| 英文摘要 | A sand-culture experiment was conducted in four Open-Top-Chambers to assess the effects of O-3 on salinity-treated winter wheat. Two winter wheat cultivars, salt-tolerant Dekang961 and salt-sensitive Lumai15, were grown under saline (100 mM NaCl) and/or O-3 (80 +/- 5 nmol mol(-1)) conditions for 35 days. Significant (P<0.05) O-3-induced decreases were noted for both cultivars in terms of gas exchange, relative water content, growth and biomass yield in the no-salinity treatment Significant (P<0.01) corresponding decreases were measured in Dekang961 but not in Lumai15 in the salinity treatment. Soluble sugar and proline contents significantly increased in both cultivars in combined salinity and O-3 exposure. O-3-induced down-regulation in the gradients of A-C-1 and A-PPFD response curves were much larger in Dekang961 than in Lumai15 under saline conditions. Significant (P<0.05) interactions were noted in both salinity x cultivars and salinity x O-3 stresses. The results clearly demonstrated that O-3 injuries were closely correlated with plant stomatal conductance (g(s)); the salt-tolerant wheat cultivar might be damaged more severely than the salt-sensitive cultivar by O-3 due to its higher gs in saline conditions.
