中文摘要：

对蓝猪耳花药发育中营养物质的分布和转化过程进行组织化学研究,结果表明：在造孢细胞时期,药壁细胞没有营养物质的积累,但在造孢细胞中有少量的脂滴;在小孢子母细胞时期,表皮细胞中出现淀粉粒,而在绒毡层细胞中出现脂滴,小孢子母细胞中也有脂滴的分布;在四分体时期,四分体小孢子中出现淀粉粒,绒毡层细胞脂滴增加;在小孢子早期,药室内壁细胞中出现淀粉粒,绒毡层继续积累脂滴,而小孢子中开始出现脂滴;到小孢子晚期,绒毡层细胞降解,细胞残留物中出现较多脂滴;在二胞花粉早期,花粉中的大液泡消失,花粉开始积累淀粉粒;在即将开花的成熟花粉中则积累了大量的脂滴和少量的淀粉粒。蓝猪耳花药发育中多糖和脂滴两种营养物质的积累和分布具有一定的时、空特点,反映出花药发育中营养物质积累的规律。

英文摘要：

The distribution of polysaccharides and lipid drops displayed some characters during the anther development of Torenia fournieri.At the sporogenous cell stage,neither starches nor lipids were in anther wall cells.Only a few lipids were in sporogenous cells.Before the meiosis of microspore mother cells,a few polysaccharides appeared in epidemic cells and a few lipid drops in tapetal cells which did not differentiate completely at this time.At the tetrad stage a few polysaccharides appeared in microspores and lipids in tapetal cells increased.After microspores were released from tetrads（early microspore stage）,starches appeared in endothecium cells and lipids in tapetal cells still increased.A few lipids appeared in microspores.At late microspore stage,tapetal cells began to degenerate,there were many lipids in degenerating tapetal cells.At early bicellular pollen stage,pollen began to accumulate lipids.With pollen development,many lipids were accumulated in vegetative cell of nearly mature pollen.
