Genotypic difference in salinity and water stress tolerance of fresh market tomato cultivars.

摘要

The physiological response and tolerance of four fresh-market, cultivated tomatoes (Lycopersicon esculentum cultivars F121, F144, Fireball and Patio) to water stress and salinity were determined. Under salinity, ion accumulation, osmotic potential and dry matter production were highly correlated. No such correlation was found under water stress. No correlation between plant tolerance and accumulation of proline could be determined. Based on the growth parameters, ion accumulation and osmotic potential of young leaves, salt tolerance of the cultivars studied was in the following descending order: Fireball > Patio > F121 > F144.
