The effect of wick action on the moisture distribution in heartwood and sapwood stakes of Pinus radiata D. Don.

IRG/WP 99-40139

J Hann, P Vinden

The pattern of moisture distribution in stakes of Pinus radiata D. Don. subjected to "wick action" is investigated. There was incomplete saturation of the stakes even after 93 days of continual soaking. Maximum moisture absorption occurred at the base of the stake and at the air/water interface of the stake. Incomplete saturation of the stake was thought to be due to air embolism within the wood. The higher moisture contents observed at the air/water interface were thought to be due to moisture evaporation from the top of the stakes, overcoming the influence of air embolism.
