Definition of self-sterile in English:

self-sterile

adjective sɛlfˈstɛrʌɪl

Biology

Incapable of self-fertilization.
〔生〕自花不稔的，自花不育的；自体不育的
Example sentencesExamples
- By contrast, mutant hermaphrodites are self-sterile when unmated due to a failure in spermatid activation.
- Outcrossed fruits from self-fertile plants contained significantly fewer seeds than did outcrossed fruits from self-sterile plants, but overall fitnesses of self-fertile and self-sterile plants were essentially equal.
- Second, there are no known cases in which all individuals of a population are self-sterile due to inbreeding depression, although complete self-sterility has been found in individual plants.
- Many plants, apparently physically equipped for self-fertilization, were completely self-sterile.
- Lower seed numbers in outcrossed fruits of self-fertile versus self-sterile plants probably reflect inbreeding depression due to mating of related individuals.

Derivatives

self-sterility

noun

Biology

Due to self-sterility, insect visitation is essential for full fruit set.
Example sentencesExamples
- Many pear cultivars exhibit self-sterility to one degree or another.
- This was accomplished by isolating single-conidium cultures from each progeny and testing for self-sterility and for mating type.
- This is because the genetic load required for complete self-sterility based on inbreeding depression is so unusually high that it is rarely, if ever, reached by any species.
- In fact, the evolutionary pathway from obligate outcrossing based on self-sterility to predominant self-fertilization is among the most common and widespread trends in flowering plants.
