The ‘Sulhyang’ strawberry recently bred in Korea accounts for more than 83% of the entire strawberry cultivation area in Korea. While the growth properties of strawberry are dependent on the cultivars, the growth properties of ‘Sulhyang’ have not been known abundantly. In the present study, to obtain the basic data about the growth properties of ‘Sulhyang’, the photosynthesis properties, which are the basis of material production, were studied by investigating the light-photosynthesis, temperature- photosynthesis, and CO2-photosynthesis curves.In addition, the photosynthetic responses of strawberries cultivated in seasons of different temperature environmental conditions were compared to apply the results to cultivation management. The optimal photosynthesis temperature of the ‘Sulhyang’ strawberry cultivar was as high as about 29℃, and the rate of photosynthesis was not greatly dependent on temperature. The light saturation point was 1,300μmolm-2s-1 of photosynthetic photon flux density(PPFD) at 25℃ of leaf temperature and at 400μmolmol-1 of CO2 concentration. The CO2 saturation point was 1,400μmolmol-1 (concentration in the atmosphere) or 930μmolmol-1 (concentration in the intercellular space) at 25℃ of leaf temperature and 1,300 μmolm-2s-1 of PPFD. The net photosynthesis rate at the light saturation point was measured from Leaf Nos. 1 to 5, and the result showed that the net photosynthesis rate was not dependent on the leaf position. The rate of dark respiration was higher in younger leaves. The rate of photosynthesis was generally higher in the strawberries cultured in the low-temperature season than in the high-temperature season, and the difference was significantly shown in the temperature curve. These results, which are greatly different from those of previous strawberry cultivars, may considerably contribute to the technological development of the ‘Sulhyang’ strawberry cultivation.
