| Abstract: | The seeds and seedlings of Festuca arundinacea Schreb were treated with NaCl(50,100,200,300 mmol/L)and Na2CO3(5,10,15,25 mmol/L)respectively,and the gernmination potential,gernmination rate,root length,seedling height,fresh weight,chlorophyll content,root activity,membrane permeability and MDA content were determined.The results showed:compared with the control,with the NaCl concentration increased,the germination potential,germination rate,root length of F.arundinacea decreased,leaf membrane permeability a... |
