摘要

研究了玉米胚乳中自由核仁发育体育场的对跖间和对跖内变异。普通燕麦的对映体是单核或多核的。在单个细胞中,多核对跖体显示相同有丝分裂阶段的细胞核,但不同的对跖体是不同的。提供了有丝分裂期间发生的DNA扩增和异常的例子。

Antipodal symmetry and asymmetry in the embryo sac of Avena sativa L.
Inter- and intra-antipodal variation is presented for a free-nucleolar developmental stadium in the Avena sativa endosperm. Antipodals of common oat are uni- or multinuclear. Multinuclear antipodals, in a single cell, show nuclei of the same mitotic stage, but this is different for various antipodals. Examples of DNA amplification and anomalies occurring during mitosis are provided.
