Century Dictionary and Cyclopedia
- n. In botany, a provision in hermaphrodite flowers to prevent self-fertilization by a difference in the time of maturity of the anthers and Stigma. It is distinguished as proterandrous or proterogynous, according as the anthers or the stigmas are the first to become mature.
- n. In zoology, the maturation in hermaphroditic animals of the ova and sperm at different times so as to preclude self-fertilization.
Wiktionary
GNU Webster's 1913
- n. (Bot.) The condition of certain species of plants, in which the stamens and pistil do not mature simultaneously, so that these plants can never fertilize themselves.
Examples
“Outcrossing is mainly achieved through dioecy and self-incompatibility, or promoted by dichogamy in the hermaphroditic flowers, and facilitated by wind pollination.”
“On the other hand all walnut, pecan, and hickory species are self-fertile and cross-fertile, but may be self-unfruitful because of dichogamy, because they may shed their pollen either before or after the stigmas of the pistillate flowers are receptive to it.”
“To overcome dichogamy it is necessary to have varieties which pollinate one another.”
“The simple methods belong to four principal classes: -- (1) By dichogamy -- that is, by the anthers and the stigma becoming mature or in a fit state for fertilisation at slightly different times on the same plant.”
“Two categories of dichogamy are protandry, the transition from male to female, and protogyny, the transition from female to male.”
“1942 NNGA Annual Report which clearly illustrates dichogamy in Persian walnut.”
“Even in 1863 we find Darwin explaining the meaning of dichogamy in a letter to Gray.)”
