Abstract:

The experiment was conducted in open field condition during summer season of 2015 to investigate the effect of salicylic acid on flowers patterns and yield of Squash grown under open field conditions. Squash seedlings were treated with salicylic acid as irrigation or foliar application at different concentrations (0.25 – 0.50 – 0.75 – 1 mM). The experiment was completely randomized experimental design with 10 plants for each treatment and 3 replications. Results indicated that both application methods of salicylic acid have a positive effect on squash plants compared with control. The (1 mM) concentration of salicylic acid in both application methods (R1, F1) significantly increased the number of female flowers and total flowers/plant, as well as fruits number, fruit weight, mean plant yield and total yield, and decreased the number of male flowers. Also, foliar application treatments showed more positive results than irrigated treatments, especially within low salicylic acid concentration treatments (R0.25 and R0.50) which had not significant effect on the studied characters compared with control plants. Application of salicylic acid improved the yield contributing factors that resulted in significant increase in squash fruit yield.
