SELECTION OF NUTRIENT SOLUTION FOR CLONAL MICRO-PROPAGATION OF INTRODUCED ROSE VARIETIES (ROSA L.) IN THE CONDITIONS OF THE FOREST-STEPPE OF UKRAINE

The article deals with the study on inclusion of biotechnology in selection roses. Roses are heterozygous plants and by seed propagation give splitting. Therefore, to accelerate reproduction new existing starting material, clonal micropropagation was included study. vitro process is influenced various factors. It should be noted that, initial stages it age mother plant season material isolation even from which part explant selected its size. next step pay attention sterilizing agent sterilization exposure period. One main factors influencing micro-propagation genotype, hormonal factor composition nutrient medium. At last stage propagation, role played condition regenerating physical valuable varieties decorativeness permanent flowering capacity as well originators were used research. gives a brief description genotypes Highlighted data optimal largest number formed micro shoots achieved. investigated that when biotechnological unit roses, determined concentration cytokinins, namely BAP 0.5 mg/l 1.0 mg/l. such concentrations, no callus formation observed most cases, indicators their length optimal. In addition, genotype original sample. Thus, our studies, best for produced Tchaikovski Koralovyi Surpryz varieties.
