Abstract/Contents:"Physiology includes processes, activities and phenomena characteristic of living matter. In turfgrasses, physiology has received moderate attention with most Universities working with some aspects of it. Over the past 10 years, several rhizotrons have been constructed (Texas, Ohio, Nebraska and Georgia) to study root and shoot relationship in turfgrasses. This aspect of physiology has resulted in the "spring root decline" phenomena, seasonal rooting patters, changes in root to shoot ratios and influences of cultural and nutritional practices on root growth and development. In relationship to cultivar development, physiological parameters are being characterized and studied as keys for recovering elite germplasm. Canopy characteristics, leaf orientation, and stomata features have been investigated as selection criteria for isolating low water use cultivars in Texas. Rooting depth, size and extension have been investigated as mechanisms of drought tolerance in Texas and in the planning stages in Florida. Other physiological characters such as internode length, leaf width and length and lateral stem extension are measured and used as initial selection criteria in cultivar development in New Mexico. Physiology associated with warm and cool turfgrass response to saline irrigation have been recently published from Texas and Florida. Over the recent past, research involving measurements of physiology at a molecular level has not received wide attention. Measurement of metabolic events such as photosynthesis, respiration, carbohydrate storage and partitioning and enzyme activities, have received little recent attention. This aspect of physiology provides the most fundamental basis of turfgrass science and may need to be an area renewed attention."
