摘　　要：应用组织切片,扫描电镜和透射电镜技术研究了山西农业大学人工合成的异源四倍体亚比棉蜜腺的分布、形态和结构。结果显示蜜腺在叶、花上均有分布,且蜜腺结构基本相似,均由分泌细胞、柄细胞、基细胞和亚腺组织构成;蜜腺组织中各类细胞器均很丰富,共同特点是富有线粒体、核糖体、内质网和大而清晰的细胞核及核仁,说明蜜腺组织在代谢上十分活跃。The distribution, morphology and structure of nectary of a new cotton species named allotetraploid Gossypium arboreum bickii which was bred artificially in Shanxi Agricultural University are studied by using the technology of tissue section through Light Scanning Electron Microscope (SEM ) and Transmission Electron Microscope (TEM). Results show that nectaries are distributed in both leaves and flowers, moreover, the structure of all nectaries are similar which are generally composed of secretory cell, stalk cell, foot cell, and subgland; the organelles appear abundant in the cell of nectary tissue, such as mitochondrions, ribosomes and endoplasmic reticula, and big and clear nucleus and nucleolus, showing that there are many active and vigorous metabolism in nectary tissue.
