“…Similar to this study, Atyane et al. (2017) found that picrocrocin, safranal, and crocin content differed between saffron samples from different altitudes. Lage and Cantrell (2009) determined altitude to be the only factor significantly affecting crocin content.…”

This study aims to identify factors that affect saffron quality in order to enhance the quality and production of saffron. Saffron samples were collected from 38 harvest sites at various altitudes (high, medium, and low) in Taliouine and Taznakht. Analysis of the content of safranal, crocin, and picrocrocin was carried out through spectrophotometry in the ultraviolet‐visible (UV–vis) according to the ISO 3632‐1:2011 standard. Saffron from high‐altitude sites was found to have the highest average content of picrocrocin (90.92 ± 5.98), safranal (28.57 ± 2.52), and crocin (208.37 ± 21.27), followed by that from medium‐altitude sites (87.59 ± 8.22, 27.09 ± 3.69, and 200.05 ± 19.86, respectively). Analysis of variance test showed that the quality of the saffron was influenced by the altitude and not by the species provenance. Principal component analysis (PCA) indicated that saffron containing the highest quantity of crocin was found to have the greatest coloring strength and consequently belonged to the first grade. Partial least squares (PLS) regression allowed finding a suitable preliminary model to predict the coloring strength from the absorbances. Overall, these findings can be used to improve the quality and quantity of saffron by developing the conditions of saffron cultivation, especially at high altitude. Novelty impact statement The investigation of Moroccan saffron showed that his quality is affected by the altitude and not by the provenance, and that the high altitude containing the first grade of saffron. The moisture content showed an effect on saffron quality. PCA identified a strong correlation between crocin, coloring strength, and saffron grade. Thus, the saffron with the highest amount of crocin had the highest coloring strength and therefore belonged to the first grade. PLS regression was successfully created as a preliminary model to predict coloring strength based on their absorbance data in these study areas.

“…Regarding environmental conditions, soil is the most important factor stimulating secondary metabolites, as it controls the movement and availability of air, nutrients and water. Atyane et al (2017) [ 21 ] showed that the chemical composition of saffron is influenced by geographical origin, soil and climate. In addition, Mykhailenko et al (2020) [ 22 ] reported that soil type, altitude, temperature, irrigation cycles and harvesting periods affect the accumulation of compounds in saffron plants used as medicinal and pharmaceutical raw materials and food additives.…”

Climate and soil are important factors that affect the quality of saffron. Saffron quality is determined by the marked content of secondary metabolites. The objective of this work was to study the effect of soil physicochemical properties on the secondary metabolites of saffron. Our study concerned the analysis of saffron samples by high-performance liquid chromatography-detection by diode array (HPLC-DAD). Soil samples were analyzed by physicochemical methods, ED-XRF fluorescence and X-ray diffraction to determine the different types of clays. Saffron samples grown in loam–clay–sand soils contained high values of crocins and kaempferol 3-sophoroside 7-glucoside but low values of safranal. In addition, saffron samples grown in soils rich in organic matter, phosphorus and potassium contained high values of crocins and kaempferol 3-sophoroside 7-glucoside but low values of safranal. This original approach was carried out for the first time in our study, both by ED-XRF fluorescence and by X-ray diffraction, to determine what elements affect the quality of saffron. Thus, we concluded that clays containing low amounts of iron could have a positive effect on the coloring strength of saffron.

“…For example, soil rhizosphere fungi received photosynthates from host plants and, in turn, helped host plants increase their absorption of nutrients (nitrogen and phosphorus), thus affecting the secondary metabolism of host plants and ecological functions (Lau and Lennon, 2011 ; Bennett et al, 2017 ; Jiang et al, 2017 ). Regarding various environmental conditions, soil is the most important factor in stimulating secondary metabolites, as it controls the movement and availability of water, air, and nutrients (Atyane et al, 2016 ; Yang et al, 2018 ; Xiao et al, 2022 ). Several studies have shown that soil type and cultivar influence the available nitrogen, phosphorus, potassium, and organic carbon content of rhizosphere soil, thereby affecting rhizosphere microbial communities, plant growth, and secondary metabolites (Sampaio et al, 2016 ; Ren et al, 2022 ; Hou et al, 2023 ).…”

Golden buckwheat (Fagopyrum dibotrys, also known as F. acutatum) is a traditional edible herbal medicinal plant with a large number of secondary metabolites and is considered to be a source of therapeutic compounds. Different ecological environments have a significant impact on their compound content and medicinal effects. However, little is known about the interactions between soil physicochemical properties, the rhizosphere, endophytic fungal communities, and secondary metabolites in F. dibotrys. In this study, the rhizosphere soil and endophytic fungal communities of F. dibotrys in five different ecological regions in China were identified based on high-throughput sequencing methods. The correlations between soil physicochemical properties, active components (total saponins, total flavonoids, proanthocyanidin, and epicatechin), and endophytic and rhizosphere soil fungi of F. dibotrys were analyzed. The results showed that soil pH, soil N, OM, and P were significantly correlated with the active components of F. dibotrys. Among them, epicatechin, proanthocyanidin, and total saponins were significantly positively correlated with soil pH, while proanthocyanidin content was significantly positively correlated with STN, SAN, and OM in soil, and total flavone content was significantly positively correlated with P in soil. In soil microbes, Mortierella, Trechispora, Exophiala, Ascomycota_unclassified, Auricularia, Plectosphaerella, Mycena, Fungi_unclassified, Agaricomycetes_unclassified, Coprinellus, and Pseudaleuria were significantly related to key secondary metabolites of F. dibotrys. Diaporthe and Meripilaceae_unclassified were significantly related to key secondary metabolites in the rhizome. This study presents a new opportunity to deeply understand soil-plant-fungal symbioses and secondary metabolites in F. dibotrys, as well as provides a scientific basis for using biological fertilization strategies to improve the quality of F. dibotrys.
