temperature treatment, and the bentgrass was ommitted from the 40°C treatment because of extremely adverse conditions for shoot growth. The results indicated that nitrate reductase activity did not decrease significantly under temperature stress conditions until observed shoot growth inhibition occured at 35° C and up for bentgrass and 15°C and below for bermudagrass. At high temperatures (36°C to 40°C) samples of bentgrass exhibited and inhibition of growth and nitrate reductase activity while bermudagrass was relatively unaffected. This reduction of activity could be either and inhibition of enzyme synthesis or inhibition of the activity per se. It was found that the activity per se of the bentgrass enzyme preparation was also inhibited by these same temperatures, suggesting that nitrate reductase inhibition may be a factor causing high temperature growth inhibition in this species. The investigation also indicated that when bentgrass is grown at 15°C and bermudagrass at 30°C, the nitrate reductase activity was higher in the leaf blade tissue than in stem tissue, was higher following application of a nitrate nutrient solution, increased with increasing light intensity, and increased with length of light exposure." |
