Abstract/Contents:Discusses the functions of water in turfgrass, describing its use in photosynthesis and hydrolysis. Describes the uptake of water from the soil, stating that "water will enter root cells only when the water potential inside the root is less than the water potential of the soil solution... water will move from a high potential in the soil to a lower potential in the roots, consistent with the general laws of nature and energy." Explains that "the force that drive the flow of water from roots to shoots is generated by the evaporation of water from leaf surfaces (transpiration)." Discusses how water is transported to the leaves, stating that "the negative water potential (suction) generated by transpiration from the leaves is transmitted through the vessels to the roots, where it causes water to flow toward the leaves replacing that lost through transpiration." Describes aquaporins, "intrinsic membrane proteins." States that "because aquaporins are proteins, their synthesis is directly under genetic control, which in turn is influenced by environmental, developmental and positional factors." Concludes that "understanding what environmental signals will enhance water movement...can be exploited by turf managers to increase water use efficiency or increase drought tolerance. Within a short time, this knowledge will likely be translated into improved turf management practices for greater water economy."
