以引种地库拉索芦荟为试材,通过田间试验和室内分析,综合应用解剖学、光学显微镜、荧光显微技术和石蜡切片技术相结合的方法,从形态学、细胞学、生殖生物学的角度进行研究。结果表明:芦荟花药壁的发育属基本型,完全分化时从外到内的细胞层依次是表皮、药室内壁、中层和绒毡层,其绒毡层属于腺质绒毡层。小孢子母细胞的减数分裂过程中胞质分裂为同时型,形成的小孢子四分体为左右对称型,成熟花粉为二细胞型。小孢子母细胞减数分裂过程出现异常,使小孢子呈现出不同程度的衰败,导致大量败育花粉产生,表现为雄性不育,导致库拉索芦荟雌性不育。
Aloe vera was used as tested material. Field experiments and laboratory analysis were conducted to study the effects of aloe vera on the development of aloe vera. Through the methods of combining anatomy, light microscope, fluorescence microscopy and paraffin sectioning, morphological, cytological and reproductive biology Angle study. The results showed that the development of aloe anther wall belongs to the basic type. When the cells were fully differentiated, the outer layer of epidermis, inner wall of the drug compartment, middle layer and tapetum, and the tapetum belonging to the glandular tapetum. During the process of meiosis of microspore mother cells, the cytokinesis was divided into two types, the cytoplasm was divided into two types, the microspore tetrad was symmetrical and the mature pollen was two-cell type. Microspore mother cell meiosis abnormalities, so that the microspores showed varying degrees of decline, resulting in a large number of abortion pollen, showing male sterility, resulting in female sterility Aloe vera.
