1. There ware two cell proembryo and some endosperm free nucleuses in the embryo sac 7-8 days after pollination; 授粉后7-8天,在胚囊中见到二细胞原胚及数个胚乳游离核。
2. When electric currents (electrons) are passed through positively-charged gasses (protons and neutron nucleuses) inside bulbs. 当电子流通过灯泡中带正电荷的气体(质子和中子核)。
3. The experiment has proved that TMV-RNA multiplied vigorously in tobacco protoplasts with cellular nucleuses, while hardly multiplied in cytoplasts separated from nucleuses. 本试验证明了TMV - RNA在有细胞核的烟草原生质体中能大量增殖,但在无核的胞质体中却难以增殖。
4. The efferent projections of hypothalamic and brain stem nucleuses to nucleus dorsalis nervi vagi were studied by means of the retrograde axonal transport of HRP technique in cats. 本文用HRP轴突逆行输送法,对猫下丘脑和脑干一些核向迷走神经背核的传出投射进行了研究。
