Анализ взаимосвязей линейного роста осевых ауксибластов ветвей и ствола у потомства плюсовых деревьев сосны обыкновенной (Pinus sylvestris L.)

Abstract

The relationship between the characteristics of linear growth of of branches and stem and the possibility of discrimination on its basis of Scots pine (Pinus sylvestris L.) different genotypes were investigated. The subjects of the study were the seed offspring of plus trees at the age of 10 and 11 years. The annual increments of the stem and branches of different exposures were measured. Correlation, regression and developed by authors new methods of data analysis were used. The age dynamics of changes in the values of the trait were taken into account by comparing the coefficients, characterizing the slope of regression straight lines approximating the interconnection of axial increments in two adjacent years, as well as for the entire studied period of development. The results of the studies indicate the greatest relationships between linear growth of auxiblasts in two adjacent years and the difference between the patterns of branch and stem morphogenesis. The possibility of genotypes discrimination based on the characteristics of individual morphogenesis was established.
