artificial method

In this process semen is collected from a bull of desirable breed and stored at freezing temperature. This semen is injected into the vagina of cows during the period of heat of the animal, for fertilization. This method has many advantages. As many as 3000 cows can be fertilized by th..

Certain flowering plants have the capacity to develop a part of their somatic body into a new independent plant. In artificial vegetative propagation, such plants are identified and special techniques are applied to obtain new independent plant. Horticulture have used the various met..

Vegetative propagation produces the next generation that is genetically identical to the parent. Such an organism that is genetically identical to the parent is called a clone. In case of plants with advantageous characteristics, the characteristics can be preserved by producing clones. This is par..

Reproduction occurs by vegetative propagation, asexual and sexual reproduction. Vegetative propagation through artificial method can be done by cuttings, layering and grafting. Pollination refers to the transference of pollen grains from the anther of a flower to the stigma of t..

Modes of reproduction in plants can be grouped into 2 types a) asexual b) sexual reproduction Regeneration of new plants from portions of vegetative organs is very common. Runner, rhizome, bulbs, corns and tubers serve as means of propagation. A population of genetically identical plants..

In this method embryos are generated artificially by somatic cells carrying 2n chromosomes as against embryos normally produced in nature by gametes carrying chromosomes. These embryos are called embryoids . They are grown in large number in a small volume of nutrient medium. ..

The petrol obtained artificially from coal as a mixture of alkanes resembling petroleum like aliphatic hydrocarbon fuels is called synthetic petrol. Two important methods for producing synthetic petrol are the Fischer-Tropsch process and the Bergius process. These processe..

Synthetic Petrol (Aliphatic hydrocarbons from coal) - The petrol obtained artificially from coal as a mixture of alkanes resembling petroleum like aliphatic hydrocarbon fuels is called synthetic petrol. Two important methods for producing synthetic petrol are the Fischer-Tropsch..

Asexual Reproduction - New individuals are produced from a single parent without the act of fusion of gametes. The new individuals so formed are generally identical to the parent plant, as only mitotic divisions take place during their development. Regeneration of new plants from portions of vegeta..
