Rooting capacity of grape cuttings in the north-western caspian region

Abstract

Experience in studying the rootability of grape cuttings was conducted on the territory of the vineyard of the Precaspian agrarian federal scientific center of the Russian academy of sciences, located in the Chernoyarsky district of the Astrakhan region. The research period is from 2015 to 2019. The relevance of the research is due to the insufficient availability of local planting material in the regions of the Russian Federation, as well as the high efficiency of the method for obtaining grape seedlings on their own roots. The purpose of the research was to study the survival rate of grape cuttings in the crop and identify varieties that are characterized by the best rooting ability. The article presents data on the ability to root cuttings of grapes of 18 table varieties of different maturation periods. The lowest rooting rate in the experiment had varieties Cardinal, Straseni, Memory Negros, the Gift to Zaporozhye, Karaburnu. It was found that the use of early – maturing varieties Kodryanka, Bogatyrsky, Lora, middle – matured-Husain pink and Lowland, late-matured-Moscow, Sevan, Soviet, the level of rootability of which varied from 44.2 to 71.4 %, is optimal for obtaining root-related seedlings of grapes.These varieties have a good ability to rhizogenesis, which allows us to recommend them for accelerated propagation of grape varieties.
