(%lpf;) jlj TixZ7 1 4 Summary A total of 14 grapevine accessions (8 Vitis species and 6 cultivars ) were examined in order to elucidate the relationships between photosynthetic activity and light intensity, Photosynthetic rate (PO, mgcoz. dm /hr) of grapevine leaves increased in accordance with the level of light intensity. Although great differences were observed within genus Vitis, light saturation point (S.P) and light compensation point (C.P) generally ranged from 2 to 4klx and from.2 to 2. klx, respectively. In general, dark respiration (D. R, mgcon/dm ihr) and C. P were higher in high temperature than in low one. Until 2 klx of light intensity, transpiration (Tr, ghao/dm /hr) and stomata1 conductance (gl, cm/set) linearly increased in consistent with the increase of intensity, and thereafter increased progressively. Water use efficiency (Po/Tr ratio, mgcos/ghzo) increased linearly until 2 klx of light intensity. The Po/tr ratio was low in high temperature. Intercellular CO2 concentration (Ci, ppm) decreased with the increase of light intensity. Compared with grapevine accessions which are grown in low latitudes, those in high latitudes showed the low PO under high temperature toget her with the low S. P, C. P, Tr and gl. In the cultivars eventhough having the same parentage, large varietal differences in the PO, Tr, gl, and Po Tr ratio were found.
