Abstract

The invention relates to agriculture and can be used in the vegetative propagation of gooseberry plants. The purpose of the invention is to increase the rooting rate of cuttings, improve their quality and survival rate when transplanted into open ground. During the active growth of shoots, uterine gooseberry bushes are treated with a physiologically active substance, which is used as 2-chloroethylphosphonic acid in a concentration of 0.015-0.050% of the active substance, while green cuttings are planted for rooting immediately after they are cut from the mother plant. 2 tab.

Description

AND

The invention relates to agriculture and can be used in the vegetative propagation of gooseberry plants.

The purpose of the invention is to increase the rooting rate of cuttings, improve their quality and survival rate when transplanted into open ground.

Non-uterine gooseberry plants of difficult-to-cultivate varieties as a means of increasing the rootedness and quality of cuttings, use the preparation HEPFK (2-chloroethylphosphonic acid) in a concentration of 0.015-0.025% of active ingredient (ae). Preparative form - 50% aqueous solution. Structural formulas, -sn, -r-on,

mol.m. 144.5. Transparent, odorless liquid, density 1.25 g / cm3. It is well dissolved in water, pH 1% aqueous solution 1.6. In an alkaline environment, decomposes, separating ethylene. The drug is incombustible, inexplicable. Ma- I is a lotto-toxic substance. For two rats and mice more than 4000 mg / kg, it does not cause temporary irritation of the mucous membranes. Embryotoxic. no mutagenic and carcinogenic effect. The MPC in the water of reservoirs is 4 mg / l on the basis of sanitary toxic signs of harm. Practically non-toxic for beneficial insects and fish.

PRI me R. During the period of intensive growth of shoots (end of mother), 2-3 weeks before grafting, uterine plants are treated with an aqueous solution of CEPA of various concentrations. Cuttings are planted on the dock

rendered to the substrate on the day of grafting without auxin treatment (ft-IMC).

Some of the test cuttings are treated in a known manner, according to which the uterine plant is treated with a 1-1.5% aqueous solution of chlorine chloride (XXX) at the beginning of intensive shoot growth. After spraying uterine plants, cuttings are cut, bundled and placed in auxin solution (/ 3-IMC, 25-50 mg / l) for 18-24 hours. Then, the cuttings are washed with running water and planted in ropes for rooting fogging installation.

As an object, the May Duke gooseberry variety was chosen, which is distinguished by high yield, large years of dessert taste, as well as an extremely low percentage of rooting and poor development of the root system, which is typical of most varieties of European origin. This leads to the massive death of rooted cuttings when transplanted into the open ground in autumn and is the main reason for the lack of planting material of valuable gooseberry varieties.

In tab. Figures 1 and 2 show that the treatment of mother plants of the gooseberry CEPA at a concentration of 0.015–0.050% in d. without subsequent processing of the cuttings themselves in the IMC, it allows not only increasing labor productivity, simplifying the technology,

but also dramatically increase the efficiency of reproduction of valuable varieties with low root-forming ability.

Root growth increases to 70–74% (against 4–5% in control), while rooted cuttings differ in alignment and good development (the number, root length, weight, branching order) increase, which undoubtedly ensures good survival rate during transplantation in open ground. The use of lower doses of the working solution compared with the known method reduces the risk of environmental pollution.
