摘要: 设置不同遮阴度0(CK)、30%、50%和70%处理, 考察其对草莓(Fragaria ananassa Duchesne)生长状况、光合特性和产量品质的影响。结果表明, 不同的遮阴度处理对草莓的光合特性和产量品质有明显影响, 遮阴度30%处理下草莓光合特性和产量品质达到最佳。在0(CK)和遮阴度30%处理下草莓光合日变化曲线为双峰型, 出现了“午休”现象;50%和70%遮阴度处理下为单峰型。草莓的净光合速率、蒸腾速率、气孔导度和胞间CO2浓度均随着遮阴度的增大呈递减趋势;草莓的光饱和点、光补偿点和暗呼吸均随着遮阴度的增大明显下降。草莓在弱光环境下对光能利用能力较强。

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
