“…It has been found that the nutrient concentrations of damask roses from conventional gardens are significantly higher than those from organic gardens, particularly for nitrogen (N), K, calcium, and iron concentrations, representing the accumulation of inorganic substances. Paclobutrazol, an antigibberellic, combined with N supplied in appropriate amounts, and the micronutrients Mn 2+ , Zn 2+ , and Cu 2+ , improved flower bud formation and flowering, and rose oil yield having a higher percentage of citronellol [67]. Farmers must decide upon the choice of conventional or organic agricultural system based on the benefits and challenges of the agricultural sector.…”

Roses are popular ornamental plants all over the world. Rosa damascena Mill., also known as the damask rose, is a well-known scented rose species cultivated to produce essential oil. The essential oils obtained are high in volatile organic compounds (VOCs), which are in demand across the pharmaceutical, food, perfume, and cosmetic industries. Citronellol, nonadecane, heneicosane, caryophyllene, geraniol, nerol, linalool, and phenyl ethyl acetate are the most important components of the rose essential oil. Abiotic factors, including as environmental stress and stress generated by agricultural practises, frequently exert a selective impact on particular floral characteristics, hence influencing the overall quality and quantity of rose products. Additionally, it has been observed that the existence of stress exerts a notable impact on the chemical composition and abundance of aromatic compounds present in roses. Therefore, understanding the factors that affect the biosynthesis of VOCs, especially those representing the aroma and scent of rose, as a response to abiotic stress is important. This review provides comprehensive information on plant taxonomy, an overview of the volatolomics involving aromatic profiles, and describes the influence of abiotic stresses on the biosynthesis of the VOCs in damask rose.

The aim of this study was to establish whether the type of the agricultural system has any influence on the essential oil production and antioxidant activity of industrial cultivated Rosa damascena Mill. in the Rose valley, Bulgaria. Six private farms from Kazanlak (Rose) Valley, Southern Bulgaria were included in the study conducted in the period 2019–2020. The first three selected farms are designated within the conventional farming and the other three are certificated as organic farms. GC/FID and GC/MS analyses were performed; the contents of total polyphenols and flavonoids in the methanol extracts from rose petals were determined. Additionally, the antioxidant activity of rose extracts was evaluated by four reliable methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2´-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC) assays. The impact of the agricultural system on the essential oil composition and antioxidant activity was evaluated by ANOVA statistical analysis. The results obtained showed that organic farming produced essential oil with a higher linalool and geraniol content and lower β-citronellol + nerol concentrations than conventional farming. It was found that organic farming production demonstrated a better antioxidant activity evaluated by the three DPPH, ABTS, and CUPRAC methods according to the averaged data for two years, 806.82, 797.66 and 1534.40 mM TE/g dw versus 510.34, 521.94 and 917.48 mM TE/g dw for CF, respectively, with high statistical significance for the DPPH and ABTS analyses. Consequentially, the rose extracts from the organic farming accumulated more phenolic compounds that corresponded to the higher antioxidant potential of the organic roses.

In the study, the changes in the structural stability and erodibility properties of the organic regulators (TG, TAGG and SG) applications to serpentine soils were investigated. In line with the study's objective, organic amendments based on oven dry weight were applied to the soils in different dose combinations. The study, designed according to a completely randomized design (CRD) was conducted in plastic pots maintained under greenhouse conditions. Six months after the experiment was established, the pots deteriorate pots were and the necessary measurements were made. WAS, DO, EO, SSI, OM values were measured to evaluate the change in the erosive and structural stability of the soils. As a result of the study, the OM values of the soils increased with the organic regulator applications (TAGG, TG, SG). The highest increase was observed in pots where TG and TAGG were applied. The erodibility parameters of the soils, DO and EO, showed a decrease with increasing dosage applications. WAS and SSI parameters, which are soil erosive variables, increased with increasing application dose. These increases (WAS, OM, SSI) and decreases (DO and EO) depending on the applications were statistically significant (p
