Unfortunately, apples trees and pear trees cannot pollinate one another. You need to pollinate your apple and pear trees separately to produce fruits.

Question 6

Maize plants contain both male and female reproductive structures and reproduce by both cross-pollination and self-pollination.

Most modern hybrids are not the product of pollination in the wild. Hibiscus breeders intentionally cross plants to produce new colors and blossom shapes. For example, if a genetically pure white hibiscus is pollinated by a genetically pure red hibiscus, the result will be seeds that will grow a pink hibiscus.

Nearly all common varieties of apricot, peach, nectarine and sour cherry are self-pollinating. Other fruit trees, like most apple, plum, sweet cherry and pears are cross-pollinating or self-unfruitful.

If you think about the apples that you can find frequently at a grocery store, the top sweet apple is Fuji. The sugar levels in a Fuji apple range from 15-18 on average (remember, an apple is mostly made up of water).

A Pink Lady® apple provides 54Kcal/100gr. It is rich in fibre and contains 10% carbohydrates. It is an excellent, and natural, appetite suppressant.

Pink Lady® Apples was the first apple with a trademark! Pink Lady® was the first apple to be awarded a trademarked name. Growers like Stemilt must obtain a license in order to grow, pack and market this apple variety under the Pink Lady® name.

Australia is renowned as the first country to have grown Cripps Pink and the owner of the Pink Lady® brand. The stunning Southern Forests region of Western Australia is home to the Giblett, Mercer and Newton families – some of the first growers of Pink Lady® apples in the world.

Sour cherry trees are more resistant to disease than sweet cherries. Montmorency cherries are the most popular sour cherries grown in the country, according to the Colorado State University Cooperative Extension. These reliable fruit producers also have a high resistance to disease.

5 Disease Resistant Trees

• Japanese maple (Acer palmatum):
• Chinese Fringe Tree (Chionanthus retusus):
• Magnolia (Magnolia sp.):
• Chinese Pistache (Pistacia chinensis):
• Bald Cypress (Taxodium sp.):

Standard-size trees will bear in 5 to 8 years, yielding 4 to 5 bushels of apples per year. The variety of apple selected should be based on fruit characteristics, bloom time, and pollen compatibility.

For the most part, apples can’t pollinate themselves. Most varieties of apple are dioecious, and there’s nothing we can do about it. If you want to grow an apple, you are going to have to plant a neighboring apple tree.

They have to hand pollinate fruit in some regions of China. In a remote area in China, humans pollinate 100% of fruit trees by hand. Armed with pollen-loaded paintbrushes and cigarette filters, people swarm around pear and apple trees in spring. The reason why they hand pollinate is not what you think, though.

In the coming years, populations of bees, butterflies, and other pollinating species could face extinction due to habitat loss, pollution, pesticides and climate change. It’s possible human pollination can actually cost less than renting bees to pollinate crops.

Hand pollination, also known as mechanical pollination is a technique that can be used to pollinate plants when natural or open pollination is either undesirable or insufficient.

Self-pollination refers to a type of pollination wherein the pollen from the anther is transferred to the stigma of a single flower. Flowers that carry out self-pollination are hermaphrodite. A hermaphrodite flower is one in which both the stamen and the carpel are present.

Examples. Arum lilies, tridax (part of the daisy family) and some orchids are self-pollinating flowers. Dates, box-elder and buffalo berry are self-pollinating flowering trees. There are quite a few vegetables that self-pollinate, such as tomatoes, okra, peas, snap peas, soybeans and lima beans.

Example. Pumpkins, grapes, grasses, apples, maple trees, daffodils and more. Chasmogamous flowers that facilitate cross-pollination. They develop exposed anthers and stigma.

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Cross-pollination is the process of applying pollen from one flower to the pistils of another flower. Pollination occurs in nature with the help of insects and wind. This process can also be done by hand to produce offspring with desired traits, such as colour or pest resistance.

Pollination: Pollination is the process of transfer of pollen grains from anther to stigma. The two types of pollination found in flowering plants are: Self pollination: that occurs within the same plant. Cross-pollination: that occurs between two flowers of two different plants but of the same kind.

: the transfer of pollen from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone)

Self-pollination happens when a plant transfers its own pollen from the stamen to the pistil by itself (these terms are explained below). It does not need the help of bees, hummingbirds, butterflies or other insects.

noun Botany. the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone.

May lead to the weakening of variety or the species due to continued self-pollination, thereby affecting the quality of offspring. Defective or weaker characters of the variety or breed cannot be eliminated. Self-pollination does not yield new varieties, hence fewer chances of improvement in the subsequent generation.

Some plants have evolved to have self-incompatibility mechanisms to avoid self-pollination. A physiological barrier makes it difficult or impossible for a flower to fertilize itself even though it may have been abundantly pollinated with its own pollen.

There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm.

The adaptations appear in the self pollinated plants are Cleistogamy, Homogamy, Movement of floral parts, Incomplete dichogamy, safety mechanism. Cross-pollination is the transfer of pollen to stigma to another flowers of another plant same species.

The contrivances for cross pollination

• Dicliny or unisexuality: Flowers are unisexual.
• Self-sterility: In this condition, pollen grains from the same flower or any flower of the same strain does not have any effect on the stigma.
• Dichogamy:
• Herkogamy:
• Heterostyly:
• Advantages:
• Disadvantages:

Pollination occurs when the male pollen lands on the sticky, female stigma. To some extent plants can control pollination, often to encourage cross-pollination. They may do this, for example, by the stigma ripening and becoming receptive to pollen before the pollen in the same plant is ripe.

This transfer of pollen from one flower to another is called cross-pollination. If the pollen is transferred to the stigma of the same flower it is called self-pollination. Pollen grains are also adapted for insect pollination. Some pollen grains are hairy or spiky, and others are sticky, so they attach to the insect.

Advantages of cross-pollination: – Genetics recombination- as the pollination occurs between flowers of two different plants this results in the origin of new varieties. It helps in evolution. -The offspring produced through cross-pollination is healthy, viable, and stronger (resistant) due to hybrid vigour.

Advantages of cross pollination: The offspring are healthier. The seeds are produced in larger number and are more viable. The seeds develop and germinate properly and grow into better plants.

When the blossom is out insects, such as bees, are therefore able to cross-pollinate the trees as they buzz around looking for pollen. Even trees that are self-fertile will produce better quality fruit in the presence of a pollinator.
