Pollination regulates a syndrome of developmental responses that contributes to successful sexual reproduction in higher plants. Pollination-regulated developmental events collectively prepare the flower for fertilization and embryogenesis while bringing about the loss of floral organs that have completed their function in pollen dispersal and reception. Components of this process include chang...

A breeding program has been developed since 1994 (done by Dr A. Trigui), by controlled pollinations of the Tunisian olive oil variety Chemlali Sfax in order to improve the qualities of this variety (higher oil percentage and a better chemical composition). These controlled pollinations have produced a population of new genotypes presented a wide genetic diversity which was very interesting for ...

Opuntia is the most diverse and widespread genus in Cactaceae; several species have broad distribution ranges successfully adapted to distinct habitats. One explanation for their success diversity of reproductive systems. macrocentra one common North American deserts. A previous work on a northern population documented that this has mixed-mating system receives low frequency pollinators. In sou...

From the biology’s point of view, pollination is an important step in the reproduction of seed plants. From our point of view, pollination is a promising and novel, biological paradigm for future dependable and self-managing computing systems. This estimation is based on the characteristics the pollination process between plants and insects im-

In this study the artificial pollination of pistachio was investigated. Two types of pollen of local selective genotypes (Q1 and Q2) which were different pollinizers were used. The experiment had six treatments. Qazvini and Ohadi cultivars were pollinated with supplementary pollinations as treatment which was covered with cotton bag, natural pollination as a control which was not covered and tw...

Animal-mediated pollination is essential for both ecosystem services and conservation of global biodiversity, but a growing body of work reveals that it is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects o...

Highbush blueberry yields are dependent on pollination by bees, and introduction of managed honey bees is the primary strategy used for pollination of this crop. Complementary pollination services are also provided by wild bees, yet highbush blueberry is increasingly grown in regions outside its native range where wild bee communities may be less adapted to the crop and growers may still be tes...
