The right and left forms of spruce progenies of plus trees in the Perm region

It was found that the progeny of plus-trees from natural stands dominated by leftists (love of light-tions), and progeny from plantations - right (shade-tolerant) form. First and second offspring of populations, with the division into groups with positive and negative-term response to the increasing density of cultivation, have a different relationship between these different forms and the evolutionary response to changes in density of growth in test cultures, aligning the proportion of left and right forms.
