Explanation:
Vegetative propagation:
Vegetative propagation is a method of asexual reproduction in plants where new plants are produced from vegetative parts such as leaves, stems, and roots, without the involvement of seeds. There are various methods of vegetative propagation, including cutting, layering, grafting, and tissue culture.
Statement a) Plant grown by vegetative propagation are not prone to diseases:
This statement is incorrect. Plants grown by vegetative propagation are not immune to diseases. In fact, the risk of diseases can be higher in plants propagated vegetatively. This is because the new plants produced through vegetative propagation are genetically identical to the parent plant. Therefore, if the parent plant is susceptible to a particular disease, the propagated plant will also be susceptible to the same disease. This lack of genetic diversity can make the plants more vulnerable to diseases.
Statement b) Plant raised by vegetative propagation can bear flowers and traits earlier than those produced from seeds:
This statement is correct. When plants are propagated vegetatively, they retain all the characteristics of the parent plant, including the ability to flower and exhibit specific traits. Since the new plant is a direct clone of the parent, it can start flowering at an earlier stage compared to plants grown from seeds. This is particularly advantageous in horticulture, as it allows growers to produce flowering plants with desired traits in a shorter period of time.
Statement c) Plants grown using tissue culture technique are highly prone to diseases:
This statement is incorrect. Tissue culture is a technique used for the mass production of plants under sterile conditions. During tissue culture, plant cells or tissues are grown in a nutrient-rich medium in vitro. This technique allows for the production of disease-free and genetically identical plants. The sterile conditions in tissue culture minimize the risk of diseases, as pathogens are eliminated or controlled. Therefore, plants grown using tissue culture technique are relatively less prone to diseases compared to plants propagated through other methods.
Conclusion:
The correct statement is option 'D'. Plants grown by vegetative propagation are not immune to diseases, but they can bear flowers and traits earlier than those produced from seeds. Plants grown using tissue culture technique are less prone to diseases due to the sterile conditions in which they are produced.
