Abstract:

The present investigation was conducted at College of Agriculture, Vellayani during the year 2017-2018 to assess the effect of pre-sowing treatments, sowing positions and age of stone after extraction from the fruit on germination of mango. Mango stones of different age groups viz., freshly extracted stones, 10 and 20 days after extraction of pulp were soaked for 24 hours in aqueous solutions of GA3 (100 and 200 ppm), KNO3 (1 and 2 ppm), cow dung slurry, water and control (without treatments) and sown in flat and stalk end up (plumule up) positions in polythene bags. The freshly extracted mango stones which were soaked in 200 ppm GA3 solution and sown in plumule up position recorded the least number of days for initiation of germination (13 days) and 50 % germination (23 days), the highest rate of germination (0.74), seedling length (27.35 cm) and dry weight (10.70 g) whereas freshly extracted mango stones which were soaked in 100 ppm GA3 solution and sown in plumule up position recorded the highest germination (82.22 %), seedling vigour index -I (2142.03 cm) and seedling vigour index-II (791.48 g).
