Abstract

The research was conducted during the autumn season 2020-2021 in Al-Mahnawiya area, Babylon province, to study the effect of treating eggplant seeds with UV rays and the growth regulator gibberellin GA3 on growth indicators and yield of eggplant. The Randomized Complete Block Design R.C.B.D was used, with three replicates and two factors, the first factor included ultraviolet (UV) rays, and with three periods (4,2,0 hours) and symbolized by the symbol (A3,A2,A1), and the second factor was the growth regulator, gibberellin GA3. And in four concentrations (600,400,200.0 mg.L-1) and symbolized by (B4, B3, B2, B1),The results of treating the plant with ultraviolet rays showed significant differences in some traits, where the control treatment achieved the irradiation period (0 hours) the highest rate of the number of fruits per plant, which reached (14.27 fruits. Plant-1), Compared with the radiation period (4 hours), which gave the lowest rate of (12.76 fruits. Plant-1), and the highest average of dry matter of fruits, which reached (9.73%), compared to the radiation period (2 hours), which gave the lowest rate of (8.87%). While the radiation period (4 hours) was significantly excelled in recording the highest rate of chlorophyll pigment, as it reached (55.0 mg.100 g-1 fresh weight). Compared to the control treatment, which recorded the lowest average of chlorophyll pigment (43.4 mg.100 g-1 fresh weight). The treatment with gibberellin GA3 recorded significantly excelled in all studied traits, where the concentration (600 mg.L-1) achieved the highest average (number of leaves, leaf area, number of branches, weight of the fruit) reached (22.36 leaves.plant-1), (4354 dm2. leaf-1), (4.333 branches. plant-1), (0.150 kg. fruit-1). While the concentration of gibberellin (400 mg. L-1) significantly excelled in the average number of fruits per plant, and the highest rate was recorded at (14.68 fruits. g-1 fresh weight). The concentration of gibberellin (200 mg.L-1) was significantly excelled on the average content of chlorophyll in leaves, and the highest average was (54.4 mg.100gm-1 fresh weight). The effect of interaction between UV rays and gibberellin significantly on all studied traits. Where the interaction treatment achieved the radiation period (2 hours) and the concentration of gibberellin (600 mg.L-1) the highest rate (number of leaves, leaf area, number of branches) reached (23.47 leaves. plant-1, 5436 cm2.leaf-1, 4.533 branches. Plant -1 respectively, and the interaction treatment recorded the radiation period (0 hours) and the gibberellin concentration (400 mg.L-1) the highest average of the number of fruits reached (16.02 fruits.plant-1), and the interaction treatment recorded the radiation period (0 and 4 hours). The concentration of gibberellin (600 mg.L-1) had the highest average fruit weight amounted to (0.152 kg.fruit-1), the interaction treatment recorded the radiation period (4 hours), and the gibberellin concentration (200 mg.L-1) had the highest rate of chlorophyll pigment reaching (76.0 mg). 100 gm-1 fresh weight), the interaction treatment recorded the radiation period (4 hours) and the gibberellin concentration (400 mg.L-1) the highest average of carotene pigment was (0.416 mg-100 g-1 fresh weight), the comparison treatment recorded the radiation period (0 hours and gibberellin 0 mg. L-1) had the highest rate of dry matter of fruits (11.03%).
