The  results showed that wood .species  haB  significant effect  on penetration,  whi'le duration of  di/fusion storage period haB  the mme  effect  only on keruing, damar a8Clm,  balam and cengal banglai.Eight weeks of storage was better than 4  weeks on those timber,.  but not for the other species.
