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.
The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees ...
This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or ...
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.

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
Since the orchid is an endangered species, hand pollination may be used to propagate the species artificially. Research has shown that cross pollination and pollination with a single pollinium increase the number and viability of seeds produced. [7] Unlike for some other species, fire does not induce or increase the flowering of C. behrii. [3]
Hand pollination is the most reliable method in commercially grown vanilla. [9] Vanilla plantations require trees for the orchids to climb and anchor by its roots. [9] The fruit is termed "vanilla bean", though true beans are fabaceous eudicots not at all closely related to orchids.
