Detailed explanation-1: -Rose plant is cultivated by stem cutting. This is an asexual method of reproduction. Good stems are selected and dipped in auxin hormone that promotes root formation. These stems are then planted in a medium to obtain plants that are genetically identical to the parent plant.

Detailed explanation-2: -The asexual reproduction in rose plants can occur through the stem cuttings. The new rose plant formed from the cutting is similar to the parent plant, thus rose plants are commonly grown by this method.

Detailed explanation-3: -Introduction. Asexual reproduction of roses by stem cuttings is probably the simplest method of propagating roses. Most old roses, English roses, miniatures and some rootstocks are commonly propagated by cuttings because they can easily form roots and, further, they grow vigorously on their own roots.

Detailed explanation-4: -vegetative reproduction, any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure (such as a stolon, rhizome, tuber, corm, or bulb).
