outside artificial plants

The eggs of some normally sexually reproducing animals can be induced by artificial means to develop parthenogenetically. The stimuli inducing artificial parthenogenesis are salts, weak acids, organic solvents, urea, sucrose and physical stimuli like temperature, electric shock ..

Artificial Vegetative Propagation or Cloning - 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, th..

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 clo..

Summary - 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..

Hybridisation is the technique of introducing characters of two desirable plants into a single offspring (hybrid) by means of artificial pollination. This involves crossing of genetically dissimilar plants..

It refers to artificial propagation of plants vegetatively through the culture of cell or tissue. It is most useful, when normal propagation takes long time or the success in fertilization is very poor as seen in many valuable plants useful in agriculture, horticulture..

1. Colchicum autumnale yields an alkaloid colchicine, used for inducing polyploidy in plants artificially. 2. Urginea indica (White squill) - extract from bulbs used in making rat poison. fig. 27.16 Common Examples of Family Liliac..

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. Each embry..
