  Fruit tree pollination - Wikipedia, the free encyclopedia
Symptoms of inadequate pollination are small and mishapen apples, and slowness to ripen.
Citrus that requires pollination may be self compatible, thus pollen must be moved only a short distance from the anther to the stigma by a pollinator.
Hand pollination by a human pollinator is a solution, though it is important to learn whether the variety is self fertile or self incompatible.

 Pollination
Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (male gametes) to the plant carpel, the structure that contains the ovule (female gamete).
The process of pollination requires pollinators as agents that carry or move the pollen grains from the anther to the receptive part of the carpel.
Pollination management is a branch of horticulture that seeks to protect and enhance present pollinators and often involves the culture and addition of pollinators in monoculture situations, such as commercial fruit orchards.

Pollination is the transfer of pollen grains (male gametes) to the plant carpel, the flower structure that contains the ovule (female gamete).
The process of pollination requires pollinators as agents that carry or move the pollen grains from the anther to the receptive part of a female flower or flower part.
(Pollinator and pollenizer are often confused: a pollinator is the agent that moves the pollen, whether it be wind, bees, bats, moths, or birds; a pollenizer is the plant that provides the pollen.) Some plants are self fertile or self compatible, and can pollenize themselves.

 Fruit tree - Wikipedia, the free encyclopedia
A fruit tree is a tree bearing fruit — the structures formed by the ripened ovary of a flower containing one or more seeds.
However, because all trees of flowering plants produce fruit (essentially all trees except tree ferns and gymnosperms), the term in horticultural usage applies to trees providing fruit as human food.
Types of fruits are described and defined elsewhere (see Fruit), but would include fruit in a culinary sense as well as some nut bearing trees, like walnuts.

 Fruit
Botanically, a fruit is the ripened ovary of a flowering plant, dry or moist and fleshy.
Some culinary fruits are not fruits in the botanical sense, for example rhubarb: only the stems are edible.
Some fruits have coats covered with spikes or hooked burrs, to prevent themselves from being eaten by animals and/or to stick to the hairs of animals, using them as dispersal agents.

 Pollination Requirements for Tree and Small Fruits
In the flower, pollination is the transfer of pollen from the anther to the stigma.
Pollination is an important factor when selecting and planting tree and small fruits.
Fruit trees which require two different varieties for pollination should be planted within 50 to 100 feet of one another to insure good fruit set.

 Fruit tree pollination
The normal failure in the setting of fruit blossoms may be due to a number of causes; as poorly nourished fruit-buds, lack of pollination, or winter injury to the pistils which cannot be seen with the eye alone.
The injury to fruit blossoms from cold is of all degrees.
The poor setting of fruit which often follows a long rain and sometimes a shower is due more to a loss of vitality in the pollen or to some mechanical injury to the pistils; also, in large measure, to the fact that bees and other insects which promote the beneficial cross­pollination between varieties are absent.

 Why Fruit Trees Fail to Bloom
Trees growing at a moderate rate generally bear fruit sooner than those grown either too quickly or too slowly.
Some species of fruit trees have perfect flowers, where both the anthers, which contain pollen, and the pistils, which develop into fruit, are located in the same blossom.
Trees that bear fruit as a result of pollination from their own anthers are considered self-fruitful.

 FRUIT
The mature size of a fruit tree is determined by rootstocks and sometimes by an INTERSTEM graft.
Fruit trees are deep rooted, so good drainage of the subsoil is critical to proper root development.
After planting, all fruit trees should be pruned to a height of 24 to 28 inches.

 Fruit Tree Care
All of our fruit trees are grown on a semi-dwarfing root stock so that they are just the right size for your yard.
Fruit trees are generally quite tolerant to a wide variety of soil conditions.
A general purpose fruit tree (fungicide and insecticide) spray should be used starting with the 1st signs of emerging leaves in the spring.

 Fruit Tree - Landscape Tree - Landscaping Tree - Shade Tree
When selecting the right fruit tree for your yard, there are several factors to look at other than the obvious one of what fruit you’d like to eat.
Most fruit trees are also available as dwarfs so if you have limited space or want to grow them in a container this may be an option.
These trees are deciduous (meaning they drop their leaves in the fall) and many put on a spectacular display of red, pink or white blossoms in the spring.

 California Backyard Orchard - Pollination   (Site not responding. Last check: 2007-10-15)
Pollination is the transfer of pollen to the stigma from stamens of the same or a different flower.
Trees that bear fruit from self-pollination or from pollen from another plant of the same kind, or set fruit without pollination are called self-fruitful or self-pollinating or self-fertile.
However, there are many types of fruit trees with perfect flowers that cannot produce fruit from their own pollen.

 Why Fruit Trees Won't Bear   (Site not responding. Last check: 2007-10-15)
Tree health and environment, bearing habit, and the cultural practices used can all directly influence its ability to produce fruit.
Cross-pollination is required for most tree fruits; therefore, it is essential to plant two or three different varieties to insure fruitfulness.
Fruit trees that are grown near large shade trees are often poor producers.

Bare-root trees are just as easy to grow as container grown trees when planted correctly and at the right time of year.
Some trees, particularly peach, plum, pear, and apple trees require a certain number of chill hours to break bud in the spring and produce fruit.
Some trees are self-fertile (no pollinator needed), some partially self-fertile (will produce more reliably with a second tree of another variety), and some self-sterile (needs a different variety for cross-pollination).

 AZ Master Gardener Manual: Care (Cont.)
The fruit crops that respond to fruit thinning are peaches, plums, apricots, nectarines, apples, pears and grapes.
Pollination is the transfer of pollen (male part of flower) to the stigma (female part of flower) of a flower for fruit to set and seeds to develop.
Fruit trees that set fruit as the result of self-pollination are called self-fruitful.

 Fruit tree planting
As the stake is removed to dig the hole, difliculty arises in getting the tree in the position occupied by the stake, as very frequently the root system of the tree is such that the hole cannot be dug symmetrically.
The size of the hole for the tree depends upon three factors, extent of the root system, character of the soil, and height of heading.
Where one desires low-headed trees, and has been unable to secure them, the height of the head may be somewhat reduced by deep planting.

 Pruning fruit trees   (Site not responding. Last check: 2007-10-15)
The main aim when pruning fruit trees is usually to obtain a decent crop of fruit rather than a tree with an abundance of lush yet unproductive foliage.
Unpruned trees tend to produce large crops of small, worthless fruit often damaged by pests and diseases, and much of the crop is out of reach at the top of the tree.
A feathered maiden (that is, a one year old tree with several side branches) should have it’s main stem pruned back to three or four strong shoots at 30” from the ground.

 Pollination Is Essential In Home Orchard
These trees not only need pollen from another tree, but the tree must be of a different cultivar.
The tree may then self-abort some of the fruit in a natural thinning process sometimes called "June drop." The tree will drop many small-sized fruit at about the same time, making for a dramatic, and often alarming, show.
Unfortunately, these trees are often quite susceptible to winter and spring frost injury in Indiana, resulting in poor or no fruit crop most years.

 Royal Horticultural Society - Gardening Advice: Encouraging Good Fruit Pollination
Some trees, like 'Victoria' plum and 'Morello' and 'Stella' cherries, are self-fertile and set fruit with their own pollen.
However, the majority are self-incompatible and require pollination from a different cultivar of the same fruit type that flowers at the same time.
Choose a pollinating cultivar from the same group for preference, or one from the preceding or following group, as there is likely to be some overlap in the flowering period.
