Date of «birth» of phytosociology (phytocenology) is considered to be 1910, when at the third International Botanical Congress in Brussels adopted the definition of plant association in the wording Including Flaó and K. Schröter (Flahault, Schröter, 1910; Alexandrov, 1969). The centenary of this momentous event in the history of phytocenology devoted to the 46th edition of the Yearbook «Braun-Blanquetia», which began to emerge in 1984 in Camerino (Italy) and it has a task to publish large geobotanical works. During the years of the publication of the Yearbook on its pages were published twice work of the Russian scientists — «The steppes of Mongolia» (Z. V. Karamysheva, V. N. Khramtsov. Vol. 17. 1995), and «Classification of continental hemiboreal forests of Northern Asia» (N. B. Ermakov in collaboration with English colleagues and J. Dring, J. Rodwell. Vol. 28. 2000).

This paper is concerned with vegetative reproduction, which is the only mode of propagation in cultivated grapevines. After a brief summary of the systematics of the Vitaceae the question of the nomenclature of cultivated grapevines is discussed. Intra-varietal variability is discussed using morphological and molecular characteristics. The origins of variation are presented: mutations, foreign nucleic acids, and memory of previous environmental conditions. Grapevines provide characteristic products, leading viticulturalists to make selections among the diversity observed in the vineyard, thus decreasing diversity. Grapevines interact with various environmental agents. One example, the natural defence provided by resveratrol, is analysed, showing its direct effects against parasitic fungi and its indirect effects, both metabolic and genetic, on other organisms. Thus, the grapevine, viticulturalists, and their environment form a web of biological interactions.

At the 1999 International Botanical Congress held in St Louis, Missouri, the President of the Congress, Dr Peter Raven, presented a keynote address emphasizing the importance of plants to human existence and underlined concerns that the Earth is undergoing a human-induced extinction crisis. One of the resolutions of the congress was to establish a new co-ordinating body associated with the United Nations to monitor the status of plants throughout the world and take steps to conserve them. The resolutions were followed up with a meeting in Gran Canaria on 3–4 April, 2000 when leading botanists met to formulate a declaration which could be taken forward to the fifth Conference of the Parties (CoP5) to the Convention on Biological Diversity held in Nairobi in May 2000. CoP5 recognized that plant diversity is a common concern of humankind and an essential resource for the planet, with as many as two-thirds of the world's plant species in danger of extinction, and proposed that at the sixth meeting of the Conference of the Parties (CoP6) the establishment of a global strategy for plant conservation should be considered. A strategy with 16 targets was presented and adopted at the CoP6 meeting held in The Hague in April 2002. These targets differ from the normal approach adopted in the Convention on Biological Diversity of using general principles that can be interpreted by national policy, in that they are quantified.
