THE CREATION OF BIOTECHNOLOGICAL PLANT COLLECTIONS IN THE BOTANICAL GARDENS OF RUSSIA AS ONE OF THE PROMISING DIRECTIONS FOR THE CONSERVATION OF THE BIOLOGICAL DIVERSITY OF LIVING SYSTEMS | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 The wood-destroying fungus Laetiporus sulphureus (Bull.) Murrill from the pathogenic Polyporaceae population growing on oak Quercus robur L. was the focus of study. It is considered to have nutritional and medicinal value for the immature fruiting bodies of Laetiporus sulphureus living on deciduous trees. The development of an algorithm for assessing the yield and stock of Laetiporus sulphureus is the subject of study. In the Coppice oak forests of the southwest of the Central Russian Upland, experimental studies were performed in 2010-2018. The studies in the oak forests of the southwest of the Central Russian Upland were performed in 2010-2018 and a field survey is being carried out. The prevailing models of Laetiporus sulphureus on various types of oak substrates are proposed as a result of statistical processing of the obtained experimental material. The models served as the basis for an evaluation algorithm for Laetiporus sulphureus yield and stock. To recalculate the number of oak trees and tree units of oak (dead wood, windbreak, stumps) with fruit bodies of L, the researchers estimate the area occupied by 100 oak trees in the stand and equate it with an area of 1 ha. Sulphureus (the number of L. sulphureus fruit bodies) per hectare in the first half of the year.
