Microelements needles in progeny of the culture and natural populations Finnish spruce

The analysis of the content of 10 microelements (ME) in the needles of 107 trees in a 26-year-old cultures in loamy soils in the progeny of natural populations (N) and cultures (C). Variation ME averaged in the progeny N and C, respectively, 48% and 45.4%, and the majority of the series is significantly different from the normal distribution of the Gauss-Laplace. Found that offspring whose parents have more signs of european spruce, less accumulates ME has a lower ash content of needles and reduces it whereas soil increases their concentration (r = -0.38 ± 0.13). Needles of offspring N whose parents are more signs of Siberian spruce, on the contrary, gained ME the more, the more ash increased soil (r = 0,29 ± 0,14).
