| Abstract/Contents: | "The temperature has an effect on growth and development of the organs of the plant by influencing the speed in which most of the physiological events (photo-synthesis, breathing, closing of the stomata) take place. The optimum temperatures fluctuate for the surface parts of the plants between 15C and 25C for species under moderate climate conditions, and between 27C and 35C for tropical species. For parts of plants below the surface level the optimum temperatures range between 7C and 23C for species under moderae climate conditions and from 24C to 30C for tropical species. Beyond these limits growth and development suffer. On the whole, the temperature itself ver rarely causes the dying of plants (with Poa annua being one of the most sensitive species). However, the plants run a higher risk in their early development stage. This should be taken into consideration in the sowing and keeping processes of turf grounds. The toleration of heat is based on the stability of the protoplasme proteins with regard to high temperatures as well as the ability to re-establish in the cells of a sufficient level. This depends greatly on growth conditions and on way the lawn is kept. It changes with age and with type of tissue. According to findings in the south of France relating to the effects of the temperature the following range of species has resulted, not to forget that there are differences in species: tropical species (Zoysia chodon), smooth stalked meadow grass, reed fescue, fine bent grass, German perrenial rye=grass, sheep's fescue and red fescue, with differences of the red fescue type. These results conform mostly with observations made by H.B. Beard in the USA. When, however, heat and dryness occur at the same time, this sequence is modified, as observations in Lusignan(France) revealed, in favor of low growing fescue types. There are no techniques which would indeed be effective against high temperatures. But the damage can be kept low by observing certain cultivation techniques (Maintaining sufficient moisture levels in the soil, raising the level of clipping, syringing) and through the selection of species and varieties which are more resistant to stress." |
