Adaptive growth strategy of Khasi pine (Pinus kesiya Royle ex Gordon)

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Three year old open grown pine saplings were selected. Three whorls of shoots were begun in one year. The species thus exhibits a recurrent flushing pattern. Two orders of shoots were recognised on the main leader during the study period of one year. Shoots produced at lower canopy levels attained less extension growth and fewer and shorter needles compared to shoots at higher canopy levels. The growth characteristics of shoots indicated shade intolerant nature of the species. The fascicles of 3 flushes appearing at different times of the year had different patterns of fall and life expectancy. The adaptive strategy of the growth pattern with recurrent flushing and short longevity of the needles are discussed and related to faster growth rate ofPinus kesiya in an early successional environment.
