| 摘要: |
| 利用组织化学方法对枫香树脂道发育过程的5个阶段的多糖物质、树脂的变化及其相互关系进行研究,结果为,随发育阶段的后移,基本组织细胞与树脂道上皮细胞内的多糖物质量与树脂量不断增加,在成熟阶段达到最大值;基本组织细胞形成多糖物质与树脂的时间均早于树脂道上皮细胞;树脂道上皮细胞所含多糖物质始终极少,而树脂总量变化明显,在树脂道发育成熟阶段,树脂充满整个细胞。提示树脂道上皮细胞并非是合成树脂的主要场所而是转运、贮存、分泌树脂的重要组织。 |

| Abstract: |
| The fluctuations of polysaccharides and resin in the five development phases of resin canal of Liquidambar formosana were studied by histochemistry.The results showed that the total of polysaccharides and resin in the parenchyma and secretory cells increased with the canal developing and went to the maximum in the mature time; the polysaccharides and resin originated in the canal cells later than in the parenchyma; the polysaccharides in secretory cells of resin canals kept in a little and its total was almost the same throughout lifecycle,but the total of resin changed markedly.It indicates that the secretory cells carries out the transport,store and secreting of resin, and wasn't a place of resin synthesis. |
