Coban, Furkan; Gül, Volkan; Çakır, Ahmet
Achillea biebersteinii Afan., a medicinal and aromatic plant widely distributed in Türkiye, is valued for its essential oil content and bioactive compounds. This study aimed to investigate the phenotypic variation, yield performance, and essential oil content of A. biebersteinii populations collected from ten different locations in northeastern Türkiye. A total of six morphological and agronomic traits plant height (PH), inflorescence diameter (ID), stem diameter (SD), number of flowering branches (NFB), dry herbage yield (DHY), and dry flower yield (DFY) alongside essential oil content (EO), were evaluated. ANOVA results revealed statistically significant differences among locations for PH, DHY, and NFB, indicating strong environmental or genetic influences. In contrast, EO content showed no significant variation across locations, suggesting greater genetic stability. Correlation analysis indicated a strong positive association between NFB and DHY, while EO content was negatively correlated with PH and SD. Principal Component Analysis further clarified trait associations and revealed distinct groupings among locations, with L9 and L10 showing superior yield performance and L3 standing out for its high EO content. These findings highlight the substantial phenotypic and chemotypic diversity of A. biebersteinii in northeastern Türkiye and underscore the importance of location specific selection in breeding and conservation programs. The identification of high-yielding and high-quality populations provides a valuable resource for sustainable utilization of this species in medicinal and aromatic plant sectors.

In the present study, to promote sustainable nano-farming, the apparent effects of different concentrations (0, 100, 200, 300, 400, 500 ppm) of titanium dioxide nanoparticle (TiO2NPs) solutions on the germination percentage, index and duration of seeds belonging to Balcı, Dincer, Hasankendi, Koc, Olas, and Zirkon safflower varieties were investigated. Moreover, scanning electron microscopy (SEM) was employed to analyze TiO2NPs in germinated safflower varieties. Germination performance was TiO2NPs concentration and variety depended. It was determined that the seed samples displayed different responses to TiO2NPs concentrations; germination percentages were between 20.0±1.15 and 82.9±0.44%, germination durations were between 2.01±0.021 to 3.82±0.017 days, and germination indices were between 9.97±0.606 and 38.97±0.959. While the highest germination percentage (82.9±0.44%) was obtained from Dincer variety with 100 ppm TiO2NP pre-application, the lowest germination percentage (20.0±1.15% and 20.0±1.92%) was obtained from Balcı and Hasan Kendi varieties with 100 and 300 ppm TiO2NP pre-application. According to this result, although the highest germination percentage based on variety was obtained from the Dincer variety, the Balcı variety with the lowest germination percentage provided the most significant increase in the 200 ppm TiO2NPs application dose compared to the control. According to the germination percentage, it can be said that the most effective TiO2NPs application dose in Safflower varieties is 200 ppm. Further research on nanoparticles is needed to determine both the economical doses of TiO2NP pre-application and its uptake by the plant.

This study aimed to determine the effects of titanium dioxide nanoparticle (TiO2NP) pretreatment on seeds of different safflower cultivars (Balci, Dinçer) under salt and heat stresses. The apparent effects on stress markers (malondialdehyde (MDA), hydrogen peroxide (H2O2) and superoxide radical (O2 •⁻) content), as well as changes in germination and physiological parameters (radicle and plumula weight and length measurements), were investigated. TiO2NP pretreatment caused an increase in radicle length and plumula fresh weight for the Balci cultivar under salinity. Furthermore, plumula dry weight was alleviated with TiO2NP pretreatment for both cultivars. TiO2NP pretreatment improved plumula dry and fresh weights for both cultivars under heat stress. In addition, MDA content decreased for both cultivars under heat stress but only for Balci under salt stress. The amount of O2 •⁻ radicals positively affected only the radicle for both cultivars under heat stress. This study is the first to document the alleviation of salt stress damage for the Balci safflower cultivar, and protection for both Balci and Dinçer cultivars under heat stress, using 200 ppm TiO2NP pretreatment.

Microbial fertilizers containing Bacillus subtilis and Bacillus megaterium isolates are one of the important organic fertilizers, which strengthen the immune system of plants against harmful effects and promote the plant growth by fixing nitrogen from the atmosphere, to obtain better quality products. This study was conducted to determine the effects of different liquid microbial fertilizer doses (0, 500, 1000, 1500, 2000, and 2500 ml 100 L–1) on the yield and yield components of the coriander (Coriandrum sativum L.) grown in Bayburt in 2018 and 2019. The experiment was set up as three replicates in randomized complete block design. The results indicated that there was a considerable variation in the yield and yield components of coriander, and the yield significantly increased as the dose of microbial fertilizer was increased. The maximum essential oil content and seed yield were recorded for the plots grown under the F1 and F3 treatment. It was found that the maximum seed yield was obtained in the F3 treatment (839.0 kg ha–1), and the seed yield decreased in the F4 (754.1 kg ha–1) and F5 (759.9 kg ha–1) treatments. Although the increase in the microbial fertilizer dose increases seed yield, using the fertilizer in optimum dose can be more profitable. Therefore, this study suggests that the fertilizer dose “F3” can improve the productivity of the coriander grown in the areas treated with microbial fertilizer.
