Saffron is appreciated by its colour, taste, and aroma. To examine the effect of abiotic and biotic stress on these main properties, in the span of 2014-2016, saffron stigmas were collected from major different saffron cultivation areas of Iran and saffron quality was estimated. The quality of saffron was assessed by ultraviolet-visible spectroscopy following the ISO3632:2011 standard. However, the composition and concentration of crocetin esters, picrocrocin, safranal, and kaempferols, the most critical compounds determining the properties and quality of saffron can vary with the geographical origin and virus effects, being more accurate High-Performance Liquid Chromatography and Diode Array Detection (HPLC-DAD) methods were used to analyze saffron quality. Using HPLC-DAD we analyzed saffron plants grown at various conditions (considering altitude, temperature, and precipitation/rainfall) and in presence/absence of virus infections; we found that edaphoclimatic and cultivation conditions significantly determine the quality of the spice and the presence of virus modifies the content of its metabolites.

Saffron ( L.) is one of the most expensive spices in the world due to its strong market demand combined with its labor-intensive production process, which needs a lot of labor and has significant costs. New cultivation methods and traceability systems are required to improve and valorize local Italian saffron production.

Background: Crocetin is a multifunctional apocarotenoid natural product derived from saffron, holding significant promises for protection against various diseases and other nutritional applications. Historically, crocetin has been extracted from saffron stigmas, but this method is hindered by the limited availability of high-quality raw materials and complex extraction processes. To overcome these challenges, metabolic engineering and synthetic biology can be applied to the sustainable production of crocetin.

Backgrounds: Osteoarthritis (OA) significantly impacts the elderly, leading to disability and decreased quality of life. While hyaluronic acid (HA) and chondroitin sulfate (CS) are recognized for their therapeutic potential in OA, their effects on extracellular matrix (ECM) degradation are not well understood. This study investigates the impact of HA and CS, individually and combined, on ECM degradation in OA and the underlying mechanisms.

A two-year study has been conducted to optimize saffron cormlet production in a soilless cultivation system. Variations in the concentration of phosphate, boron, and irrigation events were assessed in the first year. Subsequently, after optimizing the substrate composition, the effects of nutrient solution volume and the concentration of nitrate, iron, and boron were investigated on the yield and weight of cormlets and leaves, photosynthetic activities, and productivity of nutrient solutions in the second year.

Background: Relatively few studies have explored the impact of biofertilizers on the qualitative and quantitative yield of saffron despite its global agricultural and medical importance. This study aimed to evaluate the physiological and phytochemical responses of saffron to potassium (K), phosphorus (P), and iron-zinc (Fe-Zn) biofertilizers over 2 consecutive years (2022-2023). The treatments included single and combined applications of K, P, and Fe-Zn biofertilizers containing active bacterial inoculum, along with a control group, resulting in a total of eight treatments.
