В Нижнем и Верхнем дендрологических садах Санкт-Петербургского государственного лесотехнического университета в Санкт-Петербурге выращивается 13 видов и 1 гибрид рода Larix Mill., представленных 124 экземплярами, в возрасте от 25 до 200 лет. Все зимостойки, образуют шишки, 3 вида (L. archangelica, L. decidua, L. sibirica) дают самосев. Всего за период интродукции были испытаны 23 таксона рода Larix, наибольшее число видов здесь впервые испытал Э.Л. Вольф. Некоторые виды (L. komarovii, L. maritima) здесь были впервые введены культуру. В коллекции сохранились старовозрастные экземпляры, посаженные еще в XIX в. – 71 шт., самые старые посадки (9 деревьев) датируются 1820 г. (L. archangelica, L. decidua, L. sibirica). Самое высокое дерево относится к L. sibirica: 34,0 м выс., самое толстое по диаметру ствола – L. decidua: 102 см. Исследования подтверждают важность периодических биометрических измерений и непрерывного мониторинга коллекции. Отдельные деревья заслуживают внесения в базу данных по деревьям-чемпионам по их размерам в высоту и диаметру ствола. There are 13 species and 1 hybrid of genus Larix Mill., represented by 124 trees, in collection of the Upper and the Lower dendrological gardens of Saint-Petersburg State Forest-Technical University, under the age from 25 till 200 years old. All of them are winter hardy and produce cones. Three species (L. archangelica, L. decidua, L. sibirica) give self-sowing. Totally there are 23 taxa which have been tested for the period of introduction. The largest amount of species were tested by E.L. Wolf. Some species (L. komarovii, L. maritima) were introduced here into general cultivation. There are trees of old age planted as early as in the XIX century (71). There are 9 of oldest trees cultivating since 1820 (L. archangelica, L. decidua, L. sibirica). The tallest tree is of L. sibirica: 34,0 m high, the most thick on trunk diameter is the tree of L. decidua: 102 см. The research confirm the importance of periodical biometrical measurements and uninterrupted monitoring of all collection. There are certain trees which deserve to be included into the data base on Champion trees on their sizes.

История коллекции тропических и субтропических растений Ботанического сада СПбГЛТУ насчитывает 175 лет с 1834 г., когда на территории СанктПетербургского Форст института была построена первая оранжерея. На протяжении почти двух веков коллекция формировалась и использовалась для обеспечения учебного процесса. В XIX начале XX вв. каталогизация коллекционных фондов проводилась по системе А. Энглера, начиная с 80х годов прошлого века по системе А.Л. Тахтаджяна. В работе представлен обзор коллекции тропических и субтропических растений на основе современных международных классификаций: APG IV, PPG I и т. д., основанных на молекулярных исследованиях и насчитывает 1344 таксона из которых 996 видов, 65 разновидностей и 283 культивара. Все растения относятся к классу Equisetopsida C.Agardh, и входят в состав 7 подклассов, 53 порядков, 124 семейств и 428 родов. Коллекция птеридофитов представлена тремя порядками и включает 14 семейств, 25 родов, 52 вида и 14 культиваров (66 таксонов). Коллекция голосеменных содержит 4 подкласса, 6 порядков, 9 семейств, 17 родов, 24 вида и 5 сортов (29 таксонов). Коллекция покрытосеменных имеет один подкласс Magnoliidae, 10 надпорядков, 41 порядок, 101 семейство, 386 родов, 920 видов, 65 тпр, 264 культивара (1249 таксонов). Международноунифицированный подход к классификации растений является важным шагом в усилении международной стандартизации обучения. The history of the collection of tropical and subtropical plants of the Botanical Garden of St. Petersburg State Forest Technical University is 175 years old. It dates back to 1834, when the first greenhouse was built on the territory of the St. Petersburg Forest Institute. For almost two centuries, the collection was formed and used to support the educationprocess. In XIX and early XX centuries cataloging of collection funds was carried out according to the system of A. Engler, starting from 1980s, according to the system of A.L. Tahtajyan. The paper presents a review of the collection of tropical and subtropical plants based on modern international classifications (APG IV, PPG I, etc.), based on molecular studies. The collection accounts for 1344 taxons of which 996 species, 65 varietiesand 283 cultivars. All plants belong to the class Equisetopsida C.Agardh, and are included in 7 subclasses, 53 orders, 124 families and 428 genera. The pteridophyte collection is represented by three orders and includes 14 families, 25 genera, 52 species and 14 cultivars (66 taxa).The angiosperm collections have one subclass Magnoliidae, 10 superorders, 41 orders, 101 families, 386 genera, 920 species, 65 varieties, 264 cultivars (1249 taxa). This internationally unified approach to the classification of plants is an important step in strengthening the international standardization of training.

The Relationship

Purpose. Life, scientific and pedagogical way of А. М. Krasnov at the time of the formation of geography was unique, versatile, often contradictory, but clearly creative and innovative approach to everything that was within his interests. Despite some hasty results that harmed his general authority, the figure of A. M. Krasnov – the professor of Imperial Kharkiv University, the founder of Batumi Botanical Garden – is still of interest. Attention has veen paid to the period of his initial formation as a scientist, communication with V. I. Vernadsky, comparison of A. M. Krasnov’s works with works of other researchers, the implementation of the idea of plant introduction. Method. Authentic scientific works of A. M. Krasnov and his contemporaries have been used in the work. Through the use of historical and historiographical sources and comparative analysis there have been revealed those inconsistencies in his works which caused sharp criticism of reviewers. Results. Studies of the work of the first domestic doctor of geographical sciences Andriy Mykolayovych Krasnov have showed his passion for expeditionary research, charisma, thirst for knowledge, love of nature, rich innovative heritage. Attention has been paid to the initial stage of his life, when the interest in scientific, in particular, expeditionary research, which did not leave him during his life, emerged. Based on the study of the relationship between A. M. Krasnov and V. I. Vernadsky, a conclusion about his extraordinary character, ingrained sense of independence, but also passion, excessive emotionality, haste of conclusions has been made. The authors have given the generalized description of the state of the study of geography, which was considered an auxiliary science in the universities of the Russian Empire in the late XIX century, because for A. M. Krasnov it became a source of innovation. The article reveals the extraordinary scientific courage of A. M. Krasnov, who in his doctoral thesis considered the views of famous scientists on the causes of steppe plains. The analysis of А. М. Krasnov’s publications and other sources has proved that he became the creator of constructive geography, combined theoretical classes with practical ones in nature, initiated student scientific expeditions, founded a student geographical society and a geographical office. Possessing artistic and literary talent, he became one of the best promoters of exotic regions, visiting dozens of countries around the world. The authors have also traced the reasons why his scientific works were treated with skepticism and distrust. Scientific novelty and practical significance. Some details of the relationship between A. M. Krasnov and V. I. Vernadsky have been clarified. The reasons that led to the ignoring of the scientific achievement of A. M. Krasnov by contemporaries have been revealed. It is expedient to use these materials while writing the full scientific and pedagogical biography of professor A. M. Krasnov.

The Impact

The paper investigates the impact of some features of the 90s in Germany: shareholder-value orientation and changes in the distribution of share capital, booming asset prices, profit-sharing schemes including option plans, increased capital funded old-age provisions. Two propositions are discussed and, finally, denied: Due to these trends there might emerge a tendency towards a more equal distribution of capital stocks, and a relevant portion of employees might turn out as shareholders with considerable non-wage income. However, despite severe shortcomings in the data base a wave of further wealth concentration can be observed, and the workers´ share in capital assets has remained insignificant, apart from a small but increasing stratum of middle and high income employees.
