释义

Definition of self-fertilization in English:

self-fertilization

(British self-fertilisation)
noun sɛlffəːtɪlʌɪˈzeɪʃ(ə)n
mass nounBiology
  • The fertilization of plants and some invertebrate animals by their own pollen or sperm rather than that of another individual.

    〔生〕(植物的)自花受精;(某些无脊椎动物的)自体受精

    Example sentencesExamples
    • Because self-incompatibility operates after pollination, it reduces geitonogamous self-fertilization but not geitonogamous pollination.
    • If so, is it autogamous (capable of self-fertilization in the absence of pollinators)?
    • Gametophytic self-incompatibility is a widespread mechanism in flowering plants that prevents self-fertilization and promotes out-crossing.
    • Together, the three modes of geitonogamy make a much larger contribution to self-fertilization than autogamy.
    • Consequently, the genetic structure of this species is likely to be shaped by rare outcrossing events among colonists, followed by generations of self-fertilization to produce recombinant inbred lineages.
