Аннотация: Seed productivity of the macrostrobile and seed quality in drying and healthy stands of the Abies slbirica growing in the mountains of the Southern Siberia - Khamar-Daban and Western and Eastern Sayany - were studied. It was established that under any growing conditions of fir, the seed productivity of its macrostrobile is very high, but the quality of the seeds produced is very low. In high mountains, where an intensive drying of fir forests takes place, seed sterilization increases. Most of the sterile seeds are hollow, which is connected with the low pollen quality. It is concluded that in Abies sibirica growing in the mountains of Southern Siberia, the reproductive potential of the species drops. It is assumed that formation of sterile seeds in a fir may cause the lack of forest-forming processes in fir forests. В© 1996 MAHK Hayka/Interperiodica Publishing.

Аннотация: The methods of sterilization of annual shoots Pinus sibirica Du Tour and the conditions for their introduction into in vitro culture were studied. Induction of callusogenesis of aseptically viable explants of P. sibirica proceeds more intensively on the modified Murasige-Skoog medium: hormonal supply of 0.4% kinetin and 0.25% 6-benzylaminopurine; reduced sucrose concentration of 1.5%. The frequency of callus formation was 83%. Close quantitative indicators of extractive substances were established (36 and 33% of absolutely dry weight for callus and explant, respectively); easily hydrolyzable polysaccharides (18 and 16%) and proteins (11 and 10%).Callus P. sibirica has a higher content of ascorbic acid, flavanoids, tocopherols and ash elements compared to explants and a low amount of hard-hydrolyzable polysaccharides, lipids, tannins, pigments, and essential oils.The electrophoretic spectrum of water-soluble callus proteins is represented by eleven fractions: 63% of the total water-soluble proteins are fractions with a molecular weight of 33 kD and above. Fractions with molecular weights of 50 and 62 kD (20 and 17%, respectively) are represented as much as possible.In the explants of P. sibirica, low molecular weight fractions of proteins with molecular masses of 5 kD and lower (59%) predominate. The amino acid composition of calli and explants of P. sibirica is identical and is represented by fifteen individual amino acids. Callus tissue has a higher content of glutamic acid and two hydrophobic amino acids (proline and isoleucine) compared to the vegetative part of the plant and low tyrosine content. © 2020 Altai State University.
