Abstract

Abstract: The growth, photosynthetic characteristics, yield and quality of strawberries （Fragaria ananassa Duchesne） were studied under different shading conditions of 0 （CK）, 30%, 50% and 70%. The results showed that different shading degrees had obvious effects on the photosynthetic characteristics and yield and quality of strawberry. Under 30% shading degree, the photosynthetic characteristics and yield and quality of strawberry were the best. Under the condition of 0 （CK） and 30% shade, the diurnal curve of strawberry photosynthesis was bimodal, showing the phenomenon of “noon break”, while under 50% and 70% shade, it was single peak. The net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO₂ concentration of strawberry decreased with the increase of shading. The light saturation point, light compensation point and dark respiration of strawberry decreased with the increase of shade. Strawberry has a strong ability to utilize light energy in low light environment.

Key words: strawberry（Fragaria ananassa Duchesne）, shade, photosynthetic characteristics, yield and quality
