The role of characteristic thickened cell walls contributing to the super-prolongation of flower ornamental periods

各种花叶具有美学价值，多年不枯萎或变色。本研究采用形态学和生物化学的方法对各种鳞状花叶片进行了表征。结果发现，所有细胞的次生细胞壁增厚，显示纤维素微原纤维的取向。植物次生细胞壁的精细结构不同。研究了木质花叶的中性碳水化合物组成。本研究提供了有关延长花观赏期细胞壁性状的知识。

The scarious floral leaves have aesthetic values without wilting or discoloration for many years. This research characterized scarious floral leaves by morphological and biochemical approach. In the result, we found the characteristic thickened secondary cell walls showing orientation of cellulose microfibrils for all cells. The fine structures of secondary cell walls varied in plant species. Neutral carbohydrate composition of scarious floral leaves were studied. This research provides knowledge about the cell wall characters involving the prolongation of flower ornamental periods.
