Abstract
A comparative study of the effect of different storage regimes of seeds (at + 5 ° С, -20 ° С and under deep freezing conditions at -196 ° С) of two cultivated plants of the Abutilon theophrasti Medik. and Eruca vesicaria (L.) Cav. on their viability and the development of plants from them in the field was carried out. Freezing increases the laboratory and field germination of the seeds of the A. theophrasti and does not significantly affect the germination of the seeds of the A. theophrasti, and also increases the germination energy of the seeds of both plant species. It did not cause the appearance of non-viable, ugly seedlings and plants. Plants went through a full development cycle and set full-value seeds. Biometric parameters of plants obtained from thawed seeds and control ones are very close. Cryopreservation is a promising way of storing seeds of the studied species, since it ensures longer periods of preservation of their viability. Keywords: ABUTILON THEOPHRASTI; ERUCA VESICARIA; SEED BANKS; LONG-TERM SEED STORAGE REGIMES; CRYOPRESERVATION
