В связи с климатическими изменениями в Анапо-Таманской зоне Краснодарского края виноград страдает от недостатка осадков и повышенных температур в период активного роста ягод, что влияет на качественные и количественные показатели урожая и винной продукции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Изучались 6 сортов винограда различного эколого-географического происхождения по общепринятым физиолого-биохимическим методикам.</p></sec><sec><title>Результаты</title><p>Результаты. Для сортов ‘Красностоп АЗОС’ и ‘Алиготе’ в период активной вегетации отмечено меньше водопотерь – 12,34–15,54%, в то время как у сортов ‘Кристалл’, ‘Достойный’, ‘Восторг’, ‘Зариф’ этот показатель составлял 16,32–23,82%. Изучение содержания фотосинтетических пигментов показало, что у сортов ‘Красностоп АЗОС’ и ‘Алиготе’ в течение лета отмечена наибольшая доля каротиноидов в пигментном составе листа, обуславливающих устойчивость к засухе. К концу лета у этих сортов отношение «хлорофиллы / каротиноиды» было равно 2,93 и 3,15 соответственно, в то время как у сортов ‘Кристалл’, ‘Достойный’, ‘Восторг’, ‘Зариф’ этот показатель был в пределах 3,25–3,58.</p></sec><sec><title>Заключение</title><p>Заключение. По результатам предварительных исследований сорта ‘Красностоп АЗОС’ и ‘Алиготе’ можно рекомендовать для использования в селекционной работе с целью получения новых засухоустойчивых сортов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Due to climatic changes in the Anapo-Taman zone of Krasnodar Territory, grapevine suffers from a lack of precipitation and elevated temperatures during the active growth of berries, which leads to a deterioration in the quality of grape harvests and wine products.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Six grapevine cultivars of various ecogeographic origin were studied with conventional physiological and biochemical methods.</p></sec><sec><title>Results</title><p>Results. The study of the water regulation in leaves showed that cvs. ‘Krasnostop AZOS’ and ‘Aligote’ manifested lower moisture losses during their growing season in summer: 12.34–15.54%. For cvs. ‘Kristall’, ‘Dostoyny’, ‘Vostorg’ and ‘Zarif’, this indicator varied within 16.32–23.82%. As for the photosynthetic pigment content, ‘Krasnostop AZOS’ and ‘Aligote’ had the largest share of carotenoids in their leaf pigment composition in all phenophases, which determined resistance to drought. By the end of the summer, the chlorophyll/carotenoid ratio in those two cultivars reached minimal values: 2.93 and 3.15, respectively. In the leaves of ‘Kristall’, ‘Dostoyny’, ‘Vostorg’ and ‘Zarif’, this ratio was within 3.25–3.58.</p></sec><sec><title>Conclusion</title><p>Conclusion. Cvs. ‘Krasnostop AZOS’ and ‘Aligote’ can be recommended for breeding practice to develop new cultivars that might inherit physiological features inducing drought resistance.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Vitis vinifera L.</kwd><kwd>оводненность</kwd><kwd>хлорофиллы</kwd><kwd>каротиноиды</kwd><kwd>засуха</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vitis vinifera L.</kwd><kwd>moisture</kwd><kwd>chlorophylls</kwd><kwd>carotenoids</kwd><kwd>drought</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания FGRE-2022-0004 «Разработка и реализация методологии управления биологическим, продукционным и адаптивным потенциалом ампелоценозов по критериям экологической, эдафической и пищевой безопасности, энерго-ресурсосбережения в условиях техногенной интенсификации производства и изменений климата на 2022-2026 гг.».
