Abstract:
The present experiment was carried out inside the shade net house (Horticulture nursery) of ICAR, KVK- Vijayapura-1 to find out the effect of gibberellic acid (GA3) on seed germination, seedling growth and its vigour of Indi’s Kagzi Lime. Six treatments were employed viz., T1- control, T2 (50 ppm GA3), T3 (100 ppm GA3), T4 (150 ppm GA3), T5 (200 ppm GA3) and T6 (250 ppm GA3) and each treatment were replicated for three times. All treatments significantly performed better as compared to control. According to the results obtained, after 60 days of sowing the maximum seed germination (94.57%) with minimum number of days taken for seed germination (21 days) was observed in the treatment of T6 i.e., 250 ppm gibberellic acid pre sowing seed treatment. Further, maximum seedling length (26.23 cm), maximum number of leaves (10.33), higher length of primary shoots (12.17 cm) and maximum number of secondary roots (23.33) were also observed in the pre sowing gibberellic acid seed treatment of T6 (250 ppm). Therefore, pre-sowing treatment of Indi’s Kagzi Lime seeds with 250 ppm GA3 may be recommended to the farmers than other gibberellic acid concentration to enhance seed germination percentage, rate of growth and Vigournes of seedlings leading to the production of vigorous plants which can be utilized for better nursery development, rootstock studies, commercial citrus cultivation as well as crop improvement programme.
