Effect of competition on resprouting and sprout growth of temperate trees

Patra, Lukáš

Presented thesis is focused on competition, sprout growth and resprouting ability of temperate trees. The main aim was to analyse the effect of competition on resprouting success and sprout growth of selected trees. Calculations are based on sprout size measurements of selected resprouting trees on pre-existing TARMAG II experimental plot near Soběšice, the Czech Republic. Appropriate allometric equations were used to determine biomass of individual trees and pre- and post-harvest competition indices. Statistical analysis disclosed that pre-harvest and post-harvest competition can significantly affect sprout growth of temperate trees, but can differ among species and has variable effect onto the growth. Results also clearly showed that pre-harvest competition did not affect resprouting ability of Quercu spetraea. The results indicate that thinning of sprouts in the early stage of coppice development could support sprout growth and thus biomass production.
