Especially often this happens with begonias, because they have so many varieties and varieties. Therefore, the owners of these beauties need to quickly get a young copy.
Methods of breeding begonias
Depending on the species, begonias can be propagated:
- seeds( all flowering species);
- division of tubers( tuberous species);
- leaf cuttings and parts of the sheet;
- stem cuttings( any begonias that have a stem).
Seed propagation is the longest and most unreliable method. It is suitable when there is no material for vegetative propagation or when you need to get a large number of plants. Due to the nature of the plant, the process of sowing and germination is rather complicated.
Vegetative reproduction ensures the preservation of all the features of the parent specimen.
When using leaf cuttings of begonia or parts of its sheet, babies are formed that develop as slowly as sowing seeds.
Benefits of stalk cuttings of begonia
Cutting of begonias with stem parts is preferable to other breeding methods because this variant:
The rooted begonia stalk can be up to 15 cm tall. At this point, it becomes quite strong and will continue to grow at the same rate as the parent. Flowering, depending on the species, can come almost immediately. The percentage of surviving cuttings of begonias is usually very large.
The reproduction of begonias with stem cuttings, thanks to obtaining identical mother specimens, makes it possible to preserve the gene pool of especially valuable varieties and varieties.
With the observance of technology, the method of cuttings of begonia does not cause trouble for the plant grower.
Virtually any begonia is easily reproducible by stem cuttings. Even in the royal begonias, reproduction by cuttings is possible if the old specimens are cut off the tip, which has not yet had time to become a rhizome.
reproduction technology begonias stem cuttings
Cuttings begonias includes such steps:
- slicing and preparation of cuttings,
- drying sections,
- rooting,
- landing rooted stalks.
For cutting, use pieces of healthy stems 8-12 cm long. Cuttings can be apical( taken from the tip of the stem of the plant) and median. In any case, at least two to three buds should remain on them. Extra leaves are removed so that they do not take power from the germ. It is enough to leave 1-2 leaves. After this, the cuts should be slightly dried.
There are two ways to root the cuttings of begonia: in water and in the substrate.
In the first case, the lower part of the prepared cuttings of begonias is placed in a vessel with soft water at room temperature. Hard or cold water should not be used. The vessel is placed in a moderately warm( 18-20 degrees), bright, but not in direct sun place. After that, it remains to be patient and observe. .. If the capacity is transparent, then the state of the slice will be clearly visible. Thus, the plant breeder will not miss the moment of appearance of the first roots and planting time. In addition, you can notice in time if the cutting of the cutting began to rot. Then it is removed from the water, cut off the damaged place, dried again and placed in fresh water. After the appearance of roots of 1-2 cm in size, the cuttings are planted in a suitable soil and then act as after a normal transplant.
Rooting begonia can also be rooted in the substrate, which can be used as wet peat, sand or primer suitable for begonia. In this case, a section of the prepared cutting is dipped into water, and then into a special preparation that facilitates the formation of roots( root, heteroauxin, or some other).
In a small pot( in accordance with the size of the cutting) a suitable wet substrate is poured onto the drainage. The cutting should be inserted into the ground, deepening the cut by 1-2 cm.
After this, the pot is tightly covered with a transparent jar or placed in a tight-fitting transparent container that fits in size. No part of the plant should not touch the walls or the roof of the greenhouse.
After some time, perspiration will appear on the container walls. This suggests the formation of a suitable microclimate. Then - every day for a moment you need to open the greenhouse for airing and watch. As soon as new leaves appear, the greenhouse is removed. A new plant is ready.
You can use any of the methods described. In the water it is more convenient to observe the process of the formation of roots. This method is more familiar. But the roots are formed fragile, they are usually injured when planted. And the plant has to adapt to new habitat conditions. The process of engraftment and growth slow down, begonia weakens.
When rooting in the soil, the roots are immediately adapted to extract moisture and nourish it. As a result, the plant obtained in this way overtakes the growth of its "water" counterparts.
