“…However, in shoots produced vegetatively from microcuttings, Lamaoui et al [19] recommended the combination of 5 mg L −1 IBA and 1 mg L −1 NAA for root induction, whereas Koufan et al [17] recommended the combination of 0.5 mg L −1 NAA and 0.5 mg L −1 6-benzylaminopurine (BAP). On the other hand, Benbya et al [45] found that IBA is more effective than NAA in inducing adventitious roots from semi-hard wood cuttings. These divergent results could reflect different hormonal requirements among argan genotypes and explant types (juvenile, rejuvenated and adult material).…”

Argania spinosa (L.) Skeels is an endangered plant species endemic to Morocco. In recent years, attempts to develop in vitro regeneration systems for this species were made. However, rooting and acclimatization of in vitro plants have been a bottleneck for successful propagation. In the present study, the effects of different concentrations of auxins, putrescine, silver nitrate (AgNO3) and ammonium nitrate on the in vitro rooting of adventitious shoots of two argan genotypes “Mejji” and “R’zwa”, were evaluated. The highest rooting percentages (86.6% in “Mejji” and 84.4% in “R’zwa”) were observed on Murashige and Skoog (MS) medium modified by reducing the ammonium nitrate concentration and supplemented with 1.5 mg L−1 indole-3-butyric acid (IBA), 0.5 mg L−1 1-naphthalene acetic acid (NAA), 2 mg L−1 AgNO3 and 160 mg L−1 putrescine. This medium resulted in the development of a good root system after only 10 days of culture. Plantlet acclimatization was carried out using different substrate mixtures, and high survival rates (100%) were observed when the substrate contained either peat alone or a sand–peat mixture (1:1, w/w). The high percentages of rooting and acclimatization reported in the present study are of high importance for rapid and large-scale propagation of this endangered species.

“…The hastened rooting with increased leaf area has been documented in many tree species(Solis et al 2017;Caplan et al 2018;Mbibong et al 2019). Meanwhile, similar with T. scleroxylon,Dalbergia melanoxylon, and A. spinosa (Dick et al 2004; Amri et al 2010;Benbya et al 2018), the consistent lowest rooting ability for all parameters tested in cuttings from the top position is probably either due to low water retention with increasing susceptibility to water stress in cuttings or apical dominance that negates the rooting (Leakey 1983; Totaan 2019).…”

“…It was the middle position in the present study that yielded the best results in all parameters tested except on callus formation, which contrasts with other studies. For instance, best-rooting performance was found in cuttings taken from base for Dalbergia melanoxylon, Argania spinosa, and Antidesma bunius(Amri et al 2010;Benbya et al 2018;Totaan 2019) and from the top for Afzelia rhomboidea (Benabise 2012) and Stevia rebaudiana (Pigatto et al 2020). Such improvement in rooting success at the basal position was due to an established positive correlation between the increasing diameter of cuttings with increased carbohydrates reserves (Amri et al 2010), while to a low level of phenolic compounds and higher concentration of naturally occurring auxin in the apex for the top position (Hartmann et al 2010).…”

Shoots arising from the stump of a mature tree of Pterocarpus indicus Willd. were used to evaluate the within-tree variation in rooting induction. Collected rejuvenated stem cuttings were separated into three different positions (base, middle, and top) and treated with various indole butyric acid (IBA) concentrations (0, 500, and 1000 ppm). Cuttings were planted in an improvised rooting chamber for rooting induction. Results of the analysis of variance achieved non-significant effects (P > 0.05) due to IBA treatment in all rooting parameters evaluated after 33 d. In contrast, a highly significant increase in the number of roots (0.93, P = < 0.001) was detected in terms of cutting position, particularly at the middle part. Similarly, apart from callus formation (P > 0.05), significant increase in percent rooting (46.83%, P = 0.0012) and number of secondary roots (0.93, P = 0.0011) were obtained from the same position. Meanwhile, nonsignificant effects were also recorded in terms of IBA and cutting position interaction, except from callus formation (P = 0.036). Means separated by DMRT revealed that the interaction effect between middle position and IBA500 ppm (0.13) and those between top position and IBA1000 ppm (0.58) were significantly different. This study has proven the presence of withinstem variation; hence, rooting responses vary in cuttings collected from epicormic shoots arising from the stump of physiologically mature P. indicus.

“…Vegetative propagation is used to capture elite phenotypes as putative cultivars and has been evaluated in a number of important tree species in the region, including Prosopis africana [433], Argania spinosa [435,436], B. aegyptiaca [437,438], A. digitata [76] and V. paradoxa [136]. For instance, in Niger, Prosopis africana has been found to be amenable to air layering with no significant differences between the diameter classes and between the positions, although the success rate was low (28% after 4 months) [439].…”

Air layering has also been successful in B. aegyptiaca in Niger-93% after 2 months, with 83% survival [437]-while in Morocco, A. spinosa has been successfully propagated vegetatively by leafy semi-hardwood stem cuttings in studies examining the effects of nutrient solutions, auxins, cutting position and genotypes [435,436]. Basal cuttings treated with Hoagland solution had the best rooting (64%) with the most roots (45), allowing the selected elite trees to be successfully propagated.…”

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?
