In fact, it would almost be true to say that vegetative reproduction is the rule and not the exception. The goal of vegetative propagation is to reproduce progeny plants identical in genotypes to a single source plant. B. semperflorens ‘Link & Otto’ (wax begonia) is propagated from seed and marketed as a bedding plant. Answer: Begonia and Bryophyllum are examples of vegetative propagation by leaves. In general, however, limited research has been pursued with regard to stock plant temperature, suggesting that this could be a field for further research.

A particular group of begonias, called the rex begonias (Begonia rex cultorum), propagate themselves through leaf cuttings. Post a comment about this plant. The roots are often tuberous, and several species also reproduce vegetatively by production of bulbils, which detach to produce new plants. To propagate such a plant can be seed or vegetative (stems, leaf cuttings, division of the Bush or tuber or rhizome) way. The Cucurbitaceae are distinctive in being mostly monoecious or dioecious vines with simple, palmately veined and/ or lobed leaves, usually with tendrils, the female flowers epiperigynous, with usually parietal placentation and three carpels, the fruit a berry, pepo, capsule, or samara. As a result, science and technology has become a tool of transformation of human civilization and culture, both positive and negative impacts. K.
