Abstract:
Taking ‘Toyonoka’ strawberry as material, the effect of different nitrogen concentration with 0,40,80,120 mg/kg on photosynthetic pigments,maximum photosynthetic rate,nitrate reductase activity and soluble protein content of post-anthesis strawberry leaves were studied in greenhouse.The results showed that,chlorophyll content,maximum photosynthetic rate,nitrate reductase activity and soluble protein content of strawberry leaves during flowering period and fruit setting period increased with the rising nitrogen concentration,the nitrogen concentration at 120 mg/kg had the biggest promotion.While chlorophyll content,maximum photosynthetic rate,nitrate reductase activity and soluble protein content of strawberry leaves during fruit expending period,fruit coloring period and fruit ripening period first increased and then decreased with the increasing nitrogen concentration,the nitrogen concentration at 80 mg/kg had the biggest promotion.
