Analysis of the Dynamics of Ontogenesis of Birch Leaves (Betula Pendula) Under Environmentally Friendly Conditions

The method of rank distribution of five parameters (ontogenesis period, length, width, perimeter, area) of 20 accounting birch leaves in the dynamics of ontogenesis by 12 measurement dates is presented. Without modeling by ranks, the quality factor of measurements is revealed. By the sum of the ranks, leaflets No. 19 and No. 20 turned out to be the best. They are on the western side of a young birch. By rank, research can also be carried out in schools. Further, factor analysis is carried out in four stages: identification of patterns of rank distribution; rating of rows and columns of the data matrix; identification of patterns and rating of binary relations by the correlation coefficient. By reducing the correlation of the equations of rank distributions, the parameters are located: 1) 1.0000 - the growing season; 2) 0.9999 - the length of the birch record sheet; 3) 0.9999 - width; 4) 0.9941 - perimeter; 5) 0.9890 - area. The rating by rows and columns showed that the vegetation period was in the first place as an indicator. According to the rating, among the influencing variables, the angle of the junction of the branch to the birch trunk was in the first place, the length was in the second, and the width was in the third. As a dependent indicator, the length is in the first place, the width is in the second, and the area is in the third. With waves ranked as influencing variables, length was number one, width was number two, and area was number three. Taking into account wavelets, the angle of junction of the branch to the trunk was only in fourth place. As an indicator, the length is again in the first place, the width is in the second, and the area is in the third place. The coefficient of correlative variation of factor analysis, taking into account wave components, is 0.7365. This is a high indicator of the functional connectivity of the “leaves - branches - trunk - soil” system located in ecologically clean conditions. Of the 40 resgularities, 18 equations (45%) were selected, having a closeness of connection of more than 0.7 with a maximum of growth and development during the growing season according to five biological parameters. The maximum correlation coefficient of 0.9994 is observed for the direct and inverse width-length functions. The influence of length and width on other parameters is characterized by a power function. Above a strong level of adequacy of at least 0.9, 13 (32.5%) equations remained. It is proved that only the width can be used in further experiments.
