STUDY ON THE PRODUCTION OF GRAFTED VINE CUTTINGS USING TWO PLANTING VARIANTS IN THE VINE SCHOOL AND THEIR EFFICIENCY

Dry grafting on the table is the most used method for vegetative propagation of vines. During the period 2021-2023, 48,000 vines of the Fetească Regală 21 Bl variety were grafted at the Murfatlar Research Station. After grafting, the cuttings were paraffined, stratified, then forced. After forcing, the vines were acclimatized and prepared for planting in the vine school. The percentage of the grafted vines resulting from forcing and good for planting was between 90-95 %. Half of the grafted vines were planted on soil ridge covered with black mulch foil, and half planted on the soil ridge but uncovered. Thus, the yield of the vines and the economic efficiency of each variant could be observed. The grafted cuttings were harvested from the vine school in November, and the yield was 35.66%for the variant planted on the soil ridge covered with mulch foil and 34.33% for the variant planted uncovered. The difference is insignificant and we can say that the planting method did not influence the yield of the grafted vines.
