Description

The invention relates to agriculture, namely to viticulture. A method of preserving grafted cuttings of grapes to stratification is known, including treating the junction of copulation sections with an antiseptic solution and storing grafted cuttings at a temperature below the developmental temperature and relative humidity of 85-90. The treatment with an antiseptic is carried out about once by dipping the upper part of the grafted cuttings, including the place where the copulative cuts join, into an antiseptic solution, after which the cuttings are waxed, stratified with steam, sawdust and stratified to stratification 1. The disadvantage of this method is the large loss of plastic substances during storage of grafted cuttings and the low yield of viable grafted cuttings after their preservation. The purpose of the invention is to reduce the loss of plastic substances and increase the yield of viable grafted grafts. The goal is achieved by the fact that in the method of preserving grafted grapes cuttings before stratification by treating them with an antiseptic and storing them at a temperature below the temperature that ensures development, and at a relative humidity of 8590, the treatment is carried out by immersion in the antiseptic solution of the upper parts of grafted cuttings, including the place of the junction cuts and subsequent storage therein over the entire storage period. EXAMPLE 1. Vaccinations made in winter (December, February and the first half of March) put 3 upper suits (grafts) in a cold antiseptic solution, for example, an electrolytic solution of silver, to a depth of cm, including the bottom section. slices. To prevent the drying of the lower parts, the GROUND ambient air humidity in the premises is maintained at 8590- at. When the time of stratification comes, the grafted cuttings turn upside down with their upper ends up, and their lower ends down in the room raise the temperature to 30, and the air humidity is adjusted to 100. 3 Copulative sections that are in an antiseptic solution, for example, in an electrolytic silver solution, are not are oxidized, do not dry out and are not affected by fungal diseases. Example 2. Grafted cuttings (Galan on Kober 5BB) are preserved according to the known and proposed methods. The results of the conservation of pre-stratification by a known method on the regeneration processes and the yield of seedlings are given in Table. 1 (Galan on Cober 5BB, average for 1978-1979).

The lower yield of grafts with a circular callus and a spreading eye after preservation by a known method in comparison with the control variant is explained by both the oxidation of the surface of the sections and the clearing of the kidneys in the eyes during the preservation period.

Claims (1)

Claim The method of preservation of grafted grafts cuttings prior to stratification by VNIIIPI Order 11988/3 S3 processing them with an antiseptic and storage at a temperature below the temperature that ensures development, and with a relative humidity of 85-90%, characterized in that, in order to reduce the loss of plastic substances and increase the yield of viable grafted cuttings, the treatment is carried out by immersing the upper antiseptic in solution parts of grafted cuttings, including the junction of copulation sections, and subsequent aging in it during the entire storage period.
