  Abstract  
 

Myrica esculenta trees are distributed throughout Garhwal and Kumaon regions of Himalayas. In India it is locally known as kaphal; fruits are edible, sourish in taste. It is a non - legume nitrogen fixing tree species, enriches the soil nitrogen status and generally grown via seeds but due to hard seed coat results in unreliable germination pattern. Therefore, vegetative propagation an alternative technique (air layering) was tried to enhance survival and reduce the nursery cost and time. Air layering was tried for two consecutive years (2010-11 and 2011-12). Side by side seedlings were also grown through seeds and both vegetative as well as seedlings raised plants were grown in the field to compare the growth and survival performance. In air layering trial it was observed that maximum rooting was recorded in Indole Butyric Acid, 4000 ppm followed by 6000ppm; 2000ppm and minimum in 1000ppm however, no rooting was observed in control treatment. Rooting was only observed in the branches which were air layered either during post summer or rainy season whereas, no rooting during in winter or pre summer season. On field planting more than 73.68 percent in seedlings and 100 percent survival was recorded in vegetative grown plants after one year of growth.

Keywords: Air layering, growth and survival, hormonal doses, Myrica esculenta.
