The present investigations was carried out for stone characterization, analyze the physico-chemical properties of media and to identify the best suitable media for germination using different polyembryonic rootstocks of mango during 2012-13 at Regional Horticultural Research and Extension Centre, Bengaluru. The studies revealed that, the significant variation was found in stone attributes (weight, length, breadth, circumference and volume). Based on germination test, the Olour rootstock showed better germination (earliest germination 21.33 days, minimum days for 50 per cent germination 31.78 days, higher germination percentage 43.78% and rate of germination 0.016) in compared to other rootstocks. Further, out of three media, the Cocopeat media showed better physical and chemical properties (pH 7.55, water holding capacity 216.04% and pore space 64.01%) and it was also observed that, cocopeat has been taken less time for germination initiation (20.78 days), 50 per cent of germination (33.67 days), maximum germination (48%) and rate of germination (0.016) compared to other media. Furthermore, the interaction effect between media and rootstock showed significant difference on germination behavior. Therefore, the Olour stones showed significant germination on Cocopeat media; hence the generated information could be utilized by nurseryman for getting maximum germination of rootstocks in a nursery.
