APOGAMY在英语中的意思是什么？

无融合生殖

Apomixis

在植物学中，无瘤假体由汉斯·温克勒（Hans Winkler）定义为无性繁殖的正常有性繁殖的替代，没有受精。 这个定义显然没有提到减数分裂。 因此，植物的“正常无性繁殖”（例如从切片或叶子的繁殖）从未被认为是无变性，而是通过小植物代替种子或用鳞茎替代花是无融合生殖的类型。 非生殖生产的后代在遗传上与母体植物相同。 一些作者包括所有形式的无性生殖的无性繁殖，但是该术语的泛化已经消失了。 在开花植物中，术语“无融合生殖”通常以有限的意义来使用来表示阿纳莫斯伯，即通过种子进行的克隆繁殖。 虽然理论上可以在裸子植物中发生agamospermy，但在该组中似乎不存在。 同义词是一个相关术语，随着时间的推移具有不同的含义。 在具有独立配子体的植物中，该术语仍然与“无融合生殖”互换使用，并且都指通过配子体细胞的孤雌生殖形成孢子体。

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization. This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils are types of apomixis. Apomictically produced offspring are genetically identical to the parent plant. Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e. clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes, the term is still used interchangeably with "apomixis", and both refer to the formation of sporophytes by parthenogenesis of gametophyte cells.

在英语 词典里apogamy的定义

字典中apogamy的定义是一种复制，发生在一些蕨类植物中，其中孢子体从配子体发育而来，而没有配子的融合。 apogamy的其他定义是开花植物的胚囊中的二倍体细胞发育成胚胎而不受精。
