(d) In vegetative propagation, there is no genetic recombination, so the genetic constitution of a plant is unaffected in vegetative propagation. In ginger (Zingiber officinale), the means of vegetative propagation is fleshy, dorsiventral, horizontal, branched, underground, perennial, straggling rhizome (modified stem). Totipotency is the capability of any plant cell to develop into entirely new plant when provided with the suitable growing medium. it enables us to micropropagate plants. |
