Question

write a note on Natural vegetation propagation​

Answer 1

Natural vegetative propagation

• Natural vegetative propagation occurs when an axillary bud grows into a lateral shoot and develops its own roots (also known as adventitious roots). Plant structures allowing natural vegetative propagation include bulbs, rhizomes, stolons and tubers.

Bulbs

• Bulbs, such as daffodils, form lateral buds from the base of the mother bulb, which produce new smaller bulbs or bulbels in subsequent years.

Rhizomes

• Rhizomes are root-like stems that grow horizontally under the ground. New roots and shoots form at the nodes with shoots growing upwards to form new plantlets. Lateral buds grow out to form new rhizomes. Examples include iris and root ginger.

Stolons

• Stolons or runners are horizontal stems that grow above the ground, for example, strawberries. Tiny plantlets form along the stolon, and roots form where they touch the ground. When the connection with the parent plant breaks, the new plant becomes independent.

Tubers

• Tubers are swollen portions of an underground stem that store food so a plant can lie dormant over the winter, for example, potatoes. Axillary buds, commonly known as ‘eyes’, form over the surface of the tuber and produce shoots that gro.w into a new plant the following year.

NOTE:

Plant propagation is the process of increasing the number of plants of a particular species or cultivar. Propagation can be via s e x ual or asexual means. Over the years, horticulturalists have developed as exual propagation methods that use vegetative plant parts. This allows plants to be created in ways that nature cannot duplicate.

ADDITIONAL INFORMATION:

Asexual or vegetative plant propagation

Asexual or vegetative plant propagationAsexual plant propagation methods produce new plants from vegetative parts of the original plant, such as the leaves, stems and roots. These methods are generally referred to as vegetative propagation. Many plants can reproduce this way naturally, but vegetative propagation can also be artificially induced.

Advantages of vegetative propagation

• The main advantage of vegetative propagation methods is that the new plants contain the genetic material of only one parent, so they are essentially clones of the parent plant.

Disadvantages of vegetative propagation

• The main disadvantage is the potential to impact on biodiversity of a species. Also, if a particular plant clone is susceptible to certain diseases, there is potential to lose entire crops

Answer 2

Answer:

Smoking causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. Smoking also increases risk for tuberculosis, certain eye diseases, and problems of the immune system, including rheumatoid arthritis.Smoking causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis.
