Abstract: 

This research was conducted during the seasons 2022 and 2023 at the Agricultural Scientific Research Center in Amrit- Tartous on saffron (Crocus sativus L.). The research included studying the effect of three treatments of corms weight (2-4, 4-6, 6-8 g) on vegetative growth, the number of flowers and daughter corms, and on the content of the stigmas of active substances. The  field experiment was carried out according to a randomized complete block design with four replications.  The results showed a significant superiority of the weight of 6-8 g over the two weights 4-6 g and 2-4 g, that recorded the highest value for the length of leaves (40.51 cm), the number of leaves (18.44 leaf per plant^-1), the leaf area of plant (172.58 cm²) and the highest number and weight of the daughter corms (3.13 corms per plant^-1, 17.79 g per plant^-1 respectively) in the second agricultural season. Corm weight of 6-8 g, was significantly superior over the corm weight of 4-6 g in number of flowers and the dry weight of stigmas) 16.55 flower.m^-2, 0.062 g.m^-2 respectively), and in the best ratios of the active substances crocin, picrocrocin and safranal (E^1% 440 nm =197.54 , E^1% 257 nm= 60.09, E^1% 330 nm = 38.34 respectively).

Keywords: saffron, corm weight, stigma, active substances, productivity.
