摘要:
用石蜡切片、半薄切片和超薄切片方法研究了麻疯树种子发育过程中脂类物质的变化。结果表明:脂类物质主要储存于胚乳当中,当种子发育成熟时胚乳中迅速积累了大量的油脂;种皮在发育过程中脂类物质含量较多,成熟时外种皮硬化,内种皮含有大量的油脂;种子成熟时胚中含有少量的脂类物质。细胞内脂类物质含量比较多时,内质网、线粒体、质体和高尔基体数量也会较多。种子完全成熟时进行采收加工是最为合适的。
Abstract:
The micro-structure and ultra-structure of the lipids during the seed development in Jatropha curcas were studied by paraffin sectioning,semithin sectioning and ultrathin sectioning. The results showed that the lipids were mainly stored in endosperm. The endosperm was rich in lipids at maturity. Seed coats were abundant in lipids during seed development. The outer coat was sclerified and the inner coat was rich in lipids at maturity. The embryo had a few lipids at maturity. Organells including endoplasmic reticulum,mitochondria,plastids and dictyosome were abundant in the cell when lipids were rich. It was the most appropriate time to harvest and process when the seeds were fully matured.
