DENDROCLIMATIC POTENTIAL OF PICEA SMITHIANA (WALL) BOISS. FROM AFGHANISTAN NASRULLAH KHAN, MOINUDDIN AHMED AND MOHAMMAD WAHAB Abstract: Modern Dendrochronological techniques were applied on Picea smithiana (Wall) Boiss, from District Dangam of Afghanistan. Twenty eight wood samples in the form of cores were obtained from 15 Picea trees and cross-dating was obtained among 24 cores of 12 trees. A first dated chronology (1663-2006AD) from this country was presented. Various statistics are described. It is indicated that all cores are highly correlated, showing similar climatic signals. On the basis of present investigations, it is suggested that this species has high Dendroclimatic value and more information could be obtained, if this chronology is correlated with other regional chronologies of the same species.
