degree of discrimination against 13 C is determined largely by intercellular CO 2 concentration, which is controlled by the ratio of A to g wv ( Farquhar et al., 1989 ). Stable carbon isotope discrimination may be used to estimate WUE during the

ripeness, the O 2 level was higher and CO 2 level lower at all storage temperatures. During storage, concentrations of O 2 and CO 2 changed rapidly in the first 7 d and subsequently showed small changes over time regardless of storage temperatures

experiment. A portable photosynthesis analysis system Li-6400 XT (LI-COR Biosciences, Lincoln, NE) was used to determine the P n , g s , transpiration rate (T r ), and intercellular CO 2 concentration (C i ) between 8:00 am and 10:00 am . The system

intercellular CO 2 concentration (C i ) were obtained under light conditions determined by each shade treatment. All of the photosynthesis measurements were performed on outer fully expanded leaves sampled on branches located in the middle of the canopy. The

conditions could be partly due to stomatal limitation. Indeed, mean intercellular CO 2 concentration (C i ) declined from 320 μmol CO 2 /mol in control plants to 283 μmol CO 2 /mol in treated vines after 5 d of saturation at the bud elongation stage

included four O 3 treatments plus a control. The four O 3 treatments were a combination of O 3 concentration and treatment time as follows: 1) low O 3 , day-only, 2) high O 3 , day-only, 3) low O 3 , day + night, and 4) high O 3 , day + night (i

. Intercellular CO 2 concentration in leaf cell increased with increase in salinity (r = 0.72, P ≤ 0.01, but stomatal conductance, transpiration and net CO 2 assimilation were not significantly affected by salinity. Intercellular CO 2 concentration decreased
