Abstract
Properly managed turfgrasses mostly process energy for leaf production and maintenance. This chapter presents an overview of the energy dynamics within turfgrass plants covering both diurnal and seasonal cycles. It emphasizes the energy relations that support the growth and development of a turfgrass stand. Two basic pathways for photosynthetic CO2 fixation have been identified: reductive pentose phosphate cycle and photosynthetic dicarboxylic acid cycle. High photorespiratory rates contribute most to the decline in CO2 assimilation by cool-season grasses when grown under high temperatures. The chapter presents a fragmentary picture pieced together from a few studies that bear directly or indirectly on the subject of energy partitioning in turf. The total nonstructural carbohydrate content of tissues is often used as an indicator of the physiological status of turfgrasses.
