Pollination requirements of seeded and seedless mini watermelon varieties cultivated under protected environment

Pesquisa Agropecuária Brasileira, 2015
The objective of this work was to evaluate the floral biology and pollination requirements of seeded and seedless mini watermelon varieties, and to determine the best varieties to cultivate under protected environment.

Exploring Nectar Biology To Learn About Pollinators

The American Biology Teacher, 2000
Bees, moths, birds and other animal pollinators are responsible for producing approximately 80% of all the fruits that we eat daily (Buchmann 1997). Since pollinators are necessary for the reproductive success of many flowering plants, these plants need to attract and reward their pollinators.

Abundance of Pollinator Insect (Forcipomyia Spp .) of Cocoa Under Some Shade Trees [PDF]

, 2016
Cocoa production is affected by cocoa flowering and fruiting. The factor affects fruit seeting is pollinator agent such as Forcipomyia spp. Until now, information concerning population dynamics of Forcipomyia in some models of cocoa shading trees remains

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

American Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Floral biology and pollination in Brazil: history and possibilities

Acta Botânica Brasílica
Pollination research in Brazil virtually started with Fritz Muller, whose insights supported Darwin's evolutionary theory. Pollination systems of Brazilian plants were studied mainly by travelling researchers until early last century when native or ...

Duodichogamy and androdioecy in the Chinese Phyllanthaceae Bridelia tomentosa [PDF]

, 2007
Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that ...

The effect of drought stress on the limits and costs of plasticity in floral longevity in response to pollinator decline

American Journal of Botany, EarlyView.
Abstract Premise Declines in pollinator populations can reduce pollination services to plants, resulting in lower seed production. In response to these reductions, plants could increase the probability of pollinator visitation by plastically extending floral longevity.

Development of Artificial Intelligence for Quantitative Assessment of Nasal Inflammatory Cytology in Chronic Rhinitis by Whole‐Slide Images

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinitis (CR) is currently recognized as a syndrome that manifests in different phenotypes. We aimed to establish an artificial intelligence system (quantitative assessment of nasal inflammatory cytology, QANIC) on the basis of whole‐slide images (WSIs) to enable quantitative assessment of nasal inflammatory cells.

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...
