AŁYCZY SEEDS. They are commonly used in the production of plum trees, peaches and apricots. All trees are judicious, resistant to frost, in snowless winters, however, their root system may freeze. Alech seedlings grow well in the nursery and are therefore highly valued by nurserymen, however, fusion of these rootstocks with some varieties of plums is very slow. Quite often many maimers are broken during stronger winds. Alech seedlings also grow badly with some varieties of peach and apricot. A large number of maimers show symptoms of incompatibility.
Plum trees, peaches and apricots grafted on alech are undemanding to the soil.
Under the conditions of good care, even on lighter soils, they grow strongly and by the third year they begin to bear fruit.
Hungarian Wangenheima seedlings. Recently, they have been recommended for the production of plum trees. The results obtained from the experience so far indicate very good fruiting of Hungarian Italian trees on this rootstock. Hungarian Wangenheim trees are commonly grown in production orchards. This allows you to easily obtain the necessary amount of seeds. The seeds of this Hungarian woman in field conditions (after stratification) they usually sprout less than the seeds of alchemia. Growth of young seedlings is also slow. For these reasons, it has so far been rarely used for the production of plum trees.
BROMPTON PLUM. It is a vegetative rootstock selected in England from the group of domestic plum trees. In Western European countries it is quite commonly used for the production of peach and apricot trees. It reproduces difficult by horizontal dumps and is classified as inefficient. The Brompton rootstock can also be propagated by green cuttings. The frost resistance of Brompton plums is similar to that of plums. In Poland, the Brompton rootstock is recommended primarily for the production of Hungarian Italian trees. The plum trees on this rootstock grow strongly in the first years. They bear fruit in the third or fourth year after planting and bear fruit very abundantly. For these reasons, the share of Brompton rootstocks in the production of plum trees should increase rapidly in the coming years. A serious difficulty in increasing the production of Brompton rootstocks is their high susceptibility to infection by the most serious viral disease of plums – sharka.
For peach rootstocks, apart from alech seedlings and Brompton rootstocks, peach seedlings resistant to frost are recommended, and for apricots – apricot seedlings from the seeds of frost-resistant trees.
