New finds of wild grapes of the Kuban region and their environmental and geographic characteristics

Abstract

This article presents the study results of new locations of wild forms of the Krasnodar Territory, Crimean region. Two populations in two locations were found in the slope and plain territories. In the course of the expeditions, the environmental and geographic characteristics of the habitats of wild grape forms were given, a complete description of the vegetation of the ecotopes under study was made, and the morphological and biological qualitative and quantitative indicators of grape wild forms have been studied in detail. When analyzing scientific literature data, it was found that there is not enough information about Kuban wild plants, feral forms and autochthons of grapes. The urgent need for this study arose. The research was carried out using route-reconnaissance, geobotanical, ampelographic, analytical methods. The variability of some indicators was detected to a greater or lesser extent, both at interpopulation and endogenous levels. Populations differ in the shape of the leaf blade, with leaves occurring pentagonal, deltoid, and rounded. The degree of leaf corrugation varies from weak to medium. The crown of the young shoot is slightly open or half open, with very rare pubescence, the depth of the upper lateral leaf clippings is from very small to medium.
