Abstract:

A study was conducted on the Morphology and Anatomy of dwarf shoots of some exotic species of Pinus Linn. In Kumaon Hills, Western Himalayas” and hence morphological and anatomical details of the Pinus growing in above mentioned area.  These 5 species of Pinus were collected from different localities of Kumaon Himalayas including Nainital, Ranikhet, Almora, Kaushani and neighbouring areas in Western Himalayas, India. The five species of Pinus considered for the following study included P.canariensis C.Smith (three needles per fascicle), P. densiflora Siebold et Zuccarini (two needles per fascicle), P. engelmanii Carriere (three needles per fascicle), P. echinata Miller (three needles per fascicle) and P. gregii Engelmann (two needles per fascicle). The sections of the dwarf shoots of these species were taken from three different regions and their anatomical details such as shape of epidermal cells, number and position of resin ducts and ratio of cortex to wood were compared. These show interrelationships among different species using morphological, anatomical data. The anatomical details of the Pinus species and their correlation may be incorporated along with other diagnostic features needed for the identification and classification or systematic of these species. This work also attempts to provide a database for the systematics of different species which can be very useful for interspecific comparisons within the same territory and among different territories. The study revealed that anatomical variations in dwarf shoots can be taxonomically very helpful in identification of various species of Pinus
