电子显微镜观察结果表明，生长季山葡萄与玫瑰香叶片细胞亚显微结构无明显差异．随着秋季温度的降低，山葡萄叶绿体相互聚集，片层结构稳定，内部淀粉植减少见脂滴增加；液泡膜内陷，形成一些吞噬泡。落叶前，玫瑰香叶绿体中的淀粉粒亦减少，脂滴有增加的趋势，但片层结构清晰度明显下降，末见叶绿体聚集和吞噬泡的形成。 The results of electron microscopy showed that there was no significant difference in the sub-microstructure of the leaves between the grapevine and the rose. With the decrease of temperature in autumn, chloroplasts of grapevine cluster each other, the lamella structure was stable, the internal starch plant decreased and lipid droplets increased; the vacuole membrane invaded to form some phagocytic vacuoles. Before deciduous leaf, the starch grains in the rosewood chloroplast also decreased, the lipid droplet increased, but the clarity of the leaf layer decreased obviously, and finally the formation of chloroplast aggregation and phagocytosis was not seen.
