The article provides a comprehensive assessment of the dendro-introducer Forsythia europaea Vahl state on the territory of the Arkhangelsk agglomeration. The assortment selection in the northern cities remains relevant. Of scientific interest is the landscaping of both territories of limited use and special purposes, as well as public places such as parks, squares, boulevards, landscaping of streets. Between 2002 and 2023 an inventory of plantings in the city of Arkhangelsk was carried out, as a result of which the species Forsythia europaea Vahl, which is unusual for this climatic region, was identified. The article provides a comprehensive assessment of the Forsythia Europea on the territory of the Arkhangelsk agglomeration. The purpose of this work is to study the unique dendro-introducer Forsythia europaea Vahl growing in Arkhangelsk. As a result, data were obtained regarding the characteristics of its life activity such as winter hardiness, frost resistance, sanitary condition, decorativeness, seasonal development and growth. It was revealed that the non-district shrub goes through all the phenological phases characteristic of this species. The annual growth is 0,27 ± 0,050 m, shoot growth continues from June to August. The bush's preparedness for winter is satisfactory — by the beginning of September the shoots become lignified, the green color of the leaves remains until the leaves fall (late October). Flowering continues for more than 10 days until the leaves bloom. Fruiting is less intense than flowering, which is a common feature during the introduction of woody plants to the North. Flowering continues for more than 10 days before the leaves bloom. Fruiting is inferior in intensity to flowering, which is a common feature when introduced to the North. For the studied introduced species, an integral assessment for introduction and calculation of the acclimatization number were carried out according to generally accepted methods. Taking into account the recommendations on the zoning of rocks, we believe that the study of the dendro-introducer Forsythia europaea Vahl, which is unique for the landscaping of the city of Arkhangelsk, should be continued.
Приведены результаты инвентаризации насаждений г. Архангельска в период с 2002 по 2024 гг., в результате которой зафиксирован необычный для данной климатической области вид — Forsythia europaea Vahl. Проанализирована комплексная оценка состояния дендроинтродуцента. Представлены данные об особенностях его зимостойкости, морозоустойчивости, санитарного состояния, декоративности, сезонного развития и роста. Выявлено прохождение всех фенологических фаз, характерных для данного вида. Установлено, что ежегодный прирост составляет 0,27 ± 0,050 м, рост побегов продолжается с июня по август. Определено, что подготовленность кустарника к зиме удовлетворительная — к началу сентября побеги одревесневают, сохраняется зеленая окраска листьев вплоть до листопада (конец октября). Показано, что цветение продолжается более 10 дней до распускания листьев, плодоношение по интенсивности значительно. Проведена интегральная оценка перспективности интродукции и расчет акклиматизационного числа согласно общепринятым методикам. Считаем необходимым продолжить исследование уникального для озеленения г. Архангельска дендроинтродуцента Forsythia europaea Vahl в части выяснения возможных путей его размножения в культуре.
