permeability of twenty-two small diameter hardwoods growing on southern pine sites

Abstract

<:as pcrn~cability of hardwootls gro\ving on southern pine sites is significantly affectctl by ~noisture content in the longitudinal direction.The ratio of per~~rcability in the transverse to longitudinal directions is from 12,000:l for post oak to over 1,000,000:l for other oaks, but it is not affected by moisture.Although variation in longitudinal permeability varies grratly I~etween and among species, for most species there was no height effect.A significant diffcrrnce was detected between sapwood and corewood only in the longitudinal direction.Gas pc.rmeability tended to be solnewk~at less than liquid pc~rmeability.\drlitio~zal ke!/ruorclr: Gas pei~neabilit~,
