Abstract:
An investigation entitled “Effect of storage period and growing media on seed germination and physiological attributes of acid lime seedlings (Citrus aurantifolia Swingle) cv. Kagzi†was conducted during the year Kharif - 2016 at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. The treatments comprised four levels of storage period (S) viz., S1- 0 day after seed extraction, S2- 15 days after seed extraction, S3- 30 days after seed extraction and S4- 45 days after seed extraction with three levels of growing media (M) viz., M1- Soil + Vermicompost (1:1), M2- Soil + Cocopeat (1:1) and M3- Soil + FYM (1:1). The experiment was laid out in a Completely Randomized Design (Factorial) with twelve treatment combinations and three repetition. Sowing of seed immediately after extraction observed minimum number of days (22.33) for 50 percent germination, maximum germination percentage (70.50) at 45 DAS and speed of germination (13.38) with maximum vigour index- I (3591.50), seedling vigour index- II (321.41) at 120 DAS and relative growth rate at 60-90 and 90-120 DAS (1.54 and 4.62 g/day). Growing media M2 recorded minimum days (30.33) for 50 percent germination, maximum germination percentage (63.27) at 45 DAS and speed of germination (12.47). While, at 90-120 DAS growing media M1 recorded maximum relative growth rate (2.55 g/day) with seedling vigour index- I (2097.18) and II (157.73) at 120 DAS. Treatment combination S1M2 recorded minimum days (18.00) for 50 percent germination with maximum germination percentage (74.55) at 45 DAS. At 60 DAS treatment combination S1M2 recorded seedling vigour index- II (44.81). At 90 DAS treatment combination S1M1 recorded the highest seedling vigour index- I (2777.90). Whereas, treatment combination S1M1 recorded maximum relative growth rate at 60-90 and 90-120 DAS (1.65 and 5.50 g/day) and seedling vigour index- II (388.73) at 120 DAS.
