For instance, hand-pollination is used with date palms to avoid wasting space and energy growing sufficient male plants for adequate natural pollination. Because of the level of labor involved, hand-pollination is only an option on a small scale, used chiefly by small market gardeners and owners of individual plants.
Despite its logistical challenges, hand pollination was judged the most likely method to achieve fertilization and increase genetic exchange between nursery and wild individuals. Controlled propagation is used to reintroduce seedlings, since previous outplantings have an 80+% survivorship; [ 3 ] as the plants flower only once after many years.
The fruit is very sweet, reaching to 25 ºBx. It has desirable characteristics in the various aspects of production, [10] such as good productivity, with fruits of good conformation, when pollination is perfect. Good vigor of plants and relatively tolerant to the various fungal diseases that attack plants.
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.
Dates are naturally wind-pollinated, but in traditional oasis horticulture and modern commercial orchards, they are entirely hand-pollinated. Natural pollination occurs with about an equal number of male and female plants. With assistance, one male can pollinate up to 100 females.
The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old slave who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollinated. [3] Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean ...
