Досліджено якісні показники фітомаси компонентів стовбура (локальну та середню природну й базисну щільності деревини, деревини в корі та кори) штучних насаджень сосни звичайної (Pinus sylvestris L.) різних режимів вирощування в лівобережній частині Північного Степу. Виявлено, що проведення рубок догляду сильної інтенсивності незначно вплинуло на показники локальної базисної щільності деревини: різниця між ними для густих і менш густих насаджень у межах одного екотопу на всіх відносних висотах є несуттєвою. Водночас суттєво більшим є показник середньої базисної щільності деревини в сухому бору, порівнюючи зі свіжим субором: у густих насадженнях – на 18,4 %, у менш густих – на 8,2 %. У степових посушливих кліматичних умовах України в сухому бору та свіжому субору в штучних насадженнях сосни не виявлено суттєвого впливу інтенсивності рубок догляду на якість деревини сосни.
