Abstract

The current study was conducted to test the effect of auxins application on rooting behavior of Myricanagi Thunb. at Bagaur and Mazgaon farm nursery of the Department of Silviculture and Agroforestry, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Himachal Pradesh (India.) during 2011-2012. Twelve different treatments of growth hormones (Auxins) were used to test the effect of auxins application on rooting behavior in pre-conditioned stem cuttings. 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. Effect of auxins application on rooting behavior of Myricanagi layered shoots was tested in two seasons, i.e. Summer (May) and Monsoon (July) by applying nine different treatments. 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.
