Abstract
Effect of salinity on growth and biochemical composition of two varieties of okra 'Ahwazi green' and 'white Dzfvly'dr greenhouse factorial experiment in a completely randomized design with four replications was the Grdyd.tymarhay salinity control (distilled water), 25, 50 , 75, 100 and 125 mM sodium chloride applied in four-leaf stage and continued until harvest. In this study, stem diameter and height characteristics, shoot fresh and dry weight, leaf area, chlorophyll content, sodium and potassium of leaves, flowering time, number of flowers and fruits, percentage of first grade fruits and total weight of fruits were measured. The results showed that Dezfuli white cultivar showed better tolerance to salinity. Sodium chloride significantly increased sodium and decreased potassium in leaves. The results also showed that salinity stress treatment reduced stem diameter and height, shoot fresh and dry weight, leaf area, leaf chlorophyll content, number of flowers and fruits, percentage of first grade fruits and fruit weight and delayed flowering time. However, okra plant was able to produce high quality and quantity fruit up to 25 mM salinity stress.
