Growth and development of date palm (Phoenix dactylifera L.) seedlings under drought and salinity stresses
The present investigation has been performed to evaluate date palm (Phoenix dactylifera L.) tolerance to
osmotic stress induced by polyethylene glycol (PEG) or NaCl during the early stages of plant
development. Two varieties Nakhla hamra (NHH) and Tijib widely cultivated in Mauritania were tested.
NHH showed increasing of epicotyl length, primary root length, secondary root number and proline
content when water deficit was induced by PEG. In contrast, on the basis of the same developmental
and biochemical characters, the Tijib cultivar was more tolerant in salinity stress. This difference of
cultivars’ behavior according the growth conditions is discussed.
