- Intervention effect Salinity inhibited shoot and root biomass production and individual leaf area in sweet basil already at 25 mM NaCl.
- Intervention effect Raising salinity from 1 to 100 mM NaCl reduced fresh herb biomass production by 63%.
- Intervention effect Raising salinity from 1 to 100 mM NaCl reduced dry herb biomass production by 61%.
- Mechanism The stress-induced reduction of foliage biomass came mainly from inhibition of leaf area development rather than reduced internode and leaf number.
- Intervention effect Cl and Na concentrations in leaves, stems and roots increased with increasing NaCl concentration in the solution.
- Observation Cl accumulation was highest in leaves, then stems, then roots.
- Observation Na was largely excluded from the leaves and preferentially accumulated in roots and stems.
- Intervention effect Salt stress increased the contents of essential oil and carotenoids in sweet basil leaves.
- Intervention effect Raising salinity from 1 to 130 mM NaCl caused a twofold increase in carotenoid concentration and in the percent of essential oil in fresh tissue.
- Intervention effect In the 1-75 mM NaCl range the stress-induced increase of the percent essential oil in tissue was about 50%.
- Intervention effect Oil production per plant was not reduced by salinity because the increased oil percentage compensated for the biomass reduction.
