[On the similarity in the effects of different cryopreservation conditions on the growth and development of plants].

The morphological characteristics of 35 wild plant species were studied after freezing of seeds under the conditions of deep, fast, and programmed freezing (-196 degrees C) and non-deep freezing (-10 degrees C). The seeds were stored frozen for a month. The seeds of all the species were characterized by a low humidity. The field and laboratory seed germination capacity, leaf growth, the quantity and length of shoots, the quantity of generative organs, and the variability of these characteristics were studied. It was shown that the direction of changes under different cooling conditions was the same except for the laboratory germination capacity of some species. The direction was determined by the species features rather than cooling conditions.
