Abstract/Contents: | "The diurnal variation of photosynthesis of 5 wild Dichondra repens Forst. in southwest of China were measured by a Li-6400 portable photosynthesis system, and the differences of photosynthesis characteristic were compared. Results showed: 1) With natural illumination, the net photosynthetic rate(Pn) diural variations of 5 accessions showed a double peak curve with the 1st peaked at 12:00 and the 2nd at 16:00,and there was typical midday depression.2) The diurnal mean transpiration rate (Tr) value of unit area and the diurnal mean value of available water use efficiency(WUE) of 5 accessions were significantly different.The diurnal mean Tr value of SD10 was far more higher than the others, and it was strong transpiration material.The WUE of SD11 was the highest which can produce more biomass than the others when given the same amount of moisture.The adaptations to light of 5 wild D. repens were different, GD03 with a high light saturation point[1 051 μmol/(m2·s)] and a low light compensation point [28.2 μmol/(m2·s)] was resistant to shade, and adaptive to the strong solar radiation. It was chosen for further study as an outstanding turf grass germplasm resource with excellent turf-used characteristics." |
