Description

The invention relates to agriculture and can be used in plant breeding, if necessary, before the cutting of the stalks of cereal crops cut in the heading stage before the formation of grain.

The aim of the invention is to improve the quality of the seeds and thereby reduce the cost of the starting material per unit of production.

Example K A nutrient medium per 3 l was prepared, dosing the calculated amount of sucrose. 30 g of citric acid g and chloramine 0.9 g were added water to 3 liters and stirred until all ingredients were completely dissolved.

Table 1 shows the composition of the ingredients of the proposed nutrient medium.

The resulting medium was poured in portions of 0.30 l in laboratory vessels (o, 33 l), into which the stems were planted to grow: winter wheat cultivar Ilyichevka ;, roe wheat cultivar Mironovská rann; Bemid 1j winter variety of Nosovsky-9 variety of barmen;

The rest of the medium was stored in a refrigerator at a temperature of about in a closed vessel. The material for growing was prepared as follows from the experimental cases on the plants were selected, the grapes, the stems are in the phase of the earing and are cut off “„, counting from the top under the stream of water: 0–. 1.5 cm and put on the growth in the vessels with nutrient solution. From the stems 5 set to grow into the vessels, all the leaves were removed, except for the flag leaves, from which one third was left. As the cereals were reared, they were filled into the vessels 2-3 times with 0.2 l of the nutrient medium, to compensate for the natural evaporation and consumption of the medium for the formation of cereals. The optimum temperature for growing is 20012 C. After IO-J2 days, the used medium and bottoms of the vessels were poured out with freshly prepared nutrient medium, after having been rinsed with clean tap water with the addition of chloramine (per 1 / i water 0.5-0.6 g of chloramine), Change among the re-cut stems to 1.52, 5 cm

After 16-18 days, when the seeds reached the wax speleostig, the stems were removed from the vessels and dried

122

for 3-5 days at 18-22s. During the passage of the seeds of the rest period, laboratory analyzes were carried out to determine the sowing qualities of the seeds obtained {germination, weight 1000 seeds :).

Data analyzes are presented in table 2.

The material for growing and the preparation of a nutrient medium with varying concentrations of ingredients in the following examples were applied analogously to the first example.

Example 2. A nutrient medium per 3 l was prepared, the calculated amount of sucrose was 151.5 g, citric acid was 3.0 g and chloramine was 1.2 g. When analyzing the obtained material, the following data was obtained (see table 2),

Example 3 A nutrient medium was prepared based on 3 liters of water, 120 g of sucrose, 4.5 g of citric acid and 1.05 g of chloramine. As a result of the experiment, we obtained the following data (see table, 2).

Table 2 shows the quality parameters of the seeds obtained when growing cereal crops on an estimated medium in examples 1-3.

Table 3 shows the sowing qualities of seeds of various wheat varieties and depending on the composition of nutrient media in comparison with the prototype.

From the data of Table 3, it can be seen that when plants are grown in nutrient media prepared according to the ratios of the ingredients indicated in

tab. Seeds with high seed qualities were obtained.

Germination was 98.100.99% (prototype 15-50%), and the mass of 1000 seeds, respectively 16.0, 19.0 18.7 g

(prototype 5.4-12.4 g). The same media also had a higher shelf life of the nutrient medium with cultivated plants. ;

Thus, the data obtained indicate that the installed .-: Lenny range of ingredient concentrations allows to increase the seed sowing qualities and, in comparison with the prototype, the germination and weight of 1000 seeds is on average 2 times or more, to get homogeneous seeds by weight 1000 Sem N, increase shelf life

3

medium with cultivated plants for 2-3 days.

This nutrient medium for growing the cut stalks of cereal crops can be widely used in breeding centers and laboratories equipped with temperature and light control, as well as used for

conducting hybridization of cereal crops on a trimmed spike to obtain full hybrid seeds from crossing and for 5 preliminary propagation.

When applying the proposed nutrient medium, the cost of 1 m of protected ground is reduced by 23-27%
