Influence of winter storage methods of acorns on the development and growth processes of common oak

The economic value and biological stability of common oak stands (Quercus robur L.), grown from acorns is substantially higher in comparison with plantings undergrowth origin. Therefore, the cultivation acorn relevant promising, especially where there no natural restoration oak. purpose study was improvement seed production technology high-quality planting material seeds various methods winter storage to expand area forests. In course study, forest-cultural (determination quality indicators acorns, material, forest cultures), biometric growth mass material), classical statistical research were used. conducted on territory fund Hertsaevsky state special Forestry Kuzmynsky branches “Chernivtsi Forestry” specialised enterprise “Forests Ukraine”. It shown that each storing has its own advantages disadvantages, which are more or less manifested different cultivation. As a result comparing influence development plants stored trench method, it determined best parameters aboveground part observed when using larding method. However, least intensive root system growing closed system. found weighted average processes tap water highest by larding. proved experimental cellar sand lagged behind landing established developed worse an open proposed can be applied improve efficiency reproduction forestry enterprises Ukraine
