Effects of Combined Stresses of Salinity (NaCl) and Heavy Metal (NiCl2) Levels on Seed Germination and Growth of Citrullus colocynthis l.

Salinity and heavy metal stresses are a great hindrance to the germination development of plants. Nickel (Ni) is an indispensable micronutrient for plants at low concentrations. However, proficiency depends upon plant types. Citrullus colocynth medicinal cucurbit weed. The contemporary target study appraise influence combined by varying concentrations sodium chloride nickel on germination, morphology, biochemical ions, physiology C. colocynth. Germination percentage, root length, shoot fresh weight, dry number leaves, Na+, K+, Ca++, Cl-, Ni+, chlorophyll b, proline, SOD CAT were measured with nine levels (100 mM NaCl + 50 uM NiCl2), (200 (400 100 +100 200 NiCl2) +200 NiCl2). This experiment was conceded out in completely randomized design four replications. a, b decreased increasing stress while Proline, SOD, increased levels. species has positive morpho-physiological response under low(100mM NaCl, moderate (200mM combinations salt metals tolerance observed high-stress levels(400mM It concluded that this can be recommended phytoremdiation against stresses.
