受精过程
2.(botany) development of an embryo without fertilization; (especially in some ferns) development of a sporophyte from the gametophyte without fertilization.
4.At fertilization, when the haploid gametes fuse, the diploid number of chromosomes is restored.
5.1. The process as the pollination and embryo sac development of early stable rice crossing cultivars were same as crosses between commons. Some single fertilizations were observed during pollination, but they did not influence the percentage of embryos (75.5%).
6.Fertilization by the union of gametes from different individuals, sometimes of different varieties or species.
7.Objective To investigate the behavior of cortical granules(CGs) during IVM and IVF, and the relationship between CGs and polyspermy.
8.male parthenogenesis in which the embryo contains only paternal chromosomes due to the failure of the egg nucleus to participate in fertilization.
9.STUDIES ON THE CULTIVATED INTERSPECIFIC HYBRIDIZATIONS BETWEEN PAIRS OF PINCTADA FUCATA,P.CHEMNITZI AND P.MAXIMA (MOLLUSCA,BIVALVIA) II .OBSERVATION ON THE CHROMOSOMES OF FERTILIZATION AND HYBRIDS
