ANDROMONOECY AND VARIATION IN PHENOTYPIC GENDER OF PASSIFLORA INCARNATA (PASSIFLORACEAE)

American Journal of Botany, 1988
We studied the perennial vine Passiflora incarnata Linnaeus (Passifloraceae) in Alachua County, Florida, from May to August 1983 to determine the breeding system and investigate seasonal changes in phenotypic gender of individual plants. Passiflora incarnata is an obligate outcrosser, incapable of self‐fertilization.

Andromonoecy in Four Australian Species of Leptospermum

Australian Journal of Botany, 1990
Leptospermum myrsinoides, L. juniperinum, L. laevigatum and L. lanigerum are recorded as being andromonoecious, with the proportion of total flowers that is functionally male averaging 36, 42, 48 and 14% respectively at Wilson's Promontory during the 1981-83 flowering seasons.

Development and mapping of a codominant SCAR marker linked to the andromonoecious gene of melon

Theoretical and Applied Genetics, 2005
Monoecy is an important goal for melon breeding because of the agronomic advantages it provides to parental lines in that they do not require hand emasculation to develop monoecious F1 hybrids, the latter producing fruits of higher quality. Monoecious phenotype is conferred by the dominant allele of the andromonoecious (a) gene, whereas recessive ...

EXPLAINING VARIATION IN POLLINATION AND SEED SET IN AN ANDROMONOECIOUS GENUS OF THE PROTEACEAE

Acta Horticulturae, 1997
Stirlingia comprises seven shrub species endemic to Western Australia, which are unusual in the Proteaceae in that they have inflorescences with male and hermaphrodite flowers. In Stirlingia virtually all hermaphrodite flowers produce a fruit. However fertile fruit set is very variable within and between the species.

Environmentally Influenced Changes in Sex Expression in an Andromonoecious Plant

Ecology, 1985
Sexual expression and maternal investment were investigated in the herbaceous perennial Solanum carolinense (Solanaceae). Field censuses, pollen germination studies, and the results of hand—pollination experiments in a greenhouse revealed that there are three flower types.

Regulation of Pollen Production in Anthriscus sylvestris, an Andromonoecious Species

International Journal of Plant Sciences, 1994
Pollen production per anther was investigated in relation to the gender and biomass of the flowers, their positions in the umbel, the number of flowers, the proportion of male flowers, and the sequence of flower development (order of umbel) in the common European andromonoecious species Anthriscus sylvestris. Male flowers have significantly less pollen

Floral biology and pollination in Cucumis melo L., a tropical andromonoecious cucurbit

Journal of Asia-Pacific Entomology, 2019
Abstract We studied floral biology and the role of flower visitors in fruit set of muskmelon (Cucumis melo L.). Muskmelon produced Staminate (hereafter ‘S’) and Hermaphrodite (hereafter ‘H’) flowers with a ratio of 18:1. Flowers opened around 40 days after planting and flowering continued for another 40 days.

ANDROMONOECY IN ZIGADENUS PANICULATUS (LILIACEAE): SPATIAL AND TEMPORAL PATTERNS OF SEX ALLOCATION

American Journal of Botany, 1993
I describe patterns of sex allocation and gamete packaging in the andromonoecious lily Zigadenus paniculatus. In this species, pistil length was continuously, but bimodally, distributed within plants, and smaller pistils contained fewer mature ovules.

Characterization of a new dominant Andromonoecy-causing locus in Cucumis Melo

Caractérisation d'un nouveau locus dominant causant l'Andromonoécie chez Cucumis Melo Chez les plantes, la détermination du sexe conduit au développement de fleurs unisexuées à partir d'un méristème floral bisexué. Ce mécanisme évolutif favorise la variabilité génétique.
