Abstract

The effect of different salinity levels (up to 120 mM NaCl) on germination, Seedling growth, dry matter and some
related metabolic parameters of sweet basil tOcimum basilicumi was studied. During germination it tolerated salinity
up to 60 mM NaCI. However, seedling growth and dry matter production were decreased by NaCI greater than 40 mM
NaCI. Soluble carbohydrate and proline concentration of seedling increased with increase of salinity. However, soluble
protein and amino acids were decreased by salinity. In long term (36 days) experiment, growth decreased with increasing
salinity levels, except at 5 and 10mM NaCl where growth was increased. Water content in the whole test plant increased
at 5 mM NaCI and decreased as salinity increased to 50 mM NaCI. These results may lead to the conclusion that, sweet
basil is a medium tolerant crop and is considered as glycophyte.
