Using citizen science to monitor pollination services [PDF]

, 2015
1. Pollination by insects is a vital ecosystem service and the need for its assessment is increasing in recognition and political pressure, but there are currently no large-scale systematic monitoring schemes in place to measure the direct provision of ...

279 COMPARISON OF OPEN-POLLINATED AND HYBRID CALABAZA [PDF]

HortScience, 1994
Bush and short-vined calabazas [Cucurbita moschata (Duchesne) Poir.] derived from crosses of `Bush Butternut' with `La Primera' and `La Segunda' followed by several generations of selection and self pollination, are quite uniform in plant and fruit characteristics.

Comparative reproduction mechanisms of three species of Ocimum L. (Lamiaceae)

Acta Agrobotanica, 2016
Ocimum species have a combination of reproductive system which varies with the locality and cultivar. We have studied here the reproductive mechanisms of five variants of three Ocimum species in Nigeria, namely: Ocimum canum Sims., O. basilicum L., and O.

Open-pollinated Corn Variety Trial, 2001

, 2002
Based on requests from organic producers in Iowa for information on yields and grain quality of open-pollinated corn, a variety trial was developed at the Neely-Kinyon Farm in 2000 and 2001. Open-pollinated (O-P) corn often is preferred by organic farmers, and several O-P corn breeders are operating in Iowa and the Midwest to meet this demand.

Morphological Characterization and Classification of Open-pollinated Sweet Corn Cultivars [PDF]

Journal of the American Society for Horticultural Science, 1995
Sweet corn is one of the most important vegetable crops in the United States, however the morphology and phylogeny of open-pollinated sweet corn cultivars has not been studied. Fifty eight open-pollinated sweet corn cultivars were characterized with thirty-four descriptors to provide information for breeders interested in broadening the genetic base of

Variation of Cold Tolerance among Open-pollinated Sweet Corn Cultivars [PDF]

HortScience, 1997
Cold tolerance useful for sweet corn improvement may be present in open-pollinated (OP) cultivars. Cold tolerance in sweet corn is the ability to germinate, emerge, and grow under low temperatures. The cold tolerance of 35 open-pollinated sweet corn populations and controls was measured by growing the entries under 14 °C day/10 °C night in growth ...

Variability of the data indicating the fertility of different plum varieties

International Journal of Horticultural Science, 2003
Self-fertility and fertility at conditions of open pollination in plum varieties is strictly determined by genetic factors. However, rates of fruit set are highly variable according to growing sites as well as to seasons, which may result from a couple ...

Pollination services in the UK: how important are honeybees? [PDF]

, 2011
Pollination services are known to provide substantial benefits to human populations and agriculture in particular. Although many species are known to provide pollination services, honeybees (Apis mellifera) are often assumed to provide the majority of ...

Protecting an Ecosystem Service: Approaches to Understanding and Mitigating Threats to Wild Insect Pollinators [PDF]

, 2016
Insect pollination constitutes an ecosystem service of global importance, providing significant economic and aesthetic benefits as well as cultural value to human society, alongside vital ecological processes in terrestrial ecosystems.

The effect of blow flies (Diptera: Calliphoridae) on the size and weight of mangos (Mangifera indica L.) [PDF]

PeerJ, 2016
Background: Pollination has a great effect on the yield of fruit trees. Blow flies are considered as an effective pollinator compared to hand pollination in fruit orchards.
