除了上述提到的“produce”、“reproduce”、“propagate”、“breed”和“multiply”等词汇外,还有一些与之密切相关的短语和词汇。例如,“sexual reproduction”表示有性繁殖,“asexual reproduction”表示无性繁殖,“fertilization”表示受精过程,“gestation”表示妊娠期,“parturition”表示分娩等...
As explained inHow Human Reproduction Works, higher organisms like plants, insects and animals reproducesexually, and this process makes the actions of evolution more interesting. Sexual reproduction can create a tremendous amount of variation within a species. For example, if two parents have multiple...
We still have no data on its size at sexual maturity or the relative contribution of sexual versus asexual reproduction to population dynamics. It remains possible that many dense stands of D. cylindrus are in fact made up of very few, or even single genotypes (e.g., [39]). Our ...
MAKING CLONES Cuttings are the basis of large indoor crops. Cannabis reproduces in two ways: sexually and asexually. Sexual reproduction occurs when the male fertilizes the female’s flowers with his pollen, which then produces seeds. Asexual reproduction occurs when a part of the plant emits ...
英文:In the context of plants, asexual reproduction often involves spores. 中文:在植物学中,无性生殖常常涉及孢子。 英文同义表达: “non-sexual”:这个表达强调的是不涉及性别的或非性行为的特性,如“non-sexual reproduction”(无性生殖)。 “genderless”:在社会性别语境下,这个词用...
Pathogenic fungal species hybrids infecting plants ÅkeOlson,JanStenlid, inMicrobes and Infection, 2002 The issue of hybridisation is not just a problem whenplant pathogenshybridise and new diseases are developed. Hybridisation is also an important issue for conservation biology. Increased hybridisation...
Sexual reproduction is almost ubiquitous among extant eukaryotes. As most asexual lineages are short-lived, abandoning sex is commonly regarded as an evolutionary dead end. Still, putative anciently asexual lineages challenge this view. One of the most s
Khasan (Kh), Blue Mountain (BM) and Sikhote-Alin (SA). Collected living plants were transferred to an open experimental nursery in the natural ginseng habitats (Spassky District of the Primorsky Kray) for further investigations; a part of the plants was also transferred to the laboratory greenh...
In seed plants, an understanding of the suite of life history changes accompanying the transition from outcrossing to selfing has recently been advanced by comparative analyses within lineages with both selfing and outcrossing species and by investigating the effects of key floral traits on variation ...
