Investigation of American cranberry acclimatization at Kaunas Botanical garden of VMU

VDU Kauno botanikos sode atlikti stambiauogės spanguolės Vaccinium macrocarpon Aiton veislių ir klonų augimo bei vystymosi ypatybių Lietuvos klimato sąlygomis tyrimai. Nustatyta, kad stambiauogė spanguolė pradeda žydėti birželio antroje dekadoje, todėl uogų derliaus dydį gali sumažinti tik labai stiprios pavasario šalnos pačioje ūglių augimo pradžioje. Pagal masinio nikimo datą stambiauogės spanguolės veislės ir klonai suskirstyti į tris grupes: ansktyvąsias (“Bergman”, “Ben Lear”, “Black Veil”, BL-8, “Washington”, “Early Black, BL-10, BL-6), vidutinio ankstyvumo (“Stevens”, “Howes”, “Prolific”, “Holliston”, “Woolman”, “Le Munyon”, “BL –15, BL- 22, NSV-108, “Crowley”) ir vėlyvąsias (“Matthews”, “Mc Farlin”, “Wilcox”, “Drever”, “Howard Bell”, “Bain MC).[...]Evaluation of American cranberry Vaccinium macrocarpon Aiton cultivars and clones was accomplished at Kaunas Botanical Garden of VMU. The seasonal growth and development was estimated under Lithuanian climate conditions. The flowering period of American cranberry starts at the second decade of July, therefore, only early spring frosts can damage shoots apexes. Three clusters in accordance with mass ripening date were selected:early (“Bergman”, “Ben Lear”, “Black Veil”, BL-8, “Washington”, “Early Black, BL-10, and BL-6), mid - season (“Stevens”, “Howes”, “Prolific”, “Holliston”, “Woolman”, “Le Munyon”, “BL–15, BL-22, NSV-108, and “Crowley”) and late cultivars and clones (“Matthews”, “Mc Farlin”, “Wilcox”, “Drever”, “Howard Bell”, “Bain MC).[...]Botanikos sodasVytauto Didžiojo universiteta
