摘要:
<正>扫描电镜观察到毛果冷杉湿心材部位管胞具缘纹孔纹孔膜上存在着水痕状、片状或块状的细菌,而在正常材部位没有发现。细菌的活动不但使湿心材部位的部分射线薄壁细胞发生降解,而且纹孔膜塞缘的微纤丝束也偶尔被降解而产生断裂。生材时,湿心材管胞间的具缘纹孔纹孔膜严重结壳并闭塞,早、晚材管胞具缘纹孔的闭塞率分别为77.7%和72.1%,而正常材大多数是非闭塞的,早、晚材的闭塞程度分别只有6.8%和13.4%。湿心材中存在的大量闭塞纹孔,是导致木材干燥困难的主要原因。
Abstract:
The dynamics of stem sap flow of Abies fabric in Minjiang valley, which were the fundamental to research the hydrological recycle of this standing, were measured using ICT-2000TE based on thermal dissipation method in 2003. The results showed that the sap flow rate exhibited mono-peak patterns during day’s dynamics, and the maximum sap flow rate occurred at 12 or 13 o’clock. The main environmental factors to affect the sap flow rate of A. fabric included solar radiation, air temperature and air relative humidity. T.he correlation analysis indicated that there existed a close correlationship between solar radiation and sap flow rate.
