RESEARCH ON THE INFLUENCE OF DIFFERENTIATED HYDRATION ON PHYSIOLOGICAL PROCESSES ON TWO LAWN MIXTURES.

Today, in most countries, which have reached a very high level of industrialization, technicalization and urbanization, the conservation and creation of green areas is an important means of protecting man and his living environment. Green spaces are good for human health, not only by creating a favorable microclimate and a calmer environment, with cleaner and better oxygenated air, but also by influencing the neuropsychic state. Lawn is an essential and irreplaceable element for leisure and sports and is more than just grass. It is an indispensable landscape element with multiple values, through its silky texture, attractive appearance, green color, color that represents nature and life, freshness, rebirth, hope and vigor. The aim of the research was to study the influence of differentiated hydration on physiological processes in two lawn mixtures. For this purpose we used two types of lawn, the first, Turfline, composed of a mixture of 3 types of lawn seeds (65% Festuca arundinacea Starlett; 15% Lolium perenne Double; 20% Poa pratensis Geisha) and the second RPR Regenerating, namely Lolium perenne with regeneration by stolons, both irrigated daily and every three days. For the study of differentiated hydration on the two lawn mixtures, we determined the content of chlorophyll pigments in the leaves (SPAD units) and the rate of photosynthesis (%). The results of the research show that irrigation did not significantly influence the chlorophyll content of the two types of lawn. Regarding the photosynthetic capacity of the turf mixtures under study, it is observed that this has higher values in the case of RPR Regenerating, irrigated every 3 days, which indicates that this type of lawn is more resistant to drought than Turfline.
