Pollination required for the fruit production, vegetable and seed yields. Some plants are self pollinated. Some other plants usually pollinated by air. To transfer the pollen, many plants only depend insects.

What Is Pollination?

Many processes involved in obtaining marketable crops from the varied plant species used in the subtropics and tropics. Some have cultivated for thousands of years, and some only now being converted from wild forest crops to manage, sustained populations under cultivation. In a flower, a mature ovary develops the female gamete called ovum. Breeding is the development in sexual propagation, which follows pollination.

When male and female gametes are mature, the pollen grains from the anther transferred to the stigma of the pistil, by the way of air, insects, fowls or other beasts. This process of transference of pollen grains from the anther of stamen to the stigma of pistil called the pollination. The pollination is withered self or cross whether as transference of pollen grains take place within or two different flowers of same or different plants. When pollen transferred to another plant, the process named as cross-pollination.

In some plants, two sperm involved in conception; make contact with the ovule via a pollen tube from the germinating pollen grains. One sperm breeds the egg cell in the embryo sac to bring about the zygote and start the new reproduction. However, the other combines with the coalition cell to produce the endosperm, a particular tissue that supports at the developing embryo.  In fact, the Fertilization also arouses the growth of the guarding tissue (seed pod fruit) take care of the developing seed.  In Astros Plants, the fertilized egg cell grows through at different stages over the next 20 days until it assumes the shape of a mature quiescent embryo.

Few pollinators or pollination needs to considered despite knowledge that plants often need pollen transfer by creatures (other than by air, gravity and water). A European honey bee (Apis mellifera) extracts nectar from an Aster flower using its proboscis. While collecting nectar, bees move to several plant pollen is transferred from flower to flower. Certainly many plants need fairly specialized pollinators, such as the bats that pollinate the Duran of south East Asia. However, seemingly most crops pollinated by the specialized flower visitors found almost everywhere in the tropics, such as native sting less bees, honey bees, and in wide areas of the tropics, either in wild, not maintained populations, or in apiaries.

Just a few have reaped benefits surprisingly from purposeful introductions of chosen local pollinators. The extremely convenient domesticated crops that have pollinator need, the need for cross-pollination in seed and fruit production predominates and should receive greater attention as more crops raised commercially. The size and quality of the crop increased with the good pollinator service. It has become very clear that production could increase by careful management of pollination.

Importance of Pollination

Pollination is usually an ecosystem service that is nature provides for free. In some crops, the pollen has transferred from the male parts of the flower to the female parts of the same flower. In others, the transfer must between different flowers on the very flowering plant. And in still other crops the pollen has carried from the flowers of one variety to those of another.

    "If the bee vanishes from our world, living being would have four years to sustain. If there are no more bees, there is no more pollination. So there is no vegetation and no human being." ~Albert Einstein.

Einstein actually made this observation; it indicates the critical importance of pollinators for food security. And the entire ecosystems face threats, when the number of pollinators begins to decrease. Around the world, fruit, nut and crops are depending on pollinators for seed production. As pollinators move from plant-to-plant collecting nectar for their food source, they pass on pollen, which propagates the female parts of other plants.

The Pollinators:

Although nearly half of all beasts that pollinate plants are bees. Others are an extremely varied group. They include far-ranging bats and hawk moths, as well as tiny agaonid wasps and trips which are barely capable of sustained flight. Moreover the bees are amazingly varied over 95% all types have nothing to do with honey or colonies, and many of them build nests in the floor. The insects that visit flowers for food should include 10,000 of the species. The insects known as being of dominant influence in plant pollination are:


  • The Bumble Bee.
  • The Alfalfa Leaf cutter Bee
  • The Alkali Bee  
  • The Honey Bee

The Bumble Bee

The bumble-bee is effective in pollinating flowers in which its large size enables pollen transfer like cotton certain legumes and small fruit tree. Particularly, its long tongue makes it convenient in pollinating flowers with large sloppy corolla tubes from which only insects with long tongues can get nectar. Even though, bumblebees talented pollinators, they are typically scanty to pollinate large areas of crops.

Besides, their numbers vary randomly from place to place and from time to time so that even where they are quite large once they may inadequate to follow the area of pollination.  The practical use of bumble bees as pollinators restricted by their life cycle, smaller colony populations, and smaller domestication.

The Alfalfa Leaf-cutter Bee

The Alfalfa Leafcutter bee dominates a series of nesting sites containing beetle burrows nail holes and holes bored in the logs, or keeps the hollow stems drinking straws metal plastic and rubber tubes. Study of this insect being exposed and results that made its moneymaking value. Alfalfa leaf-cutter bees are proficient pollinators of specific crops, and their effectiveness has increased as controlling techniques enhanced.

The alfalfa leaf-cutter bees can now be bought in their pupa time and allowed to release, at the suitable time, to pollinate profit-making crops. The alfalfa Leafcutter bee is important pollinators of alfalfa, are extremely susceptible to pesticide poisoning. Time of day, rates of application, uses of insecticides, treatments in adjoining fields, and methods of application all affect this bee toxicity.

The Alkali Bees

The Alkali Bee limited to areas where the soil is sub soaked over a hard-pan layer which prevail on damp quite simple alkali places fitting for nest sites. By irrigating many regions and by planting an engaging host plant like alfalfa has extended a helping hand this species. Alkali bees develop yields of alfalfa seed due to scavenge the flowers among the lower foliage.

They also scavenge in scarcely any colder, windier climate than the leaf cutters. Alkali bees will fly up to 3 miles away when floral resources are not nearby. Growers who use these bees find that after the initial expenditure in bee beds, the management needs are minimized.

The Honey Bees

The Honey bees are the most popularly trusted pollinators. First attention is given here to the pollinating activities of the honey bee. Like other bees, they stop by flowers methodically getting nectar and pollen and do not hurt the flower by feeding on it in the pollination development.

Admitting that many species of bees help to crop pollination, an expected 80 percent of pollination made by the honey bee. Non-Apis bees are definitely more successful pollinators compared to Apis mellifera for some crops that rely on animal pollinators for fruit set, including alfalfa, blueberry and also cranberry. Growers generally import large numbers of honey bees, expecting that improving the frequency of encounters will increase the amount of productive pollination events.

We need to save the bees for sure.
