Cross-pollination-The movement of pollen from one flower to another, either on the same plant, between different plants of the same cultivar, between plants of different cultivars, and sometimes between plants of different species.

Cross-pollination-The transfer of pollen from the flower of one plant to the flower of another for the purpose of fertilization. This can occur in nature or with human intervention.

cross-pollination The fertilization of a ovary on one plant with pollen from another plant, producing an offspring with a genetic makeup distinct from that of either parent. See pollenizer.

What Is Cross-Pollination?
Cross-pollination is the transfer of pollen from the flower of one plant to the flower of another individual to fertilize it. Often this is accomplished by an insect or other animal pollinator.

Cross-pollination: transferring pollen from the flowers of one plant of a species to the of another plant of the same species.
Deficiency. See .
Dioecious: varieties or species with male and female flowers on separate plants.

Cross-Pollination
When pollen transfers from the flower of one plant to that of another. Generally used to refer to a situation where varieties mix by such means.

Cross-pollination doesn't mean that you will end up with weird-looking hybrid fruits.

This is a cross-pollination issue on one hand (see the fennel and dill warning above) and a companion planting issue on the other.

Speaking of pollination, corn is wind-pollinated, and cross-pollination can occur if not careful. Supersweet varieties are especially susceptible to cross-pollination and should be isolated from other varieties.

Species that rely on cross-pollination, however, require the same or a closely related species blooming at the same time to yield a crop of edible fruit.

Another way to avoid cross-pollination is to choose plants that mature at different times. A certain amount of natural crossing can be acceptable. It may sometimes even result in an improved plant.

To produce nuts, you need at least two varieties for cross-pollination. And while they can make a good shade tree, harvesting quality nuts in a home situation can be tricky.

Plant two different varieties of blueberries to ensure cross-pollination. A single blueberry plant will produce fruit, but the yields will be higher and the fruits bigger if more than one plant is grown.

Bluecrop and Berkeley highbush blueberry (Vaccinium darrowi 'Blue Crop' and 'Berkeley', two each of two cultivars for cross-pollination, plant 3-1/2 feet apart in acidic soil
F.

Be aware that if you want cross-pollination to occur in your garden, you need to make your garden favorable to pollinating insects or be prepared to do all the pollinating yourself.

Most peaches grown in Colorado don't need cross-pollination. Recommended peach varieties for Colorado are Elberta, Haven, Polly, Reliance, Hale Haven and Ranger. Peaches needing cross-pollination are J.H.

Blueberries are partially self-fertile, which means they bear some fruit without cross-pollination. But when at least two different varieties grow near each other, yield is higher and fruits are larger.

Two different apple varieties that flower at the same time are needed for cross-pollination; a crabapple will also do the job.

When cross-pollination occurs between genetically widely different plants, the resulting embryo may be aborted because of parental mutual incompatibility. Such embryos may be excised and grown on a congenial medium such as nutrient agar.

When doing elderberry planting, you want to make sure you allow for cross-pollination. Therefore, two or more cultivars can be planted near each other. This allows for the necessary cross-pollination.

It is self-pollinating, so it does not require another tree for cross-pollination. It should be fertilised much like an apple tree, and applications of organic matter around the drip line of the tree will be most beneficial.

Beware of cross-pollination of different varieties, which can result in tough, starchy kernels.

Furthermore, don't use insecticides when the trees are blooming, as bees are essential to cross-pollination.

Note to Seed Savers: Wind pollination also results in easy cross-pollination, so keep different types of corn separated by at least 25 feet or plant varieties that mature at different times.

Plant at least two blueberry varieties to ensure adequate cross-pollination. The listed varieties are all of the rabbiteye type. Other types of blueberries are not well adapted to Texas.

pollinizer. The producer of pollen; the variety used as a source of pollen for cross-pollination.
pome fruit. A simple fleshy fruit, the outer portion of which is formed by the floral parts that surround the ovary.

The only problem is if you have grown more than one variety of cucumber. Then cross-pollination could mean that the cucumbers aren't the same as the ones on the original plant. (They might not be as good).
Anyway, you can see what happens ...

These tend to be self-pollinated plants like tomatoes, most flowers and beans. Grow these plants until they produce harvestable seed. Take care to arrange your garden so as to reduce cross-pollination between different varieties of the same flower ...

damaging health effects from manipulated food crops. When new genetic information is introduced into plants, bacteria, insects, or animals, it can then be passed into related organisms through naturally occurring processes such as cross-pollination.
