Evidence of widespread pollen limitation in diverse specialty crops on commercial farms
Royal Society Open ScienceSpecialty crops (non-staple fruits and vegetables) have diverse pollination requirements and pollinator communities, yet production may be limited by pollen limitation.

Journal of Visualized Experiments, 2020 Self-incompatibility in Rosaceae is determined by a Gametophytic Self-Incompatibility System (GSI) that is mainly controlled by the multiallelic locus S. In apricot, the determination of self- and inter-(in)compatibility relationships is increasingly important, since the release of an important number of new cultivars has resulted in the increase of ...

Türkiye Tarımsal Araştırmalar Dergisi, 2015 Pollination is a prerequisite system for reproductive of many plants and it is more important in self-compatible plants. Since, these plants need other flowers pollen for flower fertilization and seed production.

The Economic Value of the Pollination Service, a Review Across Scales
, 2009 Pollination is an ecosystem service that is essential to support the production of a wide range of crops. The service is increasingly under threat, as a consequence of among others habitat loss of pollinators and increasing use of pesticides. In order to

Development of a Labor-Efficient Hand Pollination Procedure for Flowering Dogwood [PDF]
Journal of Environmental Horticulture, 1999 Abstract The effect of frequency and timing of hand pollinations on seed set in flowering dogwood (Cornus florida L.) was studied. Six hand pollination treatments and an open-pollinated control were included in this study. The hand pollination treatments, which utilized non-emasculated flowers, were performed over a 12-day period beginning with

Role of insects in the pollination of Acacia nigrescens (Fabaceae)
, 2006 We examined pollination biology of Acacia nigrescens Oliver, flowering at the end of the dry season in Kruger National Park, South Africa. A. nigrescens produces small quantities of concentrated nectar, and has abundant pollen resources available to ...

Journal of Agricultural and Marine Sciences, 2002 Date palms were pollinated by hand, hand duster and motorized duster. Pollen for the hand and motorized dusters was diluted with wheat flour each at 1:5, 1:7, 1:9 and 1:14 ratios. Fruit samples were collected during ‘Hababook’, ‘Kimri’, ‘Bisir’, ‘Rutab’,

Big bees do a better job : intraspecific size variation influences pollination effectiveness
, 2014 Funding: School of Biology, University of St AndrewsBumblebees (Bombus spp.) are efficient pollinators of many flowering plants, yet the pollen deposition performance of individual bees has not been investigated.

Typology in pollination biology: lessons from an historical critique
, 2011 Typological schemes that describe putative floral adaptations for pollinators have played a central role in pollination biology. In 1882 the prominent German botanist and Darwinist Hermann Müller commented critically on a precursor of modern versions of ...

Role of Wound Ethylene in Fruit Set of Hand-pollinated Muskmelons1
Journal of the American Society for Horticultural Science, 1978 Abstract Application of a lanolin paste containing the aminoethoxy analog of rhizobitoxine, aminoethoxyvinylglycine (AVG), to the base of perfect flowers improved fruit set in emasculated, hand-pollinated flowers of muskmelon ( Cucumis melo L.).
