Flow hydroponics as a solution to the problem of adaptation of microplants of rosette crops

With rosette microplants of garden strawberry (Florence cultivar), pineapple (Smooth Cayenne cultivar) and sugar beet (BV2 form), an attempt was made to transplant them into flow-through hydroponics to carry out adaptation to non-sterile conditions. Plants cultured on Murashige-Skoog nutrient medium at 23±1°C, 16-hour photoperiod and illumination of 5-6 klk were used in the experiment. Flow-through hydroponics was used for adaptation of the microplants. Plastic boxes measuring 0.6 x 0.4 m x 0.04 m (volume 9 l) were used for the hydroponic system. Plastic frames covered with non-woven polymer material (Lutrasil, 17 g/m2) were installed on top of them. The surface of the material was perforated with holes of 3-4 mm in diameter with a planting pattern of 3.5 × 3.5 cm (150 pcs./box), into which plants were planted. The survival rate of plants for 1 month was 100% for all crops.
