“…The increasing regeneration rates and quicker emergence of buds and leaves in non-mist poly-propagators obtained in this study may be explained by the uniform and relative high temperature and humidity that characterized this propagation system (Leakey 2014a).The greatest mean values of rooting with softwood stem cuttings, whatever hormone application and nursery type, could be explained by the presence of leaves. Generally, the rooting of stem cuttings depends on the physiological processes of the leaf such as photosynthesis and transpiration (Leakey and Storeton-West 1992;Oboho and Iyadi 2013;Takoutsing et al 2014). Rooting is maximized when the cutting is photosynthetically active and producing assimilates for the development and elongation of the root primordia (Hartmann et al 2002;George et al 2007;Leakey 2014a).…”

(2016). Propagation of Garcinia kola (Heckel) by stem and root cuttings. Silva Fennica vol. 50 no. 4 article id 1588. 17 p. http://dx.doi.org/10.14214/sf.1588. Highlights• Roots and branches cuttings from mature forest trees are difficult to sprout.• The highest mean numbers of roots and buds produced were obtained with softwood cuttings.• The aqueous IBA treatment was more effective than the powder in promoting rooting and root development.• Non-mist poly-propagator gave the best propagation results.• Seedling stockplants cut above node 1 promoted most vigorous shoots production. AbstractThe availability of appropriate propagation techniques is a major constraint to the domestication of the forest trees widely used by rural communities; such as Garcinia kola (Heckel). This study tested the ability of root and stem cuttings to regenerate vegetatively when treated with indole-3-butyric acid (IBA), and set in non-mist poly-propagator within a shaded nursery. It found that G. kola is amenable to propagation by softwood stem cuttings. Attention was given to the effect of cutting age (softwood, semi hardwood) and IBA application with regard to the sprouting and rooting efficiency. Bud and leaf emergence time were also investigated, as was the coppicing ability of the stump. Results revealed that roots and branches from mature forest trees did not sprout under any culture conditions. The highest percentages of rooting (70-85%) were obtained with softwood cuttings set in non-mist poly-propagator, regardless of hormonal treatment. The mean numbers of buds (2.9 ± 0.4) and roots (2.6 ± 0.1) produced by softwood cuttings was significantly greater than those obtained in the Control. The best average emergence time of buds (25.1 days ± 9.3) and leaves (36.8days ± 8.4) was obtained with cuttings treated with IBA and set in non-mist poly-propagator against, 54.4 ± 12.5 and 72.6 ± 3.4 days respectively for the Control. In general, non-mist poly-propagator gave the best propagation results. When coppiced, the shoots emerging from stumps with one node were the most vigorous.

“…The higher sprouting in middle and basal stem cuttings results in a greater number of apical shoots, which is closely related to the production of auxin [16,17]. Therefore, sprouting increases the proportion of auxin in relation to cytokinin, promoting induction of adventitious roots [18,19].…”

The herbaceous vine Tropaeolum pentaphyllum Lam. (Tropaeolaceae), popularly known as crem, has great potential for use, especially its tubers. However, there is still a lack of studies regarding this species. The objective of this study was to test the viability of propagation by stem cuttings for the production of T. pentaphyllum seed tubers. Two experiments were carried out in a greenhouse under controlled conditions. In both experiments, experimental design was completely randomized. In the first one, five treatments were evaluated (stem cuttings with 10, 15, 20, 25, and 30 cm) with three replicates, each one with 10 stem cuttings. In the second experiment, three treatments were evaluated (stem cuttings positions: apical, middle and basal), with four replications, each one with 10 stem cuttings. Data were submitted to analysis of variance (ANOVA) and the means were compared by Tukey’s test (p < 0.05). Stem cuttings with 15 cm length had the highest rate of tuber formation (20.0%) and produced tubers with highest mass (3.2 g). Cuttings from the middle portion of the stem had the highest rooting (52.5%) and tuber formation (45.0%) rates. Thus, cuttings with 15 cm length from the middle portion of the stem are indicated for propagation by cuttings of T. pentaphyllum. Considering the potential for the use of this species in the future, the results found in this study are very important, since the propagation by cuttings would enable the production of a large amount of seed tubers in a short period of time.

“…The rooting of cuttings from mature trees is generally recognized as being difficult, in contrast to that of juvenile cuttings. However, the good rooting of mature cuttings of G. kola and Annona muricata enabled them to be categorized as easy to root species, while Anonidum mannii, Gambeya albida and Irvingia gabonensis were rated moderately easy [367,368]. In contrast, Triplochiton scleroxylon, which is easy to propagate by juvenile cuttings [37], was difficult to propagate from mature cuttings [367].…”

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?
