Ujedno je ispitivano stanje neproređivanih sastojina po istim karakteristikama. lstraživanja su izvršena na području Raške u sastojinama starosti 30-50 godina. The effect of thinning performed at different times on crown structure, diameter increment, quality, health condition and production characteristics was researched in artificially established Austrian pine stands. The same characteristics were simultaneously researched in unthinned stands. The research was performed in the region of Ra5ka in the stands aged 30-50 years.
