Evaluating the impact of growth regulators on the early growth stages of acid lime seedlings (Citrus aurantifolia Swingle) cv. PDKV lime

Abstract

The present investigation was carried out entitled “Evaluating the Impact of Growth Regulators on the Early Growth Stages of Acid Lime Seedlings (Citrus aurantifolia Swingle) Cv. PDKV Lime” was carried out at All India Coordinated Research Project on fruits, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during the years 2020-21 and 2021-22. The effect of different growth regulators viz., combination of gibberellic acid, 6-benzyl adenine, brassinolide, and urea were used to treat the seeds of kagzi lime and further observation were taken from 60 DAS. The experiment was laid out in Randomized block design followed by pooled over-season analysis with fourteen treatments, including a check treatment, these treatments were replicated three times. The treatments included variations in concentrations. The results indicated significant variations among the treatments under shade net conditions the maximum plant height (32.02 and 94.81 cm), Number of leaves/per seedling (55.17 and 93.22), Number of branches/seedling (5.47, and 6.58) at 180 and 240 DAS. Similarly, fresh weight of seedlings (50.22 g) and dry weight of seedlings (25.84 g) were significantly maximum recorded with treatment T13 (GA3 50 ppm + 6 BA 25 ppm + Brassinolide 2 ppm).
