描述了王百合（ＬｉｌｉｕｍｒｅｇａｌｅＷｉｌｓ．）及兰州百合（Ｌ．ｄａｖｉｄｉＤｕｃｈ．）质体和线粒体在生殖细胞及精细胞中的分布和细胞质中ＤＮＡ的状况。在刚形成的王百合的生殖细胞中含有少量的质体和大量的线粒体。当生殖细胞游离在营养细胞质中时，质体在生殖细胞中完全退化消失。ＤＡＰＩ荧光技术进一步证明，在成熟花粉、花粉管中的生殖细胞及其分裂形成的两个精细胞中无任何细胞器ＤＮＡ。兰州百合在小孢子分裂时质体严格地极性分布，造成了刚形成的生殖细胞中即无质体。兰州百合、麝香百合（Ｌ．ｌｏｎｇｉｆｌｏｒｕｍＴｈｕｎｂ．）及其杂种的ＲＦＬＰ分析，也证明兰州百合质体是单亲母系传递的。虽然在不同发育时期的生殖细胞及精细胞中可以观察到线粒体，但在雄配子体时期它们的ＤＮＡ已降解，因此雄性线粒体不能被传递至后代。研究结果提供了百合属的这两个种质体和线粒体具母系遗传方式的细胞学证据，并阐明父系细胞质不能作为遗传传递的机理。
The distribution of plastids and mitochondria in Lilium regaleWils. And L. davidiDuch. In germ cells and sperm cells and the DNA status in the cytoplasm are described. In the newly formed king lily reproductive cells contain a small amount of plastids and a large number of mitochondria. When the germ cells are free in the vegetative cytoplasm, the plastids completely disappear in the germ cells. DAPI fluorescence further proves that there is no organelle DNA in the mature pollen, the germ cells in the pollen tube, and the two sperm cells formed by their division. Lanzhou lily microspore division plastid strictly polarity distribution, resulting in the newly formed germ cells that no plastid. The RFLP analysis of L. longiflorum Thunb. And its hybrids also demonstrated that the P. platyphylla placenta was transmitted by single parent. Although mitochondria are observed in germ cells and sperm cells at different developmental stages, their DNA has degraded during the male gametophyte so that male mitochondria can not be transmitted to offspring. The results provide the cytological evidence of the maternal inheritance of these two germplasms and mitochondria in Lilium and elucidate that the parental cytoplasm can not act as a mechanism for genetic transmission.
