Abstract:
The present investigation entitled “Studies on the different concentration of GA₃ and media for seed germination of Acid lime (Citrus aurantifolia Swingle) under protected structure.” Was carried out during the year 2020-21. The experiment was conducted in completely randomized Design comprising of 13 treatments and 3 replication. The treatment consists of three concentrations i.e. 30 ppm, 60 ppm & 90 ppm of Gibberellic acid for 12 hours and have been used to different media (M₁) Soil, Sand, FYM, (M₂) Soil, Sand, Vermicompost, (M₃) Soil, Sand, FYM, Cocopeat and (M₄) Soil, Sand, Vermicompost, Cocopeat. The study revealed that growth parameters of Seed and physical parameters of growth in plants significantly affect of the seed germination of Acid lime seed. The seed germination was found to be highest in 90 ppm for 12 hours of GA₃ recorded significantly highest germination percentages, rate of seed germination, Number of shoots per plant, Number of leaves per plant and height of plants, fresh and dry weight of shoots (g), length of tap root (cm), average number of secondary roots and fiberous roots, survival percentage of plants and number of days to be ready for planting of sapling.
