Abstract: The present investigation was undertaken to assess the correlations between pre-sowing treatments, sowing positions and age of stone after extraction from the fruit on germination of mango cv. Kotookonam Varikka. 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 positions. The correlation coefficients indicates the presence of inherent association between various characters. The study revealed that the Seedling Vigour Index –I had very high positive and very dependable relationship with germination percentage (r=0.988**) and seedling length (r=0.974**) whereas Seedling Vigour Index-II had very high positive, significant correlation and very dependable relationship with seedling length (0.931**) in case of stalk end up method over the flat method of sowing.
