Parmar University of Horticuture and Forestry, Nauni, Solan 173230 (H.P.) during 2011-2012. The study involved three experiments in all. Experiment-I, involved the determination of the effect of pre-sowing seed treatments on germination behavior of Myrica nagi, seeds were collected during second week of May, 2011 and depulped and subjected to various pre-sowing treatments. Application of concentrated H2SO4 for 10 minutes was found to be maximum germination percentage (33.33%), germination capacity (90.00%), germination energy (18.33%), germination speed (0.74) germination value (0.57) and germination index (0.28). The experiment-II, dealt with effect of auxins application on rooting behavior in pre-conditioned (girdled) stem cuttings of Myrica nagi . Twelve different treatments of growth hormones (Auxins) were used. Application of 1.0% IBA resulted in maximum Sprouting percent (70.00%), Callusing percent (66.66%), Rooting percent (23.33%), Survival percent (16.67) and Root Length (6.77cm) and proved to be most significant from all other treatments. The experiment-III, dealt with effect of auxins application on rooting behavior of Myrica nagi layered shoots in two seasons i.e. Summer (May) and Monsoon (July). Nine different treatments of growth hormones (Auxins) were used. Application of 0.5% NAA resulted in maximum Callusing percent (26.67%) , Rooting percent (36.67%), Survival percent (16.67%) and Root Length (12.33cm) in summer as compared to monsoon season i.e Callusing percent (16.67%), Rooting percent (33.33%), Survival percent (13.33%) and Root Length (10.83cm) respectively.enThesis
