Radial Pattern of First-formed Early Wood Tracheid Length Variation from Pith to Bark in Deodar [Cedrus deodara (Roxb.) Loud].

Radial pattern of first-formed early wood tracheid length variation from pith to bark was studied with the main objectives of determining the effect of age, distance from pith, growth rate (distance/age) and ring width on first-formed early wood tracheid length among Deodar trees. There is rapid increase in tracheid length upto 10 years, afterwards the tracheid lengths either increases slowly or remains almost constant. It is positively and significantly correlated with independent variables like age, distance from pith and growth rate. The multiple correlation coefficients of these independent variables are also statistically significant.
