“…In Erzincan, a 25-year-old vineyard at 1190 m altitude in Baran trained system was used. Examples of genotype 'Ülkemiz' belonging to V. labrusca specie, which stands out with its resistance to high humidity and low temperatures [29][30][31]. It was obtained from Samsun Ondokuz Mayıs University.…”

This study was conducted to reveal the relationship between the number of clusters and of primary buds size in dormant grapevine winter buds. In addition, it has been tried to determine how the size of the primary bud and the cluster primordials in it change according to the position on one-year-old shoots. In this study, Vitis vinifera L. cv. ‘Karaerik’ and Vitis labrusca L. cv. 'Ülkemiz' varieties was used. Primary buds are separated from other shoot beds (secondary and tertiary buds) with the a scalpel, and fixation, vacuuming, paraffin impregnation, paraffin embedding, freezing, sectioning and tissue staining were performed, respectively. The stained samples were examined microscopically, images were taken and these images were transferred to the computer and histological analyzes was made. In the study, it was determined that bud sizes including three clusters were statistically different (p < 0.05) from other bud sizes (without clusters, one cluster and two clusters of buds). It was determined that there were statistical differences between cultivars in terms of both bud size and the number of cluster. In addition, it was determined that the middle (0.77) buds of the ‘Karaerik’ variety contained more clusters than the basal (0.66) and apical (0.59) buds, whereas the apical (1.19) buds of ‘Ülkemiz’ variety contained more clusters than the basal (0.88) and middle (0.98) buds. It is very important to know the structural features of the buds in order to make the right pruning application suitable for the variety.

Horticultural production systems have to move forwards to an environment-friendly and sustainable plant production. Basic substances can be added to reduce the use of synthetic plant protectant in conventional plant protection strategies. Regarding the protection of ornamental plants, less is known about the usage and behaviour of these alternative strategies and components. In our study, an infection of Podosphaera pannosa and Erysiphe polygoni in two different cultivars of cutting roses and one cultivar of French hydrangea was investigated. We studied the effect of a weekly foliar treatment of the basic substance chitosan (0.05 g/m2) compared to a water control and potassium hydrogen carbonate (VitiSan, Biofa GmbH, Münsing, Germany) in both production systems. As a result, in cutting roses as well as in French hydrangea, we found a significantly decreased infected leaf area following the use of chitosan and VitiSan compared to the water control. In both treatments, we found a stronger effect in French hydrangea, compared to roses. Results also indicate that the basic substance chitosan has to be used at a low pathogen level. We present a promising approach to reduce conventional plant protectants in ornamental plant production.
