| 摘 要： | 研究了三倍体毛白杨边材和心材在不同温度下纵向和横向渗透的速率。结果表明：纵向渗透速率远大于横向渗透速率;边材纵向渗透速率略大于心材纵向渗透速率;边材横向渗透速率与心材横向渗透速率几乎相同;温度越高,渗透速率越大。

| Abstract: | The penetration rates in axial direction and radical direction of sapwood and heartwood of triploid of polulus tomentosa in different temperatures were studied. The results show that the penetration rates in axial direction are more rapid than those in radical direction, the penetration rate in the axial direction of sapwood is a little more rapid than that in the axial direction of heartwood, the penetration rate in the radical direction of sapwood is almost the same as that in the radical direction of heartwood. The results also show that the higher the temperature is, the higher the penetration rate is. |
