Studies on the efficacy of IBA and NAA on clonal propagation by cutting in low chilling pear rootstocks

Abstract

Studies were conducted on the extent of success of clonal propagation of pear rootstock species viz. Mehal and Patharnakh cuttings by applying lanolin paste of IBA and NAA levels and their combinations at the base of 15–20 cm long cuttings obtained from five years old mother trees. Survival of cuttings in Mehal was greater than Patharnakh. The response of IBA levels was better than NAA levels. The survival of the Mehal cuttings was maximum (77.3%) when treated with 1000 ppm IBA, Whereas the maximum success (66.7% survival) in Patharnakh was observed when 500 ppm IBA was used. As such. 500 and 1000 ppm IBA may be used for clonal propagation of Patharnakh and Mehal rootstocks of pear respectively.
