BACKGROUND AND AIMS Cucumis melo subsp. agrestis (Cucurbitaceae) is cultivated in many African regions for its edible kernels used as a soup thickener. The plant, an annual, andromonoecious, trailing-vine species, is of high social, cultural and economic value for local communities. In order to improve the yield of this crop, the first step and our aim were to elucidate its breeding system. M...

In red clover seed production, low yield is limiting the commercial exploitation of tetraploid clover. To explore if pollination factor for in clover, we investigated pollinator behaviour and plant reproductive success diploid (2x) cultivar ‘Rajah' (4x) ‘Amos' using honey bee hand approaches. We measured set at flower head level with increasing visitation rate bees (one bee, two open pollinatio...

It is accepted that the papilionaceous corolla of the Fabaceae evolved under the selective pressure of bee pollinators. Morphology and function of different parts of Coronilla emerus L. flowers were related to their role in the pollination mechanism. The corolla has a vexillum with red nectar lines, a keel hiding stamens and pistil, and two wing petals fasten to the keel with two notched folds....

We investigated the reproductive biology of three plants endemic to rosemary scrub habitats on the Lake Wales Ridge of Florida, USA. We used hand-pollination experiments and observations of flowers and their insect visitors to determine their mating systems and pollination. Fruit or seed set after self pollination was 94, 97, and 8% of fruit or seed set after cross pollination in Eryngium cunei...

Floral traits have largely been attributed to phenotypic selection in plant-pollinator interactions. However, the strength of this link has rarely been ascertained with real pollinators. We conducted pollinator observations and estimated selection through female fitness on flowering phenology and floral traits between two Primula secundiflora populations. We quantified pollinator-mediated selec...

Pollination is critical for the production of many crops, and both insect- wind-based pollination systems are increasingly disrupted by bloom asynchrony, weather events, high demand available insect pollinators. Artificial can provide a security yield even in poor scenarios, have been attracting increasing attention over past decade. Here, we review pollen collection application technologies th...

This study presents breeding and pollination systems of Aristolochia maxima and A. inflata in a seasonal tropical forest of Panama. Aristolochia is the most diverse genus of Aristolochiaceae, with ∼120 species distributed throughout the tropics and subtropics. All the Aristolochia species studied so far are pollinated by saprophagous flies of different families, which are presumably deceived by...

Flower stalks of Pulsatilla cernua, an early spring herb in north temperate Asia, changed position from erect to pendulous and back to erect during 6-10 d anthesis. We tested three possible explanations for this movement. Our results showed that (1) this movement is unlikely to be a mechanism to attract pollinators or enhance pollen output, because no pollinator preference was observed between ...

Passion fruit plants are self-incompatible and fruiting is exclusively dependent on cross-pollination, which in nature performed by carpenter (mamangava) bees, especially Xylocopa spp. (family Apidae). To ensure satisfactory productivity, daily manual pollination a common practice among passionflower growers. Therefore, we studied whether mechanically transmits the cowpea aphid-borne mosaic vir...

Abstract Producing seeds from shallot flower requires proper pollination techniques to form pithy seeds. This study aims determine the effectiveness of several methods in producing true (TSS). The research was conducted Cilame Village, Ngamprah District, West Bandung Regency, Java at an altitude 900 m asl. used a completely randomized design (CRD) which consisted four treatments and six replica...
