Ferula gummosa Boiss.: Compatibility of Cultivating at Different Planting Dates

A factorial experiment, employing a completely randomized design with three replications, was conducted during the ۲۰۱۸-۲۰۱۹ growing season at the laboratory and greenhouse of Islamic Azad University, Shirvan Branch. The study aimed to evaluate the feasibility of cultivating the medicinal plant Galbanum (Ferula gummosa) at various planting dates. The first factor was the planting date, which included four levels: February ۲۰, March ۶, March ۲۱, and April ۴. The second factor involved four seed treatments: control, primed seeds, dormant seeds, and tissue culture. The traits measured in the study were leaf number, leaf length, tuber length, dry weight, and survival percentage. Results indicated that both planting date and seed treatment significantly affected all measured traits (P≤۰.۰۱). Additionally, the interaction between planting date and seed treatment significantly influenced survival percentage (P≤۰.۰۵). Mean comparisons showed that the highest values for leaf number, leaf length, tuber length, dry weight, and survival percentage were achieved with the February ۲۰ planting date combined with the seed priming treatment. Correlation analysis revealed significant positive relationships between leaf length and tuber length (۰.۸۷۹), leaf length and plant dry matter content (۰.۵۲۲), tuber length and plant dry matter content (۰.۷۰۷), tuber length and survival percentage (۰.۴۰۶), and plant dry matter content and survival percentage (۰.۵۰۹). Stepwise regression analysis indicated that plant dry matter content was the first variable included in the model, accounting for ۲۶% of the variation in survival percentage. Leaf number was the next variable, and together, these two traits explained ۳۳% of the variation.iven these findings and considering the importance of planting date for cultivating Galbanum in Northern Khorasan Province, the February ۲۰ planting date combined with seed priming is recommended as the optimal treatment for maximizing production.
