| 1. | Cross - field pitting cupressoid with 1 - 5 pits 交叉场纹孔式柏木型。 |
| 2. | Bordered pits on tracheids radial walls uni - seriate and bi - seriate rows 交叉场1 - 4枚杉木型纹孔。 |
| 3. | Crossfield pit pair 交叉场纹孔对 |
| 4. | There are 2 taxa , taxodioxylon cryptomeripsoides schonfeld and taxodioxylon cunninghamioides in ltihe locality 射线导管间纹孔式互列,纹孔有明显的纹孔缘。 |
| 5. | Fiber - tracheid an elongated cell with bordered pits found in wood , intermediate in form between a fiber and a tracheid 纤维管胞:木材中具有具缘纹孔的细长细胞,是纤维和管胞的中间类型。 |
| 6. | Rays entirely parenchymatous , uni - serate ; horizontal and tangential walls of ray cells smooth and thin . cross - field pitting taxodoid with 1 - 4 pits 木射线单列,全由射线薄壁细胞组成;射线细胞水平壁薄,纹孔缺乏,端壁平滑。 |
| 7. | Sclerenchyma the main supporting tissue in plants , made up of cells with heavily thickened , often lignified , walls and empty lumina 厚壁组织:由细胞壁极度加厚,通常木质化的死细胞组成,是植物体内的一种主要支持组织,通常具有简单纹孔。 |
| 8. | Wood semi - ring - porous ; vessels solitary with angular outline ; perforation plates scalariform ; intervessel pits and vessel - ray pitting opposite or opposite to scalarifonn ; helical thickenings in vessel elements present 梯状穿孔板;管间纹孔式为互列;射线导管间纹孔式多对列,类似导管面间纹孔式。 |
| 9. | It was shown that vessel elements in secondary xylem of p . emblica have many different forms and most of them have tails and their perforation plates divide into two types : ( 1 ) there is one simple perforation plate at each end of the vessel elements and ( 2 ) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end ; ( 3 ) a few vessel elements have special inclusions ; ( 4 ) the intervascular pits are alternate pits ; ( 5 ) the pits between the vessels and rays are mixed pits , pits with transverse gashes and scalariform pits 结果发现,余甘子次生木质部导管分子中存在着许多不同的样式,导管分子大多数具尾;其穿孔板存在着两种类型: ( 1 )两端均为1个单穿孔板; ( 2 )一端为1个单穿孔板;另一端为2个单穿孔板; ( 3 )极少数的导管分子具有特殊的内含物; ( 4 )管间纹孔式为互列纹孔式; ( 5 )导管射线间纹孔式为混合型纹孔与横列刻痕状纹孔以及梯状穿孔。 |
