Definition of fertilization in US English:

fertilization

(British fertilisation)

noun

Biology
  • 1The action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote.

    • ‘The embryos of all sexually reproducing organisms develop from a single cell, formed by the fusion of a male and a female gamete at fertilization.’
    • ‘In common with in vitro fertilisation, a gamete intrafallopian transfer cycle begins with superovulation to recruit multiple follicles and is followed by egg retrieval.’
    • ‘In cases where the female remates, we determine the relative fertilization success of each male.’
    • ‘A prepared sample containing around one to two million motile sperm is required for adequate oocyte fertilisation with in vitro fertilisation.’
    • ‘After several bouts of egg laying and fertilization, the female departs with fertilized eggs which she broods in her mouth.’
    • ‘It lures male codling moths on to a sticky platform (from which there is no escape) to limit fertilisation of the females and reduce the number of grubs, which feed inside developing fruits.’
    • ‘It likens it to now common reproductive technologies such as in vitro fertilization and artificial insemination.’
    • ‘It would not be reproductive cloning as fertilisation would involve only one set of gametes produced in this way and therefore a unique embryo would form.’
    • ‘In normal fertilisation the formation of male and female pronuclei is an important stage just before the maternal and paternal chromosomes start to pair up in preparation for the first cell division.’
    • ‘There was no evidence that increased familiarity with a site or with a female increased fertilization effectiveness for a male.’
    • ‘Instead, males that mate with mated females increase their fertilization success by being cannibalized.’
    • ‘There has been evolutionary growth in the technology of in vitro fertilisation and the gamete intrafallopian transfer programme.’
    • ‘The gametes then fuse in a process called syngamy, or fertilization.’
    • ‘If a female and male have sex within several days of the female's ovulation, fertilization can occur.’
    • ‘He said the above words in opposition to in vitro fertilisation, not stem cell research.’
    • ‘Once these discoveries had been made, it was no longer possible to deny that animal life begins at fertilisation.’
    • ‘Wrasses practice external fertilization in which the female's eggs are released into the water.’
    • ‘The act also requires that no person should provide gametes for in vitro fertilisation, storage, or donation without first being given appropriate information about treatment.’
    • ‘Some genes have been shown to be expressed in the female gametophyte before fertilization.’
    • ‘During these two to three weeks after fertilization, the male will protect the nest and guard the eggs with great fierceness.’

    1. 1.1 The action or process of applying a fertilizer to soil or land.
      • ‘Reduce nitrogen fertilization, and test soil to check potassium levels.’
      • ‘Bermudagrass is highly responsive to fertilization with N and can be an important and valuable cash crop.’
      • ‘Forage fertilization should be based on soil test levels and realistic yield goals.’
      • ‘Adequate fertilization is an economical practice for increasing pasture production.’
      • ‘Forages are generally good sources of calcium and can be variable in phosphorus according to soil type and fertilization.’
      • ‘Susceptibility to cold is determined by cultivar and cultural practices, especially fertilization.’
      • ‘Deciding to perform fall fertilization, or deciding not to, presents risks and benefits that must be considered.’
      • ‘Shallow soil or inadequate fertilization also can cause nuts to drop.’
      • ‘Frequently, the health and vigor of trees stressed by construction activities can be improved by fertilization.’
      • ‘They all prefer acidic soil and require regular fertilization through the growing season.’
      • ‘Sánchez trained tens of thousands of farmers and extension agents in soil conservation and organic fertilization.’
      • ‘They are widely distributed from rainforests to the edges of dry and cold deserts, and they play an important role in human nutrition as well as in soil fertilization.’
      • ‘The cultural practices and fertilization practices recommended for wheat are satisfactory for triticale.’
      • ‘Modern culturing of wheat involves large land areas with intensive fertilization to achieve large yields and high protein concentrations.’
      • ‘The variety grown here is well adapted to the climate, requiring less water and fertilization than modern hybrids.’
      • ‘The objective was to demonstrate proper fertilization and harvesting practices to improve hay quality.’
      • ‘Improperly done fertilization may actually increase undesirable weed growth and contribute to other problems.’
      • ‘We've made huge advances in agricultural mechanization, in fertilization, in soil science.’
      • ‘No additional fertilization was applied to that already present in the growing medium during the experiment.’
      • ‘The effect of rootstock on wine quality is probably no greater than that of other factors such as soil, climate, fertilization, and irrigation.’
