The peculiarities of shoots structure in seedlings of population forms and cultivars of Prunus armeniaca L. are considered in the article. The genetic and ecological aspects of shoots structure formation in 615 seedlings of 29 samples of three eco-geographical groups, depending on their origin have been studied. It was found that the one-year old seedlings of apricots had three types of shoots: skeletal (crown-forming), overgrowing and spurs (thorns). The studies conducted on apricot seedlings showed that the structure of seedlings shoot is determined by the degree of cultivation rather than by ecological and geographical division. It is pointed out that the observed similarities between cultivated and wild samples from Dagestan are associated with the existence of multitude transitions from the cultivated to wild types, and, perhaps, this is indicative of their mutual penetration in the areas of wildness and domestication.
В статье рассмотрены особенности структуры побегообразования сеянцев популяционных форм и культиваров Prunus armeniaca L. Исследованы генетические и экологические аспекты формирования структуры побегов у 615 сеянцев 29 образцов из трёх эколого-географических групп в зависимости от их происхождения. Для однолетних сеянцев абрикоса выявлено три типа побегов: скелетные (кронообразующие), обрастающие и шпорцы (колючки). Проведённое исследование по сеянцам абрикоса показало, что структура побегообразования сеянцев определяется степенью окультуренности, а не эколого-географическим разделением. Выявленное сильное сходство между культурными и дикорастущими образцами из Дагестана связано с наличием множества переходов от культурного типа до дикого и, возможно, говорит об их взаимных проникновениях в зонах одичания и одомашнивания.
