Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Inbreeding depression in
Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

Fitness costs of delayed (self-) pollination in a mixed-mating plant [PDF]
Delayed selfing may provide reproductive assurance for plants facing unreliable pollination environments, but may negatively affect the reproductive performance due to inbreeding depression. Furthermore, floral senescence may impose an additional cost to

Amorphophallus titanum (Becc.) Becc. (Araceae) is native to the rainforests of Sumatra, and famously produces a single, massive, thermogenic, and highly odoriferous inflorescence. Despite having both male and female flowers in close proximity, A. titanum does not readily self‐pollinate as it is strictly dichogamous, with female flowers receptive on the

Effect of Climatic Conditions on Flowering of Walnut Genotypes in Romania [PDF]
The timing and lowering type of walnut genotypes (Juglans regia L.) is one of the important factors that lead to high and constant production. Therefore, the selection of homogame and spring frost tolerant genotypes has been among the most important ...

Do dichogamy and herkogamy reduce sexual interference in a self‐incompatible species? [PDF]
Summary 1. Dichogamy and herkogamy respectively represent the temporal and spatial separation of male and female reproductive functions. They are regarded as mechanisms to avoid selfing, to promote outcrossing and, particularly in self‐incompatible plants, to reduce sexual interference.

The evolution of dioecy from hermaphroditism allows for avoidance of self-pollination, and its evolutionary background has been investigated both experimentally and theoretically since it was first proposed by Darwin.

Stigmatic receptivity in a dichogamous early-divergent angiosperm species, Annona cherimola (Annonaceae): Influence of temperature and humidity [PDF]
9 Pag., 8 Fig.• Premise of the study: A variety of mechanisms to prevent inbreeding have arisen in different angiosperm taxa during plant evolution. In early-divergent angiosperms, a widespread system is dichogamy, in which female and male structures do ...
