Effect of freezing seeds of kenaf (Hibiscus cannabinus L.) on germination, growth and development of plants

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 a valuable bast fiber culture - kenaf - Hibiscus cannabinus L. on their viability and the development of plants from them in field conditions. Freezing increases the laboratory and field germination of kenaf seeds, and also increases the energy of their germination. It did not cause the appearance of non-viable, ugly seedlings and plants, as well as their death. Plants went through a full development cycle and set full-fledged 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.
