Determination of Average Annual Increments Based on the Mean Diameter of the Horizontal Crown Projection and Bole Height of Forms of the Walnut (Juglans regia L.) Collection Under the Conditions of the Main Botanical Garden of Almaty for the Period 2013–2022 and the Relationships Between Them

The results of introduction studies on the biometric parameters of walnut (Juglans regia L.) forms under the conditions of the Main Botanical Garden of Almaty are presented. Based on statistical modeling, a comparative analysis of long-term age-related changes was carried out. Independent variables were obtained in the form of minimum, maximum, and mean collection values of tree height, trunk diameter, horizontal crown projection diameter, and bole height of tree forms. The confidence interval and standard deviation were determined, and the relationships between the studied parameters were assessed through regression equations and correlation coefficients.
