Heat Stress Effects On Protein Synthesis And Exosmosis Of Cell Solutes In Three Turfgrass Species, David J. Wehner, T. L. Watschke

Office of the Dean (CAFES) Scholarship

Kentucky bluegrass (Poa pratensis L.), annual bluegrass (Poa annua L.), and perennial ryegrass (Lolium perenne L.) differ in their heat tolerance as determined by plant dry weight 2 weeks after exposure to heat stress. The status of the plants at that time depends on the degree of injury that occurs during the stress treatment and the repair or tolerance of that injury. The purpose of this research was to evaluate species differences in the degree of initial injury due to heat stress. The incorporation of radio-labeled leucine as an indicator of the net rate of protein synthesis …
