Cognitive Ecology of Pollination: Animal Behaviour and ...
In general, geitonogamy increases as a pollinator visits more flowers on a plant.
For example, consider the destinations of pollen removed from the first of five
flowers visited by a pollinator on a plant (Fig. 15.1a). Geitonogamous pollen
transfer ...

The fact that the bending movement occurs slowly was interpreted by Darwin (
1877) as a mechanism to prevent self-pollination among flowers on the same
plant (geitonogamy). In some cases bending movements are involved in
autogamy, ...

Ecology and Evolutionary Biology of Clonal Plants
Effects of clonal growth on mating patterns Individual size Recent studies on
pollination biology have drawn our attention to the ecological importance and
evolutionary consequences of geitonogamy, i.e., pollination between flowers of
the ...

Flowering Plants · Dicotyledons: Lamiales (Except ...
In terrestrial and amphibious species with aerial flowers, geitonogamy appears to
be more frequent than xenogamy (Philbrick and Anderson 1992; Jaggi and Cook
1998). Geitonogamy apparently takes place most readily when both staminate ...

Monocots: Systematics and Evolution: Systematics and Evolution
What evidence exists that geitonogamy is indeed higher in monomorphic versus
dimorphic enantiostyly and if so what is the function of monomorphic enantiostyly
? We addressed this problem by manipulating inflorescences of M. korsakovii ...

The Pollination Ecology of Hedysarum Boreale Nutt. ...
Therefore, fruit and seed production in H. boreale requires a floral visitor to move
pollen, at the very least, within or between flowers on a plant (geitonogamy).
Boyd and Serafini (1992) studied predehiscence and postdehiscence
reproductive ...

Diversity and Evolutionary Biology of Tropical Flowers
Two modes of inbreeding are possible: pollen transfer is within a single flower (
autogamy) or between different flowers on the same individual (geitonogamy).
Autogamy and geitonogamy may be different from a structural point of view, but
their ...
8
Evolution, Pollination Biology, and Biogeography of the ...
Though protandry may limit opportunities for pollen-stigma interference (Lloyd
and Webb 1986) and autogamy (i.e., same-flower selfing) that may cause
inbreeding depression (Charlesworth et al. 1987), it cannot ensure that
geitonogamy (i.e. ...

Pollination and Floral Ecology
Effects on Pollen Carryover and Pollen Discounting The extent of geitonogamy
within a plant will depend on patterns of pollen dispersal for each kind of visitor (
see fig 7.12). How much self-pollen and cross-pollen is deposited on a plant's ...

Black Pepper: Piper nigrum
Geitonogamy Geitonogamy is a self pollination mechanism which involves
gravitational descending of pollen grains combined with action of rain water or
dew drops. This is an effective mechanism in plants having long pendent
inflorescences ...
