Abstract

Salinity is a major problem caused by the accretion of excess salts composites in the form of ions like sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+) and chloride (Cl-). The possible out-turns of the salinity on the morphology; physiology and biochemical variables of bismarckia palm (Bismarckia nobilis) were investigated in this study. The seedlings of bismarckia palm were grown in pots and periodically irrigated with various concentrations of NaCl solution to assess the various biological variables at the regular intervals. The experiment was performed by following the completely randomized design (CRD) and the results showed that the increased level of salt stress significantly decreased the shoot, length, fresh and dry weight. Conversely, the root length and fresh, dry weight were enhanced under higher salts concentration (150 mM of NaCl). However, there was no effect of stress on leaves parameters particularly for total number of leaves. Moreover, the chlorophyll contents were reduced with the increase of the NaCl concentration. Similarly, the antioxidants activities including SOD, POD and CAT were enhanced at maximum test dosage. Conclusively, it can be concluded that high saline condition of soil may hinder the morphological, physiological and biochemical statutes of bismarckia palm (Bismarckia nobilis).
