“…Our results show that the CEC increase has negative effects on some productivity parameters studied and has no relation to others. On the other hand, the ordinary effects of a high CEC increases soil fertility [38], which increases productivity on all levels [39][40][41][42]. A strong correlation was detected between the length and the diameter of argan in several ex situ tests [42].…”

The argan tree, which is found in southern Morocco, is characterized by environmental, economic and nutritional benefits, but the growth of this tree is very slow. This makes it necessary to find methods to accelerate its growth. A pot experiment was conducted to evaluate the effects of biochar (BC) and bio-compost (CP) each applied at the rate of 0, 3 and 6% (M/M) on starting growth of argan in fine silty soil for sixteen months. Main stem length, diameter, durability ratio, total length of all stems and number of sprouted shoots were measured every two months with two photosynthetic measurements spaced five months apart for each argan seedling. Despite the strong signs of epigenetic sensitivity and genetic variability across the argan behavior of each treatment depending on the duration and environmental conditions of the crop and the large standard deviations marked in all the tests that were conducted on the argan, some treatments showed interesting results, even in terms of the interaction between climatic conditions, type of treatment and type of test. The argan plants which were grown in the substrate at 6% BC 3% CP showed significant results for all the growth parameters studied and throughout the test. This mixture marked an average water holding capacity (WHC) of around 0.66 g H2O/g dw; the argan seedlings showed the best perimeter average, which exceeded 2.7 cm in the last measurement, with a ratio (height/diameter) strictly less than 7, which removes any possible problem of argan filiform. However, argan plants from all treatments were not stable in the growth characteristics studied; each treatment has advantages and disadvantages regarding argan. Transplantation and monitoring in the field of argan seedlings that have had interesting results are strongly recommended to see if the good starting growth influences their development in the field or if it is a temporary effect.

“…There are also ideas based on the molecular polymorphism of the species, explained by the human action that would have dispersed the species for its economic and ethnobotanical interest (El Mousadik and Petit 1996). Despite the open debate about the possible fragmentation of its natural distribution area, different sources agree on the subspontaneous nature of these populations (Msanda et al 2005; López-Sáez and Alba-Sánchez 2009; Kechairi and Benmahioul 2019). Some localities may even respond to ancient cultivation attempts.…”

Bioclimatic habitat limitations for argan trees (Argania spinosa (L.) Skeels) in Northern Africa and Spain

et al. 2022

Argania spinosa L. Skeels is an Algerian-Moroccan endemic tree. This species is part of various plant communities consisting of Mediterranean, Macaronesian and Saharan floristic elements. It has been introduced and perhaps sometimes naturalized in various regions of the Mediterranean basin. Due to its role in combating desertification, high socio-economic value, and traditional use as fodder and food, the southwestern Moroccan argan grove (Arganeraie) was declared Biosphere Reserve. It had already been subject to conservation and reforestation programs a century earlier. Its cultivation for oil production could be, besides an economic objective, an effective method to conserve its genetic diversity. Therefore, this study aims to estimate its potential distribution and establish efficient breeding programs by determining its ecological requirements, identifying its different habitats, and predicting habitat suitability models for Morocco, Algeria, Tunisia, and Spain. Using 53 occurrence points, wind speed and direction data, and 29 bioclimatic variables, multivariate methods were applied to describe the ecological profiles and characterize the heterogeneity of its habitat to subsequently, train a Maxent model that establishes, besides Morocco and Algeria, suitable cultivation areas in Tunisia and Spain. The North African potential area is limited to the western Mediterranean coast of Algeria and flat and coastal areas of eastern Tunisia. The increased likelihood of suitability remains in the southeast Iberian Peninsula. A high probability of argan cultivation is also evident in the Canary Islands. These results provide possibilities for future expansion of argan crop and a window of opportunity to improve its genetic diversity and conservation.

“…Other populations are found in Algeria in the Tindouf region (Khallouki & al. 2017;Kechairi & Benmahioul 2019). The range is in the transitional area between the Mediterranean iso-climatic zone in the north and the Saharan region in the south and has a wide opening to the Atlantic Ocean (Msanda & al.…”

“…A preliminary bibliographic search was undertaken to highlight the sites of the wild plant populations of Argania spinosa. The Moroccan populations have been chosen as a reference because the range in Algeria has been enlarged by man and many populations have been artificially reinforced (Kechairi & Benmahioul 2019). For trees favoured or cultivated by man, sometimes for millennia, it is necessary to develop approaches combining phylogeography and paleoecology at the scale of the distribution area (Médail & al.…”
