High cross-pollination rate of Greek oregano (O. vulgare ssp. hirtum) with Common oregano (O. vulgare ssp. vulgare) under open field conditions as revealed by microsatellite marker analysis

Biotechnology & Biotechnological Equipment, 2023
We studied the mode of pollination in Greek oregano (Origanum vulgare ssp. hirtum) under both controlled and open pollination conditions. When grown indoors without the presence of insects, Greek oregano plants did not develop any seeds, indicating a low

Overview of Bee Pollination and Its Economic Value for Crop Production

Insects, 2021
Simple Summary There is a rising demand for food security in the face of threats posed by a growing human population. Bees as an insect play a crucial role in crop pollination alongside other animal pollinators such as bats, birds, beetles, moths ...

Effects of Pollination Method and Growing Location on Starch Thermal Properties of Corn Hybrids [PDF]

, 1998
Starch gelatinization and retrogradation properties of corn were studied to determine the effect of controlled (self) pollination versus noncontrolled pollination on analytical determinations, and the potential to eliminate the expensive and time ...

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 ...

Beyond the various contrivances by which orchids are pollinated: global patterns in orchid pollination biology

Botanical journal of the Linnean Society, 2023
Orchidaceae show remarkable diversity in pollination strategies, but how these strategies vary globally is not entirely clear. To identify regions and taxa that are data-rich and lend themselves to rigorous analyses or are data-poor and need attention,

Selfing Can Facilitate Transitions between Pollination Syndromes [PDF]

The American Naturalist, 2018
Pollinator-mediated selection on plants can favor transitions to a new pollinator depending on the relative abundances and efficiencies of pollinators present in the community. A frequently observed example is the transition from bee pollination to hummingbird pollination.

Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

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 ...
