Abstract:
Abstracts: In order to understand the salt tolerance of Tall Fescue L., Poa pratensis L.and Lolium Perenne L.,8 different varieties, Festuca arundinacea L.(Barlexas, AridⅢ, Sunboy), Poa pratensis L.(Nassau , Bluechip, Merit)and Lolium Perenne L.(Prime,Focus)had been treated by nutrient solution in different concentration of NaCl. The results showed that: the critical concentration of salt of Poa pratensis L. was 200 mmol / L, the critical concentration of salt of Tall Fescue L. and Lolium Perenne L.was 150 mmol / L ; salt-tolerance of the differences: Bluechip was the best, Prime was the worst. The related leaf microstructures have been observed also, that included bulliform cell ,Vascular, Epidermic cell,stomatal apparatus,the results indicated: the capacity of salt tolerance of Poa pratensis L.was due to its microstructures similar with other salt-tolerant plants. Key words: turfgrass;salt resistance;leaf microstructure
