Abstract

An experiment on “Effect of foliar application of plant growth regulators on quality of acid lime (Citrus aurantifolia Swingle) Kuliana local’’ was carried out during spring season of the year 2019-20 and 2020-21 at Horticultural Research Farm, Department of Fruit Science and Horticultural Technology, Orissa University of Agriculture and Technology, Bhubaneswar, Barimunda. The experiment was laid out in Pooled Randomized Block Design with fifteen treatment and replicated thrice. Results evaluate the suitable growth regulator in terms of quality parameters. Results revealed that different types of growth regulators (2,4-D at 10 ppm and 20 ppm) and GA3 (GA3 at 50 ppm and 100 ppm) and NAA (NAA at 100 ppm and 200 ppm) and SA (SA at 100 ppm and 200 ppm) and Spermidine (Spermidine at 0.01 ppm and 0.5 ppm) and Putrescine (Putrescine at 0.01 ppm and 0.5 ppm) and Brassinosteroids (Brassinosteroids at 0.1 ppm and 0.5 ppm) and control (water spray) on quality of acid lime kulianalocal. The biometrical observations on various quality attributes were recorded in same seasons in both years. The best fruit quality has been found based on the effectiveness of growth regulators since variations in growth regulators have a significant impact on fruit quality. Brassinosteroids showed the best effect for TSS (7.17 oBrix), Acidity (6.83 %), total sugar content (0.61 per cent), reducing sugar content (0.41 per cent), ascorbic acid (36.35 mg per 100 ml of juice), chlorophyll content (33.03 mg/100 g), flavonoid content (119.91 mg/100 g) and protein (0.82 mg/100 g) with the other treatments including the untreated fruits in both years of the study. Our results illustrated that the BR was gave best results in quality attributes for Kuliana lime.

Keywords

Acid lime, plant growth regulators, biochemical quality, sugars, acid

Conclusion

Based on the study, it can be concluded that plant growth regulators have become powerful tools to modify several physiological process in plants which are extensively and profitably used in horticultural crops. Among the growth regulators, Brassinosteroid @ 0.5 ppm showed best results interms of highest percent of juice content, TSS, total sugars, reducing sugars, ascorbic acid, chlorophyll content, flavonoid content, protein content and acidity.
