Effect of growing media and GA3 on seed germination, growth and survival of Acid lime (Citrus aurantifolia Swingle) var. Kagzi seedling

Abstract

A field experiment was carried out at Fruit Research Station Imalia, Department of Horticulture, College of Agriculture, JNKVV Jabalpur to assess the effect of growing media and GA3 on seed germination, growth and survival of Acid lime (Citrus aurantifolia Swingle) var. Kagzi. The treatments comprised five levels of seeds soaking in GA3 solutions and four different growing media were arranged thrice in Randomised Block Design. It was observed that the seed soaked with 150 ppm concentration of GA3 and growing media comprising soil + slurry enrich with Azotobacter significantly improve the parameters with regard to day taken to initiate germination, to attained 50% germination, germination at 30 days after sowing, height of shoot, stem girth, number of leaves, total length of seedling, fresh weight of shoots, dry weight of shoots, fresh weight of roots, dry weight of roots, length of taproot, number of secondary roots, seedling vigour index I, seedling vigour index II, survival percentage of seedling. The higher value of physiological parameter were also recorded with seed soaked with 150 ppm concentration of GA3 and growing media comprising soil + slurry enrich with Azotobacter individually.
