All shoots sprouting from the stock should be removed otherwise they will not permit the scion to grow. Stem tubers arise from rhizomes or runners that become swollen from storing nutrients.
Cuttings A cutting is a piece that has been cut off a mother plant and then caused to grow into a whole plant. Over the years, horticulturalists have developed asexual propagation methods that use vegetative plant parts. This forms the new plants in the next season.
Vegetative propagation by stems: Straggling and branched rhizomes reproduce by vegetative reproduction e.
Corms differ from bulbs in that their centers consists of solid tissue while bulbs consist of layered leaves. Fragmentation Segmented worms and many echinoderms such as starfish reproduce asexually via fragmentation.
Grafting: Grafting is an artificial method of asexual reproduction used to produce plants combining favorable stem characteristics with favorable root characteristics.
Given an environment suitable for life, the spores will then develop into fully grown organisms and eventually grow their own spores, repeating the cycle. Layering Figure 3. This method is widely practised in rose, plums, etc. This is often associated with r-strategists. Most plant species that survive and significantly expand by vegetative reproduction would be perennial almost by definition, since specialized organs of vegetative reproduction, like seeds of annuals, serve to survive seasonally harsh conditions.
