Self-pollination

Vanilla. Vanilla is the dried, cured, fuU-sized, but not fully ripe fmit pods (beans) of Vanillaplanifolia And. and V. tahitensis J. W. Moore (Orchidaceae). The vine is native to the tropical rain forests of southern Mexico, Central America, the West Indies, and northern South America. Plantings were started in Madagascar, Reunion, Java, Mauritius, and Zanzibar in 1840. The Madagascar-type bean is stUl the most important, but Indonesia produces more than Malagasy. The stmcture of the flower prevents self-pollination and therefore, where insects are not prevalent, hand pollination is necessary.

Camelina sativa, a rare and unexploited crop plant Camelina sativa is grown as a crop plant only in Finland and Ireland. Because it is a self-pollinating plant the risk of inadvertently transferring the new trait to naturally occurring plant relatives in the environment is low. Camelina sativa has not been extensively used in plant breeding, which means that there are only few varieties of the plant... 

Choice of host plant the plant is not widely cultivated in the area where the transgenic plants are grown, it has no wild relatives with which to cross and it is preferentially self-pollinating. 

Cereal expression systems are among the most advantageous for field-based recombinant protein production, since they combine intrinsic biosafety features (self-pollination in rice, barley and wheat, seed-specific protein expression) with practical ben-... 

Falseflax is a self-pollinating oilseed crop, rarely used for food, which originates from the Fertile Crescent This is also being developed as a sprout-based production platform by UniCrop Ltd, Helsinki, Finland (Chapter 3).

Hand pollinations in the greenhouse clearly showed the chief barrier to fertility in S. Divinorum is not a failure to be pollinated. Of a total of 108 self-pollinations (108 stigmas dusted with pollen from the same plant or genetically identical plants), only 11... 

In the following experiments the pollen, a rich source of auxin and gibberel-lins, was removed from the flowers so that the influence of different treatments on the ovaries could be studied. The flowers of Vitis vinifera are usually self-pollin-ated—i.e., the pollen usually falls on the stigma of the same flower. Emasculation experiments were performed as soon as five to ten calyptras had fallen from the... 

Plant breeding the purposeful manipulation of plant species in order to create desired genetic modifications for specific purposes. This manipulation usually involves either cross- or self-pollination, followed by artificial selection of progeny. 

Self-pollination pollen is delivered from the male stamen to the female stigma of the same plant. 

Inbred A self-pollinated plant that is genetically uniform. 

Pollination of Helianthus species is predominantly by honeybees and bumblebees (Cockerell, 1914), although other insects may be active. Helianthus are all-day flowers, presenting a continuous pollen and nectar resource for bees and other insects. Jerusalem artichoke, like nearly all Helianthus species, is largely self-incompatible, and as a consequence, cross-pollination is essential for the production of viable seed, with self-pollination being a rare event. 

In order to obtain hybrid seeds, self-pollination and pollination by a sibling plant must be avoided. It is sought to develop a female parental line accepting pollen from other lines (cross-pollination), without reproduction of its own line. This can be achieved directly through emasculation, i.e., elimination of the pollenbearing organ, usually at the expense of large labor requirements. Other methods can be used to induce male sterility. 

Modifications in the characteristics of sunflower are obtained through crosses to recombine genes from two sexually compatible parents. Both for self pollination and for controlled crosses, it is important that heads be isolated before flowering to avoid natural cross-pollination.
