| 摘 要： | 以黑果花楸组培苗为试材,采用石蜡切片和叶表皮撕取法,比较正常苗与玻璃化苗茎叶横切面显微结构以及叶表面气孔特征。结果表明,黑果腺肋花楸栅栏组织由2~3层细胞构成,下表皮气孔下陷,小而密集,茎内分布大量导管、筛管。玻璃化苗主脉不明显,细胞排列凌乱不规则,栅栏组织与海绵组织的区别不明显,气孔开口大近圆形,茎肿胀粗大髓腔内薄壁细胞较多、已破裂。 |
| 关 键 词： | 黑果腺肋花楸 形态显微结构 正常苗 玻璃化苗 |

| Abstract: | The Aronia melanocarpa El oit was used as test material. The microstruc-ture of normal and vitrified shoots and the characteristics of their stomas on leaf surface were compared by paraffin section and leaf epidermis-tearing method. The results showed the palisade tissue of Aronia melanocarpa El oit consists of 2-3 lay-ers of cells. The stomas on lower epidermis cave in, and are smal and dense. There are abundant vessels and sieve tubes in stems. ln contrast, the main veins of vitrified shoots are unobvious, messy and irregular. The boundary between pal-isade tissue and spongy tissue is not obvious. The stomas open circularly and bigly. The stems are swel ing and thick, but the pith parenchyma cells are broken. |
