Description ABSTRACT
The present investigation entitled, “Propagation of three promising Himalayan fodder tree
species through stem cuttings” was conducted at the experimental nursery of the Department of
Silviculture and Agroforestry, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-
173230 (H. P.) during 2010- 2011. The study was carried out under three experiments, laid out in
Randomized Block Design (factorial) with three replications each. The study investigated the effect of
auxin-chemical formulation, preconditioning and cutting type on rooting behaviour of Morus serrata,
Pittosporum floribundum and Quercus glauca. The IBA concentrations ranged from 0.25 to 1.0% plus
each containing 2% captan + 2% sucrose. Cuttings were collected in two different periods of the year
(rainy and spring) from both girdled and non-girdled shoots and from two portions within the shoot
(apical and basal).
Treatment of cuttings with 0.25% IBA + 2% captan + 2% sucrose-talc in Morus serrata,
0.75% IBA + 2% captan + 2% sucrose-talc in Pittosporum floribundum and 0.5% IBA+2% captan+2%
sucrose-talc in Quercus glauca maximized rooting and root system of cuttings. In all the three species
girdled cuttings significantly outperformed the non-girdled ones. Cuttings of basal type showed
significantly better performance as compared to apical ones in Morus serrata and Quercus glauca,
while apical cuttings in rainy and basal cuttings in spring showed better success in Pittosporum
floribundum. Cuttings set in rainy season exhibited overall better performance in all the parameters in
Morus serrata and Pittosporum floribundum and vice versa in case of Quercus glauca. Significantly
highest rooting of 30 per cent with enhanced root characteristics was achieved when girdled Morus
serrata cuttings of basal type were treated with 0.25% IBA + 2% captan + 2% sucrose- talc and planted
during rainy season. In Pittosporum floribundum, significantly maximum rooting success of 63.33 per
cent with improved root system was recorded in girdled cuttings from apical portion treated with 0.75%
IBA + 2% captan + 2% sucrose-talc formulation and planted in rainy season. The maximum sprouting
(73.33%) and rooting (36.67%) success were achieved in Quercus glauca by planting in spring the
fresh cuttings of basal type treated with 0.25% IBA + 2% captan + 2% sucrose-talc and the girdled
basal cuttings treated with 0.5% IBA + 2% captan + 2% sucrose-talc respectively.
