Abstract:

The photosynthetic cell structure of leaf sheaths at different positi-ons on the main stem in barley plants was observed.There are various types of photosynthetic cells in the leaf sheathsof barley plants.According to their shapes,these cells may be dividedinto two types:one is termed as regular cells,including simple cellsand complex cells with 2-5 linked protuberances;another is called ir-regular cells containing simple and complex cells with 2-6 irregularlylobed protuberances.The leaf sheath of barley sh...
