Abstract

Effect of Shiara, Kainth large fruited, Kainth small fruited, Patharnakh cuttings and Sucker rootstocks along with inter-stock were evaluated for their effect on various vegetative characteristics of pear cv. Punjab Beauty. The overall minimum rootstock, inter-stock and scion girth was in Patharnakh cutting/Patharnakh/Punjab Beauty treatment among the triple combinations, while Sucker/Punjab Beauty recorded the lowest values both for rootstock and scion girth among double combinations. Combination of Patharnakh cutting/Punjab Beauty recorded maximum plant height, plant spread and tree volume. Leaf size and number of stomata were maximum in Sucker/Sucker/Punjab Beauty combination. The combinations of Shiara/Patharnakh/Punjab Beauty; Shiara/Punjab Beauty; Kainth large fruited/Patharnakh/Punjab Beauty; Kainth large fruited/Punjab Beauty; Patharnakh cutting/Patharnakh/Punjab Beauty and Patharnakh cutting/Punjab Beauty resulted into a smooth graft union. The results show great variability among different combinations. The combinations of Sucker/Sucker/Punjab Beauty and Sucker/Punjab Beauty have produced dwarf plants. These combinations will be further critically examined for their flowering and fruiting behaviour.
