Abstract
Seed treatment with Trichoderma spp. has shown to enhance plant growth and alleviate abiotic stress, but its application on endemic species, such as argan (Argania spinosa), remains underexplored. This study investigates the effect of a Trichoderma spp. bioformulation on argan seedling growth under greenhouse conditions over 12 months. Significant improvements were observed in treated seedlings, including increased length, dry matter of both root and shoot, and branch number. Root and vegetative fresh weights reached 12 g and 14 g, respectively, compared to 2 g and 3 g in control plants. Additionally, root and vegetative lengths were 44 cm and 74 cm, respectively, outperforming control seedlings at 35 cm and 25 cm. Treated seedlings also showed a higher number of branches and crown diameter, with survival and colonization rates of Trichoderma spp. in root tissues reaching 95%. These results suggest that Trichoderma spp. seed treatment can significantly promote the growth and development of young argan seedlings.
