Sumac (R. coriaria L.) is a subtropic and temperate climate plant with medicinal and aromatic properties which has a natural distribution in many regions of Anatolia. Sumac which is used as a food additive in the food industry due to the flavoring substances has been in high demand in recent years. Besides the beneficial secondary metabolites, it is used in the field of medicine and pharmacy. Sumac (R. coriaria) which grows spontaneously in the natural environment without any agricultural practices is collected by the local people in the region and supplied to the local market. Since this situation, the ideas of creating modern orchards for sumac have begun to emerge. For this reason, selection breeding studies have been planned in sumac (R. coriaria L.). This study was carried out at the East Mediterranean Transition Zone Agricultural Research Institute during 2019-2021 years. Approximately 300 different sumac genotypes were observed and botanically 92 genotypes were found positive in this study. It was determined that the wet weight values of the clusters in the examined sumac genotypes varied between 5.63-87.74 g as a result of the statistical analysis. The highest cluster weight varied between 87.74, 78.92, and 70.81 g in GN26, GN86, and GN90 genotypes respectively. The lowest cluster wet weight was found in GN28 (5.63 g) and GN41 (6.00 g) genotypes in the study. It was found in the study that the cluster powder efficiency values varied between 30.62% and 72.49% and the average cluster powder efficiency was 49.15%. It was determined that the results obtained from about 20 sumac genotypes were found to be positive in the statistical analyzes made on the characteristics examined in this study. It is aimed to use this sumac (R. coriaria L.) genotypes in the modern sumac cultivation planned for the future.

This study was carried out to investigate the intake of macro plant nutrients from the soil of rootstocks that are considered promising in the wild plum rootstock breeding project carried out in Malatya and Elazığ provinces. The study was completed in 2020 on the land of the Malatya Apricot Research Institute and the laboratories of the Kahramanmaraş East Mediterranean Transitional Zone Agricultural Research of Institute. According to the analysis results of the soil samples taken from 0-30 cm and 30-60 cm depths of the experimental area, it was determined that the concentrations of other nutrients except available phosphorus were in very good condition. As a result of the analysis of leaf samples taken from 69 rootstocks selected in June, scoring was made by applying measured grading to the amounts obtained. This method has been applied for the first time in the world with this study. At the end of the study, it was determined that phosphorus varied between 0.16-0.55%, potassium 0.80-2.40%, calcium 0.41-3.48% and magnesium 0.15-0.49% in leaf contents. These values compared to other literature data, it was observed that phosphorus and potassium were high and calcium and magnesium were low.

This study was conducted in the laboratories and greenhouses of Eastern Mediterranean Transitional Zone Agricultural Research Institute between 2018 and 2020 to identify botanical characteristic of PCPM (Prunus cerasifera X Prunus microcarpa), which is natural hybrid of Prunus cerasifera (PC) and Prunus microcarpa (PM), and to investigate slip production opportunities of it at different IBA 1000 mg L-1, 2000 mg L-1, 3000 mg L-1, 4000 mg L-1. PCPM which was noticed in its natural environment, was followed in botanical terms for 3 years. It was determined that the average fruit weight, fruit width, and fruit length values of PCPM were 1.33 g, 11.93 mm and 12.50 mm, respectively.The soluble solid contents (SSC) values were measured as 15.03 brix in PC, 25 brix in PM, and 27.66 brix in PCPM. It was determined that the annual shoot development was 124.98, 8.41, and 26.15 cm, and the leaf lengths were 64.99, 21.18, and 41.93 mm in PM, PC, and PCPM, respectively. It was also determined that PCPM showed a botanic characteristic between PM and PC, which are its parents in general botanical terms. In rooting with hardwood cutting for PCPM, it showed similar values with Myrobolan 29C, which was the control rootstock, and had average rooting percentage as %80.11, and the average number of roots as 5.27 pcs/slip. The results had a positive effect on rooting increase in hormone application of 2000 mgL-1 concentration with IBA compared with other applications.

This study was conducted to investigate the intake of micro plant nutrients of promising genotypes in the selection study of some wild plums that can be rootstock for apricots in Malatya and Elazığ region. The study was carried out in 2020 on the land of Malatya Apricot Research Institute and in the Soil, Plant and Water Analysis Laboratory of the Kahramanmaraş Eastern Mediterranean Transitional Zone Agricultural Research Institute. Soil samples were conducted from 0-30 cm and 30-60 cm depths in order to determine the micronutrients in the soil from the area where the trial was established. According to the analysis results, it was determined that the micronutrient elements examined in the top soil (0-30 cm), except boron, were at sufficient levels. As a result of the analysis of leaf samples taken from 69 rootstocks selected in June, scoring was made by applying weighted grading to the amounts obtained. This method has been applied for the first time in the world with this study. At the end of the study, in the leaf contents, iron 33.65-101.00 mg kg-1, manganese 19.01-106.27 mg kg-1, copper 4.15-13.03 mg kg-1, zinc 9.25-35.55 mg kg-1 and boron 19.54-35.55 mg kg-1 varied between. It has been determined that obtained these values are highly similar to the reference values, and when compared with other literature data, manganese is high, iron is relatively low, and other micronutrients elements are sufficient.
