摘要
通过对罗布麻营养器官解剖结构的研究,发现表皮细胞外都被有不同厚度的角质层膜;叶片气孔器都分布于叶的下表皮,且形成孔下室;根、茎、叶中含有大量的乳汁管;髓的外围形成一环内生韧皮部,这些结构特征使罗布麻能更好的适应干旱、盐碱等恶劣环境。
Many structural features were found to make Apocynum venetum better adapt to arid area and saline-alkali condition through the researches on vegetative organ anatomical structures of Apocynum venetum. Different thickness of cuticle was found on the outer of epidermal cells. Leaf stomatal apparatus forming substomatic chamber were all distributed on leaf lower epidermis. Plenty of laticiferous tubes were included in roots, stems and leaves. Intraxylary phloem formed around the pith.
