Study on the Micro-morphology of Leaf Lower Epdermis of the Tribe Triticeae from Shandong

摘要: 利用光学显微镜,对山东小麦族5属9种植物的叶片下表皮微形态特征进行了研究。叶片下表皮微形态在属间差异明显,可作为分属的参考依据;山东5种鹅观草属植物的叶片下表皮微形态可分为两种类型,这与形态上划分的拟披碱草组和犬草组相一致。

Abstract: The micro-morphology of leaf lower epidermis for 9 species(beloging to 5 genera) of the tribe Triticeae from Shandong were examined under light microscope(LM).It is considered that the micro-morphological characters of leaf lower epidermis could be used as evidence to distinguish genera because they are obviously different among the genera in this tribe.In addition,5 species of Roegneria may be divided into two types based on the micro-morphological characters of leaf lower epidermis,and it is in agreement with the classification into sect.Roegneria and sect.Cynopoa by its external characteristics.
