The object of the study was sprouts of spring soft wheat Triticum aestivum L. Cultivation was carried out in a climatic chamber at a temperature of 18 ± 1°C under the conditions of a sixteen-hour photoperiod and complete etiolation. The experiment was carried out in the following options: removed the main germinal root; decapitation; removed the lower tier of germinal roots. Removing part of the root system of plants cultivated under a sixteen-hour photoperiod increases the root index and reduces the total length of the root system.
