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.
