摘  要：
通过对两种试材东农42及其矮化突变体HK808,不同生长期外部形态建成及内部解剖学结构分析表明,两种试材的株高差异是由第5~13节间差异决定的。根部解剖学分析表明,东农42的导管面积显著大于HK808,导管面积与导管数量的动态曲线存在着互补的关系;HK808的根皮率显著高于东农42。两种试材茎部的导管面积及数量、薄壁细胞面积及数量均呈显著差异,维管束数目较稳定无差异。两种试材叶柄部各项解剖学指标比较分析结果与茎部相似;叶部东农42的叶片厚度及导管面积显著大于矮化突变体,HK808叶片的栅栏组织与海绵组织比显著大于东农42。两种试材电镜观察表明叶肉细胞叶绿体大小、叶绿体基粒片层数及片层形态均存在显著差异。

摘  要：
Dongnong 42 and its dwarf mutant-HK808 were used to analyze the external morphochoresis and its internal anatomical structure in different growing stage.The results indicated that the difference of height between the two test materials is determined by the different length of the internode 5-13.The anatomical structure analysis of root indicated that the Dongnong42 was much greater than HK808 in vascular area,there was a complementary relationship between the dynamic curve of the vascular area and the curve of vascular number in different varieties.Dongnong42 was significantly lower than HK808 in the bark/root ratio; there was significant difference in the area and number of vascular and parenchyma cells in stem between the two varieties,there is no significant difference in their vascular number.The anatomical indexes between the two varieties in petiole had the similar change pattern to that in stem.Leaf thickness and area of vascular of Dongnong42 was significantly higher than HK808 in leaf,palisade/spongy of HK808 is significantly higher than Dongnong42.There were significant differences between the two tested materials in the size of chloroplast,the number of chloroplast grana lamellar and the morphology of grana lamellar.
