Varietal reaction of potato plants grown on aeroponic installations

Abstract

The article presents data on study of the productivity of potato early ripening varieties (Legenda, Russia; Red Scarlet, Netherlands) and middle-early varieties (Irbitskiy Russia; Gala, Germany) grown on aeroponic installations in artificial lighting conditions: three-tier adaptive installation (“Syntol” production) and single-tier installation produced by “Biological systems” plant. Potato plants were characterized by active growth and development. Their height ranged from 71.0 to 94.2 cm among the varieties, the number of leaves formed on one plant – from 23 to 31 pieces. The formation of mini-tubers was noted from the 46th day (Legenda variety) to the 53rd day (Irbitskiy variety). The first harvest was obtained at the 65th day in early varieties and at the 67th day for middle-early varieties beginning from planting of micro-plants on to the adaptation installation. The productivity of plants by varieties ranged from 123.0 g (Legenda) to 216.1 (Gala) g of mini-tubers per plant, output of mini tubers from 68.1 (Irbitskiy) to 105.2 (Legenda) pieces per plant, the mass of one mini-tuber ranged from 1.17(Legenda) to 2.73 g (Red Scarlet).
