摘 要 ：来自小枝梗的1条大维管束和3—6条小维管束进入小穗轴后分校出23—27条小维管束,它们其中2条通向护颖,5条通向外颖,3条通向内颖,4—8条通向浆片,3条通向子房和柱头,6条通向花丝。小穗轴中的小维管束大多被具有多孔的,相互间联络密切的厚壁细胞所包围。通向内外颖的维管束为有限外韧型维管束,木质部与初皮部分开。而通向浆片、

Abstract:One large and 3--6 small vascular bundles from the pedical got into the rachillaand subsequently branched into 23--27 small vascular bundles in a spikelet. Two ofthem went through to empty-glume, five to lemma, three to palea, four-eight tolodicule, three to ovary and stigma, six to filament. Most s
