冬枣大小孢子发生及雌雄配子体发育OA北大核心CSCDCSTPCD
Megasporogenesis, Microsporogenesis and Development of Female and Male Gametophytes of Ziziphus jujuba Mill.cv.Dongzao
为完善冬枣生殖生物学和枣树遗传改良理论基础,以不同发育时期的冬枣花蕾为材料,采用压片技术和常规石蜡切片技术,对冬枣大小孢子发生及雌雄配子体发育过程进行观察.结果表明,冬枣具五枚花药,花药四室,花药壁由表皮、药室内壁、1～2层中层和腺质型绒毡层组成,花药壁的发育属于基本型.小孢子母细胞胞质分裂为同时型,四分体的排列多数呈四面体型,成熟花粉具3个萌发孔,3沟,为二细胞型花粉.冬枣为2室子房,倒生胚珠,多胚珠,内外双层珠被,厚珠心;大孢子母细胞经减数分…查看全部>>
To improve the theoretical basis of reproductive biology and genetic improvement of jujube tree,megasporogenesis,microsporogenesis and development of female and male gametophyte of Zizipltus jujube Mill.cv.Dongzao were studied by means of squashing and routine paraffin section technique.The results showed that Dongzao consists of five anthers and each anther has four cavities.The wall of anther is composed of epidermis,endothecium,one or two middle layers an…查看全部>>
