An agrobiological and techno-logical study of the Pamid grape variety was carried out during the realization of different variants of loading with winter eyes during pruning. An agrobio-logical and technological study of the Pamid grape variety was carried out during the realiza-tion of different loading variants with winter eyes during pruning. It has been established that the phenophases of development during the vegetation period occur and take place al-most simultaneously in the same time periods, and the grapes ripen during the first ten days of September. With the increase in the number of knots of a vine and with their lengthening, there is a well-defined tendency of reducing the percentage of developed winter eyes, fruit-ing shoots, weight per 1 cluster, less of reduc-ing the fertility rate. The vines grow well under the pruning loads of the four variants and the grapes manage to ripen. The best combination of sugar and titratable acid content for wine production is in the grapes from the variants with a load of 6 and 7 knots of a vine. The number of knots has a proven strong or moder-ate negative effect on the percentage of devel-oped eyes, fruiting shoots, bunches, fertility rate, weight of one cluster and 100 grains, dur-ing both years of the study. The increase in the number of knots is in a moderate, positive cor-relation with the yield of one vine.
The possibilities of obtaining an additional grape yield from suckers in early ripening seed table varieties Dunav and Panse Précoce were studied. It was found that, under the soil and climatic conditions of the experiment, the vines of these varieties annually form suckers on their main shoots, from which an additional grape yield can be obtained by the end of the growing season. In the case of Dunav, this yield was 25.30 % and in the case of Panse Précoce − 32.44 % of the yield of the main shoots. In both varieties, there is a mathematically proven very strong positive correlation between most of the studied ampelographic parameters recorded in the main shoots and their suckers. The most frequently observed increase in their values in the main shoots leads to the same in the suckers. The analytical representation of these relationships by regression models proves their direction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
