| 摘要: |
| 用光镜和电镜对亲和性自体嫁接组合(番茄/番茄)和非亲和性异体嫁接组合(苋菜/番茄)进行了组织学细胞学比较观察。嫁接组合形成的早期阶段,两种组合隔离层两侧细胞中高尔基体、线粒体数量增多,细胞分裂形成愈份组织,表现出与愈伤反应一致的特征。后期,亲和性嫁接组合隔离层大部分消失,两侧细胞恢复正常状态,接穗砧木间有新分化的维管束桥相连,且有胞间连丝的次生形成,环状片层和壁旁体活跃地参与嫁接组合的形成过程;非亲和性嫁接组合中,隔离层不消失,附近出现死细胞层,接穗砧木之间无维管束桥相连。对观察的结果和有关问题作了讨论。 |

| Comparative Observation on Cytology during the Formation of a Compatible Autograft and an Incompatible Heterograft |

| Abstract: |
| With light microscope and transmission electron microscope the histological and cellular events that occurred near the graft interface are observed and studied during the formation of a compatible autograft(Lycopersicum esculentum)and an incompatible hetero- graft(Amaranthus tricolor/Lycopersicum esculentum).At the early stages of graft union de- velopment major events similarly occurred in both the compatible and incompatible graft. such as the increase of mitochondria and dictyosomes,appearaence of isolat... |
