摘要: 以兰州百合(L ilium davidii var. unicolor) 鳞茎中部鳞片为试材, 利用扫描电子显微技术, 研
究了鳞茎发育和低温贮藏过程中, 处于大维管束周围和大、小维管束中心位置的细胞内淀粉粒亚显微结构
变化。结果表明: 栽种期大维管束周围细胞中有少量淀粉粒游离在细胞腔内, 并有絮状物存在。随着鳞茎
的发育, 淀粉粒数量显著增加, 在植株半枯期达到最大, 形状由纺锤形逐渐变为近圆形; 处于大、小维管
束中心位置的细胞, 淀粉粒数量明显少于大维管束周围细胞中淀粉粒数量, 并且在营养生长期和花蕾透色
期, 淀粉粒表面有裂纹存在。低温贮藏过程中淀粉粒数量呈递减趋势, 在同一取样时期, 大、小维管束中
心位置细胞内淀粉粒数目明显高于大维管束周围的细胞, 与鳞茎发育过程中的情况相反。

Abstract: Changes in ultra-structure of starch granules in the middle scales of Lilium davidii var. unicol
or
bulb were studied with the scanning electron microscope ( SEM) during the bulb development and storage at
low temperature. The results indicated that a few separate starch granules coexisted with floccules in the cell
beside the big vascular bundle at planting stage. With the development of bulb, the amount of starch granules
increased significantly and reached the maximum at the half withered stage. Furthermore, the shape changes
were observed from sp indle to almost rotundity. For the cells between the big and small vascular bundle, the
amount of starch granules were smaller than that in the cells beside the big vascular bundle. And there are
some cracks on the surface of the starch granule at the vegetative growth stage and bud autumn stage. During
the storage at low temperature, the amount of starch granules tended to decline. By contrastwith the p rocess of
bulb development, the amount of starch granules in the cells between the big and small vascular bundle were
much more than that in the cells beside the big vascular bundle.
