Effect of thinning on acorn production of old sprout-origin sessile oaks (Quercus petraea /Matt./ Liebl.)

Original language description

The value of the standards in a coppice-with-standards lies in the production of valuable assortments and in the production of seeds. The seed production of old sprout-origin sessile oaks (Quercus petraea /Matt./ Liebl.) in the second, third and fourth year after a thinning was observed. Basic dendrometric characteristics such as crown volume, crown area, diameter at breast height, tree height and crown base height were determined for 36 sample trees. Seed traps were used to measure seed production. The thinning intensity pertaining to each individual tree was evaluated using a position-based competition index. In the second year after thinning (2010), a weak to medium crop (26 acorns per m2 of crown projection area) was recorded. The total number and weight of acorns per tree were negatively correlated with the thinning intensity. In 2011, a mast year with an average production intensity of 439 acorns per m2, there was no correlation between thinning intensity and total number or weight of acorns per tree. In the third year of observation, no seeds were produced. The total number of acorns per tree was positively correlated with the breast-height diameter of the sample trees during 2010 and 2011. No trade-off was observed between the total number of acorns and the basal area increment during the period of observation. Thinning did not enhance the average total acorn production per tree and it decreased the number of masting trees. This led to a decrease in the total acorn production per hectare.
