Effect of Proline on Growth and Nutrient Uptake of Simmondsia chinensis (Link) Schneider under Salinity Stress

摘要: BACKGROUND AND OBJECTIVE Simmondsia chinensis (Link) Schneider grows as an important economic and medical plant in deserts. It suffers from salt stress during the first period of growth despite having to endure it after advanced age. More than 30% irrigated lands worldwide are destructively impacted by stress, which enormously influences productivity several crops worldwide. Proline (Pro) aggregation has been correlated with tolerance. This treatise was conducted evaluate impact Pro on negative effects salinity. MATERIALS METHODS In this experiment, sodium chloride (NaCl) (5 10 dS m-1) treatments (10 20 mM) were examined then parameters, relative water content (RWC), chlorophyll inorganic ion contents jojoba determined. RESULTS Salt significantly minimized parameters (i.e., height, branch number/plant, leaf number/plant dry weight), RWC, N+ K+ contents, whereas Na+ Cl- showed opposite manner. CONCLUSION Contrariwise, when applied at mM, adverse previous mitigated; mM treatment superior compared treatment.
