| چکیده انگلیسی مقاله |
Artemisia umbelliformis Lam. is an alpine herbaceous species which grows in the wild and used in the production of the génépi’ liqueur, and with interest as ingredient in other food products. The propagation and cultivation have become the only way to ensure a supply chain for this plant, preserving the natural habitats. However, seed propagation is limited by low germination. Selected seeds and fine-tuned agrotechniques are requested by the nursery production system. We investigated seed germination ability (final germination percentage - FGP, first germination time - FGT, halftime of germination - T50, germination period - GPD, and mean germination time - MGT) and early seedling development of three wild A. umbelliformis populations (Valnontey, Soana and Urtier), by testing three germination substrates with different peat and perlite ratio (v:v) (S1, 100:0 ; S2, 80:20; S3, 60:40), in combination or not with two generalist arbuscular mycorrhizal fungi (AMF) species (Rhizophagus intraradices and Funneliformis mosseae). Results highlighted variability in germination capacity according to the genotypes, indicating the Valnontey population as superior to Soana and Urtier in FGP (34.0 %, 7.2 % and 8.6 %, respectively), FGT (8.7, 13.2 and 14.1 days, respectively), MGT (12.5, 16.5 and 17.1 days, respectively) and T50 (13.8, 17.4 and 16.8 days, respectively). Among the substrates, S3 led to a higher FGP (22.9 %) than the others (11.4 % and 15.6 % in S1 and S2, respectively), thus resulting preferable. No AMF symbiosis was highlighted; therefore, the advantage of applying bioinoculants to improve génépi production should be further investigated. |
