Abstract: Taking strawberry (Fragaria ananassa cv.Fengxiang) as material, two kinds of photorespiration inhibitors (NaHSO₃ and INH) at different concentrations were sprayed onto the leaves of strawberry during the flowering season.The results showed that NaHSO₃ (100 mg/L) and INH (0.5 mg/ml) could increase the leaf area, the chlorophyll content, and the photosynthetic rate.Meanwhile, the percentage of fertile fruit, single fruit weight, content of sugar and soluble solids increased significantly after spraying NaHSO₃ and INH.

Key words: strawberry, NaHSO₃, INH, yield, quality

摘要： 以"丰香"草莓为试材,在花期喷施不同浓度的光呼吸抑制剂NaHSO₃和异烟肼。结果表明,喷施一定浓度的NaHSO₃(100 mg/L)和异烟肼(0.5 mg/ml),可增加草莓植株叶面积、叶绿素总量和光合速率;同时可提高坐果率,增加单果重和产量,果实总糖、可溶性固形物含量也显著提高。
