Abstract:
It has been shown that salicylic
acid (SA) acts as an endogenous signal
molecule responsible for inducing biotic and
abiotic stress tolerance in plants. The effect
of three application methods (Soil, Foliar
and Priming) and four salicylic acid
concentrations (0, 0.1, 0.5 and 1.0 mM) on
chlorophyll a, b and total chlorophyll,
carotenoids, proline, protein and soluble
sugars of NaCl (4 ds/m) stressed white bean
(Phaseulus vulgaris L.) was investigated.
The results showed that the effect of applied
concentrations and application methods on
chlorophyll a and total chlorophyll, proline,
protein and soluble sugars were significant.
The interaction of concentrations and
application methods used was significant on
protein, proline and soluble sugars.
According to the results, the greatest impact
was belonged to the soil treatment which
was not significantly different from priming.
Among applied concentrations, the
concentration of 0.1 and 0.5 mM were the
most effective and the concentration of 1
mM was not significantly different from the
control.
