| Abstract/Contents: | "This research was carried out to know an actural [actual] state of photosynthesis and transpiration, in zoysiagrass (Zoysia matrella (L.) MERR.) and bentgrass (Agrostis tenuis SIBTH.) greens. Plant materials for measuring were sampled with hall cutter from both greens. Photosynthesis and transpiration were measured under different light and temperature conditions. On the basis of these data, water use efficiency, leaf conductance and intercellular CO2 concentration were calculated. Light saturation point and maximum photosynthetic rate of zoysiagrass green were higher than those of bentgrass green. There were no differences between both greens in light responses of transpiration and water use efficiency. The light response curve of leaf conductance and intercellular CO2 concentration showed reciprocal patterns in both greens. However, those values of zoysiagrass were smaller than those of bentgrass. The optimum temperature of photosynthesis was shown in higher temperature side (30 degrees celsius) for zoysiagrass and in lower temperature side (15~20 degrees celsius) for bentgrass. The response of dark respiration to temperature showed the same pattern in both greens, and Q10 value was around 2.0. The CO2 valance decided by apparent photosynthesis and dark respiration was superior in higher temperature for zoysiagrass green and in lower one for bentgrass green. The differences of photosynthesis and LAI between before and after mowing were around 10%, and LAI existing in an actual green was around 2.0 in both type greens" |
