Abstract

The paper presents the relationship between root formation and post-regeneration development of root systems and the overground part of annual cuttings of Norway spruce. Rooting was carried out in substrates with different water and physical properties (perlite, vermiculite, river sand). The variability of the analyzed characteristics is established, which is referred to the low and medium level of the Mamaev scale with respect to the linear parameters of cuttings. Varying the callusogenesis values corresponds to a very high level of the same scale. The variability of characteristics stipulates the need and expediency of determining the nature of the relationship between their variations. The correlation and regression analysis performed according to traditional methodological schemes is chosen as the form of the study. The correlation between the indices of regenerative processes occurring during the rooting of cuttings and their further development is established. Quantitative evaluations of Pearson pair correlation coefficients allows expressing the correlation ratio in the qualitative categories of the Chaddock scale. The relationship between the linear parameters of cuttings is defined as a positive strong one. A reliable positive correlation, assessed as moderate, is observed between the intensity of callusogenesis and the percentage of rooted cuttings. The dependence of changes in one index of the regenerative capacity of cuttings on the nature of variation of another one is adequately described by the equation of a straight line. The height of the aerial part of the rooted cuttings is associated with their diameter (R² = 0.521), and depends little on the values of the other analyzed characteristics (R² < 0.055). The rooting ability of cuttings is related to the total current increment of shoots in length (R² = 0.378). The intensity of callus formation is very indifferent to other characteristics under consideration.
