A growth analysis was made of first-order lateral shoots in three canopy layers of an evergreen Himalayan oak species (Quercus leucotrichophora or banj oak), growing under three banj oak forest stands at altitudes of 1160-1800 m above sea level. Determinate patterns of shoot growth differed by 7-15 days between lower and higher altitudes. Different levels of statistical significance were obtained for shoot length, diameter, and leaf numbers in extension growth during the first and second year of the study. At canopy level, the size of second-year shoots exceeded that of first-year shoots. The lower canopy layer differed significantly in shoot length from those of upper and middle layers, reflecting differences in resource-capturing ability. Leaf number per shoot was significantly higher in high altitude mixed-species forest than in oak-dominated stands. The author suggests that tree growth studies such as this analysis are useful not only in understanding the ecology of the species but also in conservation management.
