polycarpy. Annual plants (therophytes) flower once then die, generally within a
few months of germination. Some longer lived plants also flower once, then die;
these are the monocarpic (semelparous) species. Most non-annual monocarpic ...
Certain varieties of the plum, for example, ordinarily produce a fairly large
proportion of double fruits. These result from the presence of two complete pistils
in a single blossom. Analogous cases of polycarpy occur in the apple, though
less ...
It is clear that the link has been repeatedly forged and broken during evolution,
as annual- ity/moncarpy/semelparity has given way to perenniality/polycarpy/
iteroparity within taxonomic groupings. In Charnov and Schaffer's (1973) view,
the ...
