Abstract :
In order to study the effect of sodium chloride salinity on flowering of eggplant varieties grown in the open air, a research was conducted in a completely randomized design with 10 replications. Salinity levels were used in seven concentrations of 0, 10, 20, 40, 60, 80, and 100 mM sodium chloride. The amounts of sodium chloride were added to the irrigation water (219 µmho.cm-1). Three varieties of eggplant seedlings (Jahrom locally, Dezful slender and sweet Hindi), were prepared and planted in plastic bags containing 9 kg of dominant cultivation soil of Khonj zone. Salinity treatments were followed for 5 months. Results showed that salinity generally reduced the number of flowers per plant compared to the control treatment and has delayed the flowering time but has no significant effect on the number of open flowers. Among studied cultivars based on considered characters the variety of Jahrom locally was evaluated as a more salinity tolerant and the variety of Dezful slender as the most sensitive one.
