Effect of Salt Stress on Cool-season Turfgrass Seed Germination

CHEN Mei-rong (Linyi Normal University,Linyi,Shandong 276005)  
To investigate the salt of the cool season turf grass seed germination,set NaCl,NaHCO3 single salt on turfgrass seed germination.The results showed that low concentrations of NaHCO3,NaCl salinity on ryegrass,kentucky bluegrass seed germination and germination rate did not significantly inhibit,NaCl than 0.09 mol/L or NaHCO3 than 0.06 mol/L,germination potential,germination rate decreased significantly;for festuca arundinacea seed germination and germination rate of inhibition was stronger than ryegrass and bluegrass.for NaHCO3 germination of three varieties,the germination rate was stronger than NaCl.The effect of NaHCO3 on the germination potential and the germination rates was stronger than NaCl.
