Salinity is one of the most important environmental factors
controlling plant growth and development. And
recognizing their biochemical and physiological changes
to salinity is necessary in order to reduce its negative
effects. Therefore, in order to study the effect of the
external application of sodium nitroprusside (SNP) and
Hydrogen Peroxide in order to reduce the negative effects
of salinity induced oxidative stress, the medicinal plant
was grown hydroponically. This experiment was based on
a factorial arrangement based on randomized complete
block design with two levels of salinity (0 and 50 mM
Sodium Chloride) and three levels of sodium nitroprusside
hree levels of solubility
Hydrogen Peroxide spraying (0, 2.5 and 5 mM) was
performed with three replications. After essential oil
extraction, the essential oil yield was calculated according
to its content in the plant; The extracted essential oils were
also measured by detection of secondary metabolites by
the GC-MAS device. The highest amount of essential oil
was obtained at a salinity level of 50 mM with external
peroxide. Also, according to the results, methyl chavicol,
linalool, and cadinol showed higher amounts than other
metabolites in the treatments. The amount of melkavicle as
the most important basil substance was affected by the
external use of SNP and its highest rate was observed in
the external appl
result, we can say that exogenous application of SNP and
H2O2 While positively affecting the accumulation of active
ingredient of basil reduces the oxidative stress caused by
salinity by increasing the accumulation of active
ingredients.
