Abstrakt
As an important economic plant, Lycopersicon esculentum (Mill.) faces salinity stress
from germination to all growth stages. The aim of this study is to ride salt-induced agriculture
difficulties of tomato by applying different chemical seed priming: ascorbic acid (ASA),
potassium nitrate (KNO3) and calcium nitrate (CaNO3) during two time periods which are 24 and
48 hours. In the current case, the seeds were pre-treated with previously mentioned chemicals for
varying periods of time before germination in a salt solution (100 mM NaCl). The treatments
were replicated three times. For no primed seeds, salt treatment decreased germination parameters
as well as seedling growth parameters (fresh weight, epicotyl and root length and chlorophyll
content). Different chemical seed priming alleviated the salt harmful effect on germination and
growth parameters. In saline conditions, the priming agents, had more significant effect in
comparison with normal conditions. Significantly, the treatment including CaNO3-48-h priming,
had high efficacy in promoting germination and plant growth and is associated with reduced
levels of leaf proline and malondialdehyde (MDA) content.
