In this study, it was aimed to examine the rooting performance of hardwood cuttings taken from the promising black mulberry genotypes Kemalpaşa, Yelpe, Merkez 3, Merkez 6, Kocacık, Çamdere, and Merkez 7 determined in the province of Tokat under the same environmental conditions. All cuttings were immersed in 6000 ppm IBA solution for 5 seconds before planting and planted on heated bottom tables. The cuttings, which were kept in rooting units for about 3 months, were then removed and measurements were made on them. As a result of the study, statistically, differences were found in root length, root diameter, root number, callus formation rate and rooting rates in the parameters examined. There was no statistically significant difference between genotypes in decay rates. Decay rates of genotypes are between 12.96% - 41.67%, callus formation rates are between 70.83% - 95.39%, rooting rates are between 60.41% - 92.64%, root lengths are between 5.85 - 7.52 cm, root diameters are between 1.42 - 1.75 mm, and root numbers are between 7.87 - 12.67 root/cutting has taken values. In the light of the information obtained as a result of the study, it was determined that Yelpe, Çamdere, and Merkez 6 genotypes showed high rooting success. These results are important in terms of shedding light on the research to be done in order to determine the various studies and the performance of the saplings. It is also a determining factor for enterprises producing saplings.

Difficulties in adventitious root formation in blackberry (Rubus fructicosus L.) cuttings create a disadvantage for producers. The aim of this study is to investigate the effect of different growth regulator applications on the rooting ability of blackberry hardwood cuttings in order to avoid this problem. The experiment was carried out in the polycarbonate greenhouse of Tokat Gaziosmanpaşa University Agricultural Research and Application Center In the experiment, in addition to the control (pure water) group, Indole-3-Butyric Acid (3000 ppm IBA) and different doses of paclobultrazole (500 ppm PBZ1, 1000 ppm PBZ2, 1500 ppm PBZ3) were applied to hardwood cuttings separately and in combination. After the application, the cuttings were planted in perlite medium and left to root for 90 days. At the end of this period, in the cuttings removed; rooting rate, callus formation rate, root number, root length and root diameter parameters were examined. As a result of the study, the highest rooting rate was obtained from the IBA applied cuttings (%42.22), followed by the PBZ1 applied cuttings closest (%33.33). In addition, it was determined that PBZ applications had positive effects on root diameter compared to the control group. The results obtained are important in terms of contributing to the literature and benefiting the enterprises

Development of an efficient plant regeneration protocol is essential for vegetable crop advancement by biotechnological methods. In this study, regeneration protocols of four pepper lines of different pepper types were optimized. Different protocols for organogenesis were investigated in regeneration experiments. Optimum plant regeneration was obtained in different combinations of 6-Benzylaminopurine (BAP) and Indole-3-acetic acid (IAA) in organogenesis assays. In organogenesis experiment, the highest shoot development was determined as 80% from hypocotyl explant of Demre pepper in 4 mg L-1 BA+0.5 mg L-1 IAA, 80% from hypocotyl explant of Charleston pepper in 3 mg L-1 BA+0.5 mg L-1 IAA, 80% from hypocotyl explant of capia pepper in 5 mg L-1 BA+0.5 mg L-1 and 84% from hypocotyl explant of bell pepper in 5 mg L-1 BA+0.5 mg L-1 IAA. Afterward, shoots were rooted and whole plants were obtained.
