Apricot is a species that is difficult to propagate and root vegetatively. Thus, it has so far been propagated by grafting on heterogeneous seedling rootstocks. There is currently no clonal rootstock in apricot (Prunus armeniaca) species. This study primarily aimed to develop a P. armeniacarootstock that can be propagated clonally under in vitroconditions. Within the scope of the study, in vitropropagation possibilities of the 42-01 genotype (P. armeniaca) were investigated. The explants were taken to be cultured in nutrient media (MS, ½MS, NRM, and ½NRM) containing different concentrations and combinations of BA (0.0, 0.5, and 0.1 mg l−1), IBA (0, 0.01, and 0.025 mg l−1), and GA (0.5 mg l−1). During the study, plant vitality, shoot number, shoot length, rooting rate, root number, and root length were recorded. Except the MS medium (38.90%) containing 0.0 mg l−1BA + 0.01 mg l−1IBA +0.5 mg l−1GA and the NRM medium (30.56%) containing 0.0 mg l−1BA + 0.025 mg l−1IBA + 0.5 GA, all the treatments resulted in a mean plant vitality ranging from 69.44 to 100%. The highest rooting rate was achieved as 61% in the ½MS medium containing 2.0 mg l−1IBA. In terms of the root length, the ½NRM + 2.0 mg l−1IBA treatment gave the best result and was measured as 2.46 cm. According to the results obtained, it can be said that the genotype 42-01 can be a clonal rootstock candidate in apricot.

In this study, the effects of different NaCl levels (0, 50, 100, 150 mM) on ‘Viking’ aronia variety plants in the in vitroculture medium were investigated. In the study, aronia plantlets were cultured in the MS and the ½MS rooting media with 1 mg l−1IBA supplemented with different concentrations of NaCl for 35 days. At the end of salinity stress treatments, plant height, leaf area, plant fresh and dry weight, rooting rate, root number, root length as well as root fresh and dry weight were measured. In all measurements recorded for salinity stress, there was a decrease in all growth parameters as the NaCl level increased in both media. The ½MS medium compared to the full MS medium performed better at almost all growth parameters at every NaCl concentration. The average highest plant height was recorded in the control treatment (4.77 cm) of the ½MS medium; the lowest plant height was recorded in 150 mM NaCl treatment (1.67 cm) of the MS medium. The lowest leaf area was determined at 150 mM NaCl concentration, and it reduced 68.8% in the MS medium and 73% in the ½MS medium. Rooting was highest in the control groups (100%) in both media; a significant gradual decrease occurred in 50 and 100 mM NaCl concentration, and rooting did not occur in 150 mM NaCl treatment. In addition, with increasing salt concentration in the culture medium, both root length and number decreased. Consequently, it has been determined that the ‘Viking’ aronia variety is sensitive to high salinity levels.

Obesity and eating disorders commonly co-occur and might share common risk factors. Appetite avidity is an established neurobehavioural risk factor for obesity from early life, but the role of appetite in eating disorder susceptibility is unclear. We aimed to examine longitudinal associations between appetitive traits in early childhood and eating disorder symptoms in adolescence.
