To obtain virus-free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?A. Apical meristem onlyB. Palisade parenchymaC. Both apical and axillary meristemsD. Epidermis only |
|
Answer» Correct Answer - C Both apical and axillary meristems are free of virus for healthy plant cultivation because of strong interferon activity in these region. These tissues form a protective impermeable covering around themselves, which is non-penetrable by any pathogen. Hence, these tissues are used in the production of disease-free plants by tissue culture. |
