Cytological observation on the bulblet induction of Lilium oriental 'Sorbonne'.

The initiation and development of the bulbet of Lilium oriental 'Sorbonne' were studied by slicing up and histochemistry coloration.It was showed that the bulblet originated from 8-14th layer inner parenchyma cells near the axle of the scale.the development of bulblet could be diveded four stages according to morphogenesis changes.The saccharide was existed in meristematic tissue and vascular organization with mainly grain-like form,which was indicated that high content of saccharide could induce vascular organization,otherwise the protein was mainly distributed around nuclei duriong bulblet induction.The concentration gradient of saccharide and protein.was observed between meristematic tissue and surrounding parenchyma cells with higher saccharide and lower protein in the differentiation tissueand.
