Abstract

The investigated growth processes of pedunculata oak sapling (Quercus robur L.) received the ambassador consanguine.
It is shown, that in posterity growth sapling is shown to be miscellaneous. With some people to be sapling results in
„inbreeding depressions”, the growth of sapling in diameter is suppressed. This phenomenon speaks of accumulation of
harmful recesivitate factors in posterity. At others sapling heterozygosis is shown. On can see, after crossing a parent tree
with genetically different trees recesivitate genes of one plant ,,are blocked” by dominant genes of another that does not
reduce the sapling growth.
