[Changes in solute content of different tomato genotypes under salt stress].


Two wild tomato species Lycopersicon peruvianum LA111, Lycopersicon pennellii LA716 and two cultivars "Xianfeng 98-7", "Jiaonong No.1" with different salt tolerance were treated with NaCl 150 mmol/L, and to measure the inorganic ions Na(+), K(+), Ca(2+) contents and the organic compounds free proline, soluble sugar contents. The results indicated that under salt stress, the wild species accumulated much Na(+) in young leaves, while cultivated species produced and accumulated much free proline and soluble sugar in young leaves, and Na(+) was mostly distributed to old leaves. So it can be seen that there are marked differences between wild species and cultivars in producing and accumulating these solutes under salt treatment. They adapt to salt stress through different salt tolerance mechanisms.
