英文摘要	The distribution and characteristics of plastids and mitochondria in the generative and sperm cells of Lilium regale Wils. and L. davidii Duch. were described. In L. regale there were few plastids and abundant mitochondria in the newly formed generative cell. When the generative cell became free in the vegetative cytoplasm, the plastids degenerated completely within the generative cell. It was further proved by DAPI fluorescent technique that there was no organell DNA in the generative cell within the mature pollen grain or the pollen tube,However, distribution of the plastids was strictly polarizable during the division of the microspore in L. davidii, resulting the lack of plastids in the newly formed generative cell. Data of RFLP analysis comparable between L. davidii, L. longiflorum and their interspecific hybrid have also proved the plastid inheritance in L. davidii to be of uniparental maternal transmission. Although the mitochondria were observed both in the generative and sperm cells of L. regale and L. davidii but their DNA was decomposed in the male gametophyte stage. Therefore the mitochondria in the sperm cell could not be transmitted into the offspring. The results provided the detail, cytological, evidence that organelles in the microgametophyte are incapable of genetic transmission in the two species of Lilium.; Biochemistry & Molecular Biology; Plant Sciences; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 2; 2; 109-+; 40
