Abstract/Contents:"The effects of stage of development on net photosynthesis, dark respiration and distribution of 14C-Photosynthate in Merion Kentucky bluegrass (Poa pratensis L.) and Pennlawn red fescue (Festuca rubra L.) were evaluated. Lateral shoot development occurred after the third (3 weeks after seedling emergence) and fifth leaf stage (3 to 4 weeks after seedling emergence) in Pennlawn red fescue and Merion Kentucky bluegrass, respectively. Tillers were initiated in the axils of leaves below fully expanded leaves in both species. Tiller development preceded rhizome initiation in red fescue; whereas, tillers and rhizomes were not initiated preferentially to one another in Merion Kentucky bluegrass. High dark respiration rates and a large percentage of leaf dry weight occured [occurred] at the first sampling period. The percent distribution of 14C-photosynthate shifted from the leaves-to stems between the second and third week after seedling emergence in Kentucky bluegrass; whereas, this shift occurred between the third and fourth week after seedling emergence in red fescue. The stem fractions were the dominant sinks for photosynthate after the second and third week following seedling emergence in Pennlawn red fescue and Merion Kentucky bluegrass, respectively. The changes in these morphological and physiological responses during seedling growth may indicate critical development periods."
