Cel' issledovaniy – optimizacii regional'nogo sortimenta i podbora sortov zemlyaniki sadovoy dlya vozdelyvaniya po intensivnym tehnologiyam v usloviyah stepnoy zony Samarskoy oblasti. Izucheny fenologicheskie fazy rosta i razvitiya, urozhaynost', sortovye osobennosti nakopleniya himicheskih elementov (kadmiya, svinca, medi, cinka, marganca, zheleza) u perspektivnyh sortov zemlyaniki sadovoy – odnoy iz vostrebovannyh sel'skoho-zyaystvennyh kul'tur regiona. Mikroelementnyy sostav zemlyaniki imeet sortovye razlichiya, poetomu potenci-al'no effektivnym priemom polucheniya ekologicheski bezopasnoy produkcii yavlyaetsya podbor sortov. Issledovaniya provodilis' v techenie 3 let (2011-2013 gg.) v yuzhnoy zone Samarskoy oblasti na promyshlennyh plantaciyah zemlya-niki sadovoy tradicionnyh sortov (korotkogo dnya) Honey, Marmolada, El'santa. Privedeny dannye fenologicheskih nablyudeniy, iz kotoryh sleduet, chto issledovannye sorta v yuzhnoy zone Samarskoy oblasti harakterizuyutsya raznymi srokami razvitiya: sort Honey – ranniy, El'santa – sredniy, Marmolada – ochen' pozdniy. Otmecheno, chto blagodarya pozdnemu sroku cveteniya, sort Marmolada yavlyaetsya bolee vysokourozhaynym (13,0 t/ga), nizhe pokazatel' u sortov El'santa (11,9 t/ga) i Honey (10,9 t/ga). Dlya ocenki ekologicheskoy ustoychivosti v yagodah opredelyali elementnyy sostav tyazhelyh metallov (kadmiy, svinec, med', zhelezo, cink, marganec, zhelezo) metodom atomno-adsorbcionnoy spektroskopii s predvaritel'noy podgotovkoy prob metodom «suhoy» mineralizacii. Vyyavleno, chto ustoychivymi k nakopleniyu toksikantov yavlyayutsya sorta zemlyaniki sadovoy El'santa i Honey, summarnoe nakoplenie tyazhelyh metallov v yagodah etih sortov nizhe, chem v yagodah sorta Marmolada v 2,0 i 1,6 raza sootvetstvenno.
