C
admium (Cd) is an omnipresent non-nutrient heavy metal,
with a particular concern because of its high solubility,
mobility, and high phytotoxicity even at low concentrations as
well as its toxicity for human upon its entry into the food chain.
In this study, salicylic acid (SA) has been investigated as a pre-
treatment on Grand naine cultivar grown in vitro. Grand naine
explants were cultivated on MS medium supplemented with
different concentrations of SA (0, 0.5 and 1 mM), then these
explants transferred twice to MS medium supplemented with
varying concentrations of Cd (0, 50, 100, 200, 500, 1000 and
1500 μM CdCl₂) to examine the accumulation effect of Cd on
bananaexplants.AftertwosubculturesonCdmedium,wefound
out that adding SA at 0.5 mM had a significant positive effect
on vegetative growth such as; mortality, shoot multiplication,
plantlet height (cm), fresh and dry weight (g), total chlorophyll,
carotenoids and proline content. Moreover, the application of
0.5mMof SA to the plants treated with 500 μMCd reduced the
uptake of Cd by 15%. The results in this paper is expected since
SA is knowing as a hormone-like substance which has been
reported as an alleviator for abiotic and biotic stresses either in
vitro or in vivo cultures in many different plant species.
