摘要

禾科鹦鹉属(Aeluropus)在世界有5种，在伊朗有3种。这种盐生多年生植物分布在亚洲、欧洲和非洲的咸干土壤中。除了用作饲料外，它还可以通过根茎或匍匐茎稳定土壤。这些特点使欧耳草成为一种有价值的植物。本文利用扫描电子显微镜对10个居群的外稃和古稃进行了显微形态学研究，以确定所研究种间的诊断特征。研究了微刺、大毛、长细胞轮廓、软木和硅细胞、乳头、盐腺和表皮蜡等8个性状。在研究的种群/分类群中，盐腺和硅细胞的出现表明了栉水母对恶劣生境的耐受能力。研究结果表明小花微形态特征对分种具有一定的分类学价值。

Epidermal micromorphology of ﬂoret parts in Aeluropus (Poaceae)

Aeluropus from Poaceae comprises 5 species in the world and 3 species in Iran. This halophytic perennial is distributed in salty and dry soils of Asia, Europe, and Africa. In addition to being used as fodder, it can stabilize the soil by its rhizome or stolon. These features make Aeluropus a valuable plant. In this study, lemma and palea of 10 populations of Aeluropus were studied micromorphologically by scanning electron microscope (SEM) to determine diagnostic features among species studied. Eight characters as micro-prickle, macro-hair, long cell outline, cork and silica cells, papilla, salt gland, and epicuticular wax were studied. The occurrence of salt glands and silica cells in populations/taxa studied showed the ability of Aeluropus to tolerate harsh habitats. Our result showed the taxonomic value of ﬂoret micromorphological features to separate Aeluropus species.
