- The generative cell and the vegetative nucleus are proposed to form a functional assemblage, the male germ unit (MGU). 生殖细胞一端伸入营养核裂片间隙，2者构成雄性生殖单位。
- The vegetative nucleus in a pollen grain moves into the pollen tube before the formation of two sperms and degenerates subsequently . [方法]应用常规石蜡切片和荧光显微技术，对水稻受精过程及其经历时间进行研究。
- There is no ~3H-tymidine incorporation into vegetative nucleus (Vn),generative nucleus (Gn) or nu- cleus of sperm in 96 hours before dehiscence of anthers (BDA). 散粉前96小时至精细胞形成,营养核、生殖核和精于核中均未见~3H-胸苷掺入。
- The results are as follows: Pollen grains germinate soon after pollination. 2 sperms enter pollen tube, leaving vegetative nucleus，which degenerates in pollen soon. 结果表明，授粉后，花粉随即萌发，2个精子进入花粉管，营养核留在花粉粒内，不久解体。
- After the pollen grain germinates on the surface of the stigma, the vegetative nucleus migrates to the tip of the pollen tube.It is thought to regulate the growth and development of the pollen tube. 花粉粒在柱头表面发育后，其内的营养核向花粉管顶部移动，因此认为营养核具有调节生长和花粉管发育的作用。
- Cupressus) the pollen grains contain just two nuclei: a GENERATIVE NUCLEUS and a VEGETATIVE NUCLEUS (tube nucleus). 当花粉粒形成后，花粉粒壁上分布有萌发孔，花粉管从萌发孔处向外突起形成管状结构，生殖核转入管中。
