Description

Example 2. The effect of cis-o-8-mentene on red radish plants with a white tip was studied under field conditions on sod-weakly podzolic medium loamy soils. Before sowing, the seeds were soaked for 12 hours in a 0.001% aqueous solution, while the controls were soaked in tap water. Table 2 shows data on the effect of the cis-o-8-mentene on the radish crop. Presowing treatment of seeds with cis-o-8-mentene increases the yield of the radish plants. Example 3- Tomato seeds and Gribovsky soil of 1180 were soaked for 12 hours in a 0.001% cis-o-8-manthen rape, followed by germination on sod-weakly podzolic medium loamy soils. A mixture of unsaturated bicyclic formyl derivatives was used as a reference. The results of the experiments are given in tabLoZ. The use of cis-o-8-mentene for the pre-sowing treatment of the seed of a tomato strengthens the plant, process, increases the number of brushes and flowers and contributes to an increase in the yield of fruits. Example 4. Before planting, cuttings of hops were processed by immersing in 0, cis-o-8-menena solution for 12 c. Treated grafts were immediately planted into the ground on the plantation of hops. Table 4 presents data on the effect of cis-o-8-mentene on the yield of various hop varieties in the year of planting. Example 5. Stimulation is performed on buckwheat seeds of the Shgtilovsk 4 variety by soaking them for 1.2 and 4 hours in the solutions of the preparation 0.005, 0.001, 0.0005 and, 0, concentration; Counter-soaked in water for the same time seeds. The results of the experiments are given in Table 5. Table 5 presents data on the effect of cis-o-8-mentene on the sowing qualities of buckwheat seeds. Soaking for 1-2 hours in solutions of 0, the concentration of cis O-8 menten increases the energy of seed germination by 2-8, and germination - by. Longer soaking in drug solutions (up to k h) reduces both germination energy and seed germination, however, these indicators are higher than those of the control variants {water treatment). In another series of experiments, the seeds of buckwheat were treated with water (control), solutions of p-3-mentene in a mixture of unsaturated bicyclic formyl derivatives (reference preparations) and cis-o-8-mentene for 1 and 2 hours. The results of the experiments are given in Table. 6 Example 6. Stimulation is carried out on cruciferous forage seeds, winter rapeseed (population VIC) and rapeseed (variety Latvian 10) by soaking them in cis-o-8-mcnthen and p-3 menten solutions for k h after then the seeds were washed in tap water and germinated in Petri dishes D bed on filter paper. The results of the experiments are given in tablo; The treatment of winter rape seeds with a 0.0005% solution of cis o-8-mentene increases the germination energy in comparison with the control variant and the reference preparation, respectively, by 9 and 7%, and the germination rate of the seeds increases, respectively, by 6 and 4. Treatment of seeds rape seeds with the specified concentration increase the germination energy by 9% and seed germination by 5%, while the reference drug increased the germination energy by only 3. Example 7. Dill seeds were soaked in cis-o-8-menten solutions for 12 hours and then sown in Petri dishes with a bed of fil rovalnoy paper. Table 8 presents data on the effect of cis-o-8-mentene on the sowing qualities of dill. Cis-o-8-mento at 0, the concentration increases the germination energy and germination of the fennel seeds.
