The article deals with the results of correlation and regression analysis of the starch content in the tissues of annual shoots of various spruce species under the conditions of introduction into Nizhniy Novgorod region. Estimates of the tightness of the connection between the analyzed indicators are given, and the regression equations are given. The greatest positive correlation was found between the content of starch in phloem and its total quantity. Research objective – to reveal existence and to define narrowness of communication between indicators of content of starch in fabrics of year escapes at different types of a fir-tree. Analyzed even-aged trees with an identical area of food and other equal conditions of growth. In total 145 samples prepared in March, 2016 are tested. Communication between the content of starch on separate fabrics in this regard is significantly less.
