etiolation

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. As a control, plants grown during the photoperiod day / night 16/8 were used. Some features of the growth and development of Triticum aestivum L. plants were revealed under etiolation conditions. It was established that differences in the length of the root system of etiolated and control seedlings are determined by the length of the roots of the upper tier.

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.
