چکیده
basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rate, the amount of malondialdehyde (mda) and proline , also the changes enzymes activity in some of antioxidant enzymes in leaves. in order to investigate the interaction of salinity and nano fe-chelate spraying on basil, an experiment as a factorial in completely randomized block design with five levels of salinity (0, 25, 50, 75 and 100 mm nacl) and four level of nano fe-chelate (0, 2, 5 and 10 grams per liter) with three replications was conducted. results indicated that photosynthetic pigments and growth parameters significantly decreased under salt stress compared with the control, but the use of nano fe-chelate in different levels of salinity improve and enhance the performance of basil compared to control and salt stress without iron. in addition, study of physiological characteristic showed salinity due to increase of mda, proline and enzymatic activity of catalase and peroxidase, that using of nano fe-chellat made decreasing in mda content and increasing of proline and enzymatic activity of catalase and peroxidase in comparison to control sample and sample without fe. the results showed that the use of nano fe_chellat improves and enhances basil plant growth under salt stress.
