Local evolution of obligate autogamy inEpipactis helleborine subsp.neerlandica (Orchidaceae)

Plant Systematics and Evolution, 2000
Isozyme analysis was used to assess the origin of the DanishEpipactis renzii, a local endemic of open coastal dunes. It seems to have evolved recently in several local populations of the more or less allogamousE. helleborine subsp.neerlandica. The obligately autogamousE. renzii is restricted to the easternmost part of the Danish range ofE.

Autogamy and Floral Longevity inMimulus guttatus

International Journal of Plant Sciences, 2002
Floral longevity is an important determinant of reproductive success in Mimulus guttatus. We conducted a series of experiments investigating floral longevity in the Iron Mountain population of M. guttatus under controlled conditions. In the absence of pollinators, flowers typically last 4–6 d.

Autogamy, allogamy, and pollination in some Canadian weeds

Canadian Journal of Botany, 1972
This paper is concerned with insect visitors to some Canadian weeds. It shows that both self-pollinating (autogamous) and cross-pollinating (allogamous) weeds are visited during the flowering period. It was found that self-incompatible species were visited by insects frequently, whereas self-compatible weeds were not visited or were rarely visited ...

Autogamy is induced in Paramecium bursaria by methyl cellulose

European Journal of Protistology, 2004
When isolated single cells of Paramecium bursaria were treated with 1.25% methyl cellulose, most of the single cells showed nuclear changes which were substantially similar to those seen in conjugation, suggesting that the cells undergo autogamy. Additional cytological observations indicated that the cells underwent normal nuclear processes during ...
