摘要
对盐肤木茎进行木材解剖学研究,发现其导管分子穿孔板为单穿孔板。根据穿孔板在导管分子上的位置和数量,导管分子可分为4种类型,即只有一个单穿孔板,位于导管中央,且具有螺纹增厚;两端均为单穿孔板,且具螺纹增厚;两端均为单穿孔板,且具有孔纹增厚;具三个单穿孔板,一端有2个,另一端有1个,且具螺纹增厚。组成细胞中还有分隔木纤维、螺纹管胞。盐肤木为环孔材,射线为异形射线。
The study of the stem’s secondary xylem of Rhus chinensis Mill reveals that perforation plate is simple perforation plate. There are 4 types vassel elements with different location and number of simple perforation on vassel element wall: these is only one simple perforation plate in the middle of the vassel element, and with helical thickening; each end of the vassel element has a simple perforation plate, and with helical thickening; each end of the vassel element has a simple perforation plate, and with reticular thickening; there are 3 simple perforation plates, and one end has two simple perforation plates, and the other end has one simple perforation plate. There are also helical tracheids and septate fibres in the secondary xylem. It is ring porous wood. The ray is heter geneous ray.
