Precision management of pollination services to blueberry crops

open access: yesScientific Reports, 2021
While the cultivated area of pollinator-dependent crops is increasing, pollinator availability is decreasing, leading to problems in many agroecosystems.

Putting pollination quality into analyses of floral ecology: testing syndromes through pollinator performance [PDF]

open access: yes, 2012
Over recent years, the extent of specialised and generalised plant-pollinator relationships, and the predictive powers of floral traits (often grouped into “pollination syndromes”) as indicators of the most effective pollinators of plant species, have ...

MORPHOLOGICAL AND PHYSILOGICAL STUDIES ON FLOWERING, POLLINATION AND FRUITING OF “PICUAL” OLIVE TREES II- EFFECT OF SELF, OPEN, AND CROSS POLLINATION ON FRUIT SET, FRUIT DROP AND FRUIT CHARACTERISTICS [PDF]

open access: yesJournal of Plant Production, 2002
The influence of self, open and cross pollination (with two pollinizers, i.e. Kronaki and Coratina olive cvs.) on fruiting of Picual olive trees were studied during 1997 and 1998 seasons under Giza conditions.

The Economic Value of the Pollination Service, a Review Across Scales [PDF]

open access: yes, 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

Natural and artificial pollination of white-fleshed pitaya

open access: yesAnais da Academia Brasileira de Ciências, 2022
To produce pitaya (Hylocereus spp.), it is essential that pollination occur, either artificially or by pollinating agents. This study evaluated the viability of self-pollination, cross-pollination, and natural pollination, as well as pollen viability ...
