| 摘 要： | 利用超微技术对云南和河南烤烟叶片的细胞超微结构进行了比较研究。结果表明:在烟叶发育过程中,两地烟叶的超微结构变化规律基本一致,主要差异表现在淀粉粒与嗜锇颗粒上:在叶片发育早期,云南烟叶细胞中叶绿体及淀粉粒明显少于河南烟叶;在叶片发育中期,云南烟叶淀粉粒较多,嗜锇颗粒较少;在叶片发育后期,河南烟叶叶绿体降解迅速,嗜锇颗粒较多。

| Abstract: | The cellular ultrastructure of flue-cured tobacco leaves in Yunnan and Henan was compared by using ultramicro technique.The results revealed that: in the developmental process of tobacco leaves,the cellular ultrastructure displayed basically identical changing rule between the two ecological zones except for the starch grain and osmiophilic globule.When the leaf was at earlier developmental stage,the number of chloroplast and starch grain in the cell of tobacco leaves cultivated in Yunnan was less than that in Henan.At the middle developmental stage of leaves,the quantity of osmiophilic globule reduced,while the quantity of starch grain increased in Yunnan.At the latter developmental stage,the quantity of osmiophilic globule increased,while the chloroplast degraded fast in Henan. |
