Savory plants were treated with different concentrations of
NaCl. Plants were grown under controlled environment and harvested
after 42 days for measurements of biochemical and physiological
parameters. The essential oil of dryed aerial parts of treated plants
were isolated and analyzed with GC/MS. The main essential oil compounds
were determined as carvacrol (55.37%) and g-terpinene (32.92%) in
control plants. In NaCl treated plants, with increasing NaCl, carvacrol
content increased and g-terpinene decreased. In all the plants treated
with NaCl, growth parameters, pigments contents and photosynthetic rate
were decreased, while, proline and soluble sugars contents increased.
Our results indicated that with increasing salinity, carvacrol amount
increased which can be considered for medical usages.
