Abstract
To explore the quality rootstock which impart better stionic establishment of the mango seedlings, we studied the comparative effect of scion and rootstock using three mango scion varieties (Sindhri, Chaunsa and Neelum) grafted on three rootstocks i.e. Ratam, Pado and Sindhri. Parameters including seed germination (%), seedling height (cm), leaves seedling rootstock-1, seedling vigor index (SVI), fresh biomass of shoot and roots (g), dry biomass of shoot and roots (g), chlorophyll content (rg), rootstock diameter (mm), scion diameter (mm), stionic ratio, leaves graft-1 and sturdiness quotient were studied. Results showed the best seed germination (88.33%), seedling vigor index (5158.74), and sturdiness quotient (3.89) in Pado rootstock. However maximum fresh biomass of shoot (20.67 g), fresh biomass of roots (16.2 g), dry biomass of shoot (12.65 g), dry biomass of roots (8.33 g) and scion diameter of the rootstocks were observed in Sindhri rootstocks. Regarding grafting data, the best stionic ratio (0.93) was observed from the scion and rootstock combination of Neelum and Pado rootstock. It was concluded that Pado rootstock performed better in terms of seedling rootstock and for successful stionic establishment of the mango seedlings
