Receiving new plant from some part of old – for example, shanks, leaves, roots, is called vegetative. The most widespread the way of reproduction is considered cherenkovaniye.
In decorative gardening, floriculture the reproduction of plants is rather widely applied by shanks. It is preferred to be used when it is impossible to achieve early blossoming at reproduction by seeds, at reproduction of terry (full-color) forms of plants where seeds are not formed or them it is possible to receive in very small amount, and in other cases.
What is shank
Shanks represent part of stalk, root or leaf which should be placed in the most suitable conditions for formation of roots. After receiving backs the shank develops in new plant. Shanks can be sheet, root or sheet.
Root shanks receive in the following way. In the fall or in the spring roots cut 4 or 5 centimeters on separate pieces. Their thickness has to be defined depending on species of plant. The most suitable it is possible to consider shanks thickness about finger or about pencil. It is necessary to land them vertically, capacity has to be filled with mix of the peat and sand-cespitose earth. It is better to keep them in the warm place, for example, in hotbed or greenhouse under racks, after germination it is better to take out them on light. It is possible to replace young plants in small pots where they will grow till spring or fall of the next year. Stem shanks take generally from the top branches.
What influences rooting of shanks
Rooting of shanks is influenced significantly by lighting. If they have at least small piece of leaf, rooting will require light. The shank deprived of leaves takes roots in the dark better. Besides, it is better to remove leaves as much as possible also because through them a lot of moisture leaves. Shanks, especially weak, begin to dry. Landed in light ware, they will take roots much worse, than when landing in dark. Some shanks well take roots during dormant period. A lot of things when rooting depend on from what plant shanks are cut off as it was fertilized. At total absence of fertilizing for maternal plant the rooting will be complicated. When receiving fertilizing with the increased nitrogen content – almost the same. In order that well there took place formation of new roots, for maternal plant of fertilizer have to contain a lot of potassium, phosphorus, it is not enough nitrogen. Cuts from old plants cherenkutsya very badly. At cuts from young people the cherenkovaniye passes much better, even without processing by korneobrazovaniye stimulators. Processing is optional to those plant species which already differ in good rooting, and the age of maternal plant does not matter at all.
