- Abstract
- Strawberry is one of the most economically significant crops in the world berry growing. In the course of research, the influence of the mineral composition of nutrient media on the growth and development of strawberry plants at the stage of micro-propagation proper was studied for further optimization of the technology of microclonal reproduction. The purpose of the work is to select the optimal nutrient medium for micropropagation of strawberry in vitro in the production system of healthy planting material. The research was carried out in the laboratory of biotechnology of the Russian research Institute of Fruit Grop Breeding according to generally accepted methods. The objects were important commercial varieties of garden strawberries (Fragaria × ananassa Duch.) of foreign breeding: Alba (NF 311), Darselect, Kimberly, Clery, Syria (NF 137), Florence. Variants of the nutrient media formulations used: Lee and de Fossard, Gamborg and Eveleigh (B5), Knop, Murashige-Skoog with the addition of 0.8 mg/ l cytokinin 6-BAP. Optimal recipes of the nutrient medium that promote intensive proliferation and root formation in plants have been determined. For the cultivation of the studied strawberry varieties at the stage of actual micro-propagation with a high degree of regeneration, the optimal nutrient medium is the MS medium. On the nutrient Knop’s medium, the micro-plants on the second passage acquired a reddish color, not characteristic of the studied varieties. The maximum values of plant height were noted in the control variant with MS nutrient medium in the varieties Darselect (9.1 mm) and Kimberly (8.6 mm). In all other variants of the studied nutrient media, the average height of plants did not exceed 7.7 mm. Media according to the LF and B5 recipe can be used to obtain microplants suitable for planting in ex vitro conditions, excluding the rooting stage, to accelerate the production of healthy planting material. A different reaction of strawberry varieties to the mineral composition of nutrient media has been established.
