Apple trees with desirable characteristics, such as a particularly tasty fruit, are often grafted onto hardy, disease-resistant rootstock from another variety to produce an overall sturdy and highly productive tree. 15. The rootstocks themselves are propagated by cloning techniques to preserve these desirable characteristics. Mound layering. Roots will develop at the bases of the young shoots. Tip layer rooting of plants is most commonly used on plants that grow canes, such as blackberries, raspberries, and roses. These new shoots are removed and placed in their own container of media to continue the rapid proliferation of rootstock. Continuous/Trench Layering Air layering Mound/ Stool layering Of these, the most commercially important are mound layering for multiplication of rootstocks and air layering for some tropical fruits. Layering is also utilized by horticulturists to propagate desirable plants. This is to ensure that we give you the best experience possible. The base of each segment is treated with a dilute solution of indol-3-butyric acid, or IBA, and auxin in water to accelerate root formation, then stored in peat moss for up to three weeks before planting.

Joshua Bush has been writing from Charlottesville, Va., since 2006, specializing in science and culture. Layering has evolved as a common means of vegetative propagation of numerous species in natural environments. propagated by mound layering. The following spring, soil is mounded over the young shoots growing from the buds in order for roots to develop. Micropropagation, or in-vitro plant tissue culture, has only recently become economically competitive with other propagation methods. Mound (stool) layering is useful with heavy-stemmed, closely branched shrubs and rootstocks of tree fruits. It was suggested that SRSC was the most suitable material for “M.9” apple root propagation by mound layering, but as SRSC needs watering twice a day R + S could be used alternately. The central leader and branches are bent down and secured into a trench that is dug beneath the tree. By early winter, these new shoots will have produced roots of their own.
