ABSTRACT
The present investigation entitled “Propagation studies on Myrica nagi Thunb.” was
undertaken in the Department of Silviculture and Agroforestry, Dr. Y.S. 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.
