| Popis: | Purpose: Lime (Citrus aurantifolia) is a lucrative crop with a year-round demand. However, seasonality in fruiting causes market glut. Therefore, potential of gibberellic acid (GAs), brassinolide (BL) and salicylic acid (SA) as preharvest foliar sprays on widening narrow harvest window alongside improved fruit quality were studied. Research Method: Experiments were performed on five-year-old 30 lime trees of cv. Monaragala Local. Trees were treated with aqueous solutions of GA (12.5, 25.0, 37.5 mg L-1), BL (0.5, 1.0, 1.5 mg L-1) and SA (1, 2 and 3 mmol L-1) at 4-5 mm and 12-15 mm diameter stages of fruit growth. Findings: Two higher doses of GA (25.0 and 37.5 mg L-1) delayed lime fruit maturity by ≈25 - 40 days while the highest dose of BL (1.5 mg L-1) and the lowest dose of SA (1.0 mmol L-1) advanced fruit maturity by ≈75-80 days significantly (p |
