Minute wood anatomy and key for the identification of important conifers of Pakistan
M. Ayaz and G. M. Nasir
ABSTRACT
Wood samples of Juniper, Spruce, Fir, Deodar, Yew and
four pine species were collected from different
coniferous forest of Pakistan. The objective was to study their microscopic structure for the preparation of
an identification key based on minute anatomy. Results
showed clear variations in the occurrence, number, size
and type of different anatomical structures, such as
resin canals, wood rays pits ray crossing, ray
tracheids, procumbent cells, vascular tracheids, pits on
vascular tracheids and pit pores. On the basis of these
anatomical variations a key is prepared for the
identification of important conifers of Pakistan.
