This paper reports on the shoot diameter and shoot elongation of common 10 trees and 9 shrubs species of 6 natural forests occurring between 350 to 2500 m in Kumaun Himalaya. The findings indicated that over 90% shoot elongation was accomplished prior to the commencement of rainy season in a majority of species. The average values of diameter increment were similar for canopy and subcanopy species and it was markedly higher for open grown deciduous species. In shrubs, it was higher for deciduous species. The relationship between the shoot length and shoot diameter in all species was positive and significant.
Key words: Kumaun Himalaya, shoot length, shoot diameter.
