Abstract

ABSTRACT Investigations were carried out at research garden of the Pakistan Council of Scientific and Industrial Research, Laboratories, Peshawar, during 1974, to find out the best root promoting hormones for root initiation and economic propagation of olive, Olea europea L. cultivar Leceino cuttings. Three growth regulators namely, Indole 3-acetic acid, Indole 3-butyric acid and 1-Naphthalene acetic acid each with 3000, 6000 and 9000 PPM in 50%alcohol were used as Quick Dip method on the semi hardwood cuttings of the aforesaid species. Better routings (22.25%) were produced with Indole 3-butyric acid at 6000PPM as compared to I.A.A. and NAA. The non-treated cuttings totally failed to produce any roots. The number and length of roots per cutting were greater with 9000 PPM of Indole butyric acid. In general the effect of 1-Naphthalene acetic acid was found comparatively inferior Indole 3-acetic acid and Indole 3-butyric acid.
