8vo (188 x 128 mm). 51, (1) pp. Illustrated with twelve figures in the text. Original staple-stitched printed wrappers on grey stock. Rare Georgian translation of the 1911 Russian work by A. M. Dement'ev, "Kratkoe rukovodstvo k razvedeniiu vinogradnikov na amerikanskikh podvoiakh na Kavkaze" ("A Short Guide to Cultivating Grapevines on American Rootstocks in the Caucasus"). The present edition was published by the Tbilisi Provincial Committee for Viticulture and Enology (Mevenakheobisa da meghvineobis t'pilisis sagubernio k'omit'et'i). - "Grape phylloxera arrived in Georgia via the Black Sea in the early 1880s wreaking havoc for the first ten years. Word of the troubles across vineyards in Europe arrived just prior to the insect's arrival, and by the time human traffic introduced infected vines, the answer, being grafting with American rootstock, was understood by a few individuals. As the infestation spread, devastating the western region (particularly Imereti), Phylloxera Committees were created and a series of techniques (such as fumigation and pesticides) were used to no avail. It wasn't until the 1890s, when Georgian agronomist Vladimir Staroselsky, informed by colleagues in the sciences, was successful in persuading the government to utilize American grapevines rootstock, which were then being used for grafting in Europe. At this point, due to the restriction on imported vines to control the spread, seeds from American vines were tried and subsequently failed in experimental plots. In 1893, Staroselsky traveled to France and returned with American phylloxera-resistant vines to establish a mother nursery for rootstock, later named the Viticulture Experimental Station in Sakara, in western Georgia. By 1895 additional nurseries were built to distribute rootstocks to growers, who were being trained by 1897 about the insect, grape botany, as well as how to graft and its necessity. Nurseries and education programs developed in the 1890s spread east across the country along with phylloxera until it came under control" (Phren). - We can only trace the copy held by the Georgian Parliamentary National Library. - Rust to staples, else very good. - Aurora Prehn, "Grafting the Grape: The Rich History of Georgian Winemaking", blog of the Missouri Botanical Garden, 11 November 2021.
