Description
Summary:The grafted grape culture is highly demanded in industrial production due to a number of advantages in comparison with its own rooted culture. The high cost of production of grafted seedlings and climate change necessitate a change in the planting depth of grape plantations for the Rostov region by reducing the length of the rootstock and the selection of optimal scion-rootstock combinations. In this regard, in 2019-2020, I was on the experimental field of the ARRIV&W – Branch of FRARC, an experiment was laid in order to study the effect of length (from 30 to 45 cm) and varieties (Kober 5BB and Riparia Rupestris 101-14) stock on agro biological indicators of grafted grape seedlings of the Denisovskiy variety. According to the research results, it was found that, depending on the length of the rootstock, with a length of 30 cm, there is an increase in the yield of grafts from the chamber to 82.65%, the survival rate to 82.5% and the final yield of seedlings to 52.4 cm. The greatest influence on the quality of seedlings was rootstock variety. The stock-rootstock combination Denisovskiy × Kober 5 BB has a low seedling yield from 15.5 to 24.6%, which is lower than the Denisovskiy × Riparia Rupestris 101-14 combination with a seedling yield from 36.4 to 52.4%. It can be concluded that, according to the results of the experiment, a positive dependence was revealed in the yield of grafted seedlings of the Denisovskiy variety with a rootstock Riparia Rupestris 101-14 and a rootstock length of 30 cm, in comparison with the widespread rootstock variety Kober 5 BB and a length of 45 cm.
