【摘要】 以霸贝杂交(Tillandsia Xero×Brachy)、霸王(Tillandsia Xerographica)、三色铁兰(Tillandsia tricolor)、赛肯达(Tillandsia Secunda)、维路提纳(Tillandsia Velutina)、索纳斯(Tillandsia Somnians)空气凤梨品种(种)为材料,用扫描电镜观察其叶表皮解剖学结构。结果表明,六种空气凤梨具有角质层发达,表皮毛密生,气孔凹陷等旱生植物典型的特征,品种间的表皮毛、栅栏组织、维管束等结构有很大的差异。以次推断这6种空气凤梨的抗旱能力依次是霸王>三色铁兰>霸贝杂交>赛肯达>维路提纳纳>索纳斯。更多还原

【Abstract】 Leaves epidermis of 6 species in genus Tillandsia were observed by standard electronic modules(SEM),he results showed that all the epidermises of the leaves were covered with heavy cuticle,thick trichomes and sunken stomata,which were the typical characteristics of xerophytes.However the trichomes,palisade tissue,spongy tissue and vascular bundle varied differently among the three species.The results showed that the drought resistance sequence from strong to weak was the sclerophyll (T.Xerographica,T.tricolor),the pliable(T.Xero×Brachy,T.Velutina),the vast(T.Secunda,T.Somnians).更多还原
