Abstract
Studies on the photosynthetic characteristics of two strawberry varieties (Baojiaozaosheng and Shuofeng) under shading showed that the photosynthesis rate decreased by 20% and 47%, when the apparent quantum efficiency increased by 13% and 8%, respectively. The chlorophyll content was enhanced slightly, while the insoluble protein content in leaf decreased drastically. The results also showed that the PSII activity decreased by 22.5% and 53.7%, and the activity of Rubisco, the key enzyme of Calvin cycle, decreased by 19.6% and 35.5%, respectively. The reason of photosynthesis rate descent in light saturation point was also discussed.
