Grafting of grapes in a split green shoots (Pict. 1) is the simplest technique to perform and quite reliable. As follows.
For the first sample on the same plant from the shoots left for grafting shears cut and remove all of the above the proposed vaccine. Wait 20-30 minutes (sometimes up to 2-3 h).
On the cut have to appear a drop of liquid (sap), which stands out most intensely in the morning and evening hours. Typically, a hot lunch time allocation sap stops.
If you do not drop stood out, the bushes should be abundantly watered, and shot put for a day or two.
When the sap stand out, proceed to the most vaccination. To do this, at the end of the shoot stock, which is released through the sap, make a longitudinal incision about 2 cm depth of the exact center. Then take the appropriate diameter graft scion, sharpened wedge-shaped bottom and inserted into an incision on the rootstock.
It is desirable that the wedge and the maximum cut is identical in size, then fusion would be better and better.
Pict. 1. Grafting in the splitting of green shoots
If the wedge is already a few cuts, then it can be shifted to one side, but then the fusion will be worse.
After combining the slices begin to coil. Take a strip of plastic tape or roller stretch film wrapped and vaccinated, from bottom to top and vice versa. There should be dense and tight coil.
If the vaccine is made by all the rules, then after 1-2 minutes (sometimes immediately) at the end of the scion to stand out the sap. This suggests that the vaccine is made qualitatively.
If the binding is tight and do not skip the juice, it must be repeated, ensuring that the sap has passed through the place of adhesions and performed at the end of the vaccination. It is important to ensure good root pressure sap stock (pre-watering, massive root system).
After that, the vaccine wear transparent plastic bag with a hole diameter of 5 mm for ventilation, tie the bottom package.
If there is a hot, sunny weather, vaccination should to shadow, since they can simply "boil" under the clear protective cap (pack) due to the greenhouse effect. Necessary to provide high humidity (100%) in the site of implantation for the entire period of accretion, about 2 weeks.
If the graft has taken root, then after about 12-14 days begins shoot growth of the scion. Open the protective package must not before escaping to reach a length of 5 cm or more, after loosening the eyeballs at the bottom of the package, and be sure to shadow escape in the first week after removal of the protective bag. When the vaccine reach 15 cm, you can remove the shading.
Remove harness vaccines do not hurry, do it through 1 to 1.5 months after vaccination, when the coil starts to cut into the growing vaccine. Circuitry can be reduced by 3 weeks, but this should be done cautiously. Growing shoots of the scion as soon as possible to fix the pole, during the growing season to protect against disease.
Thus, with a number of powerful 1 -, 2 - and 3-year rootstock bushes, you can introduce new products as grape selection on your site, the next year to get the first harvest and a realistic assessment of a new variety.
After 2-3 weeks (sometimes up to 30-40 days) after vaccination stepchildren should start to rise. Grow faster those vaccinations that are made of lignified cuttings. But the quality of fusion better when grafted scion green on green shoot stock.
If by that time, the growth processes are not observed, and the leaves are green and stepchildren on vaccinations shrunken, it is likely the vaccine failed, and it should be repeated.
