Studying the Response of Anethum graveolens L. to the Stress of Salinity and Foliar Spray with Alhagi Maurorum Aqueous Extract

Abstract

Background Weed infestation and salinity are both biotic and abiotic stresses that are highly present in the Basrah governorate in Iraq and widely influence crop growth Methods The present work was conducted to evaluate the effect of salinity at (0, 6, 12 dS/m) and aqueous extract of Alhagi maurorum at (0, 3 g/L) on growth and biochemical parameters as well as phytocomponents of Dill plant Anethum graveolens L. Results Results revealed that growth parameters and photopigment content increased with salinity at 12 dS/m and reduced with Alhagi maurorum aqueous extract. Besides that, carbohydrate content was reduced with both stresses, and proline content increased with Alhagi maurorum aqueous extract. GC-MS chromatogram of Anethum graveolens methanolic extract displayed high alteration in phytocomponents quantity post salinity and camelthorn extract treatments. Conclusion Current work inferred that the Dill plant has high tolerance properties to salinity contrary to weed infestation stress. Stresses combination declined growth parameters and reduced metabolite content of Dill plants.
