“…Many studies have shown that dipping cuttings in auxin solutions ranging from concentrations of 2.5 to 5 g l -1 or sprinkled with rooting powder stimulate the rhizogenesis of forest trees (Tchoundjeu et al 2002;Teklehaimanot et al 2004;Sanoussi et al 2012). Furthermore, the interaction between auxin and carbohydrates has been recognised as vital for root formation (Sorinet al 2005;Georges et al 2007).…”

“…In addition, vegetative propagation studies have investigated the grafting of juvenile seedlings (Yakubu et al 2014b), but there has been little work on the rooting of stem and root cuttings in this species. However, many other West African indigenous tree species producing AFTPs have been found to be easily propagated by leafy stem cuttings (Leakey 2014a):Vitex madiensis (Mapongmetsem 2006); Vitellaria paradoxa and Parkia biglobosa (Teklehaimanot 2004); Dacryodes edulis and Irvingia gabonensis (Shiembo et al1996); Vitex doniana (Achigan- Dako et al 2011) etc.…”

(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.

“…It is well known that one of the most marked environmental effects on shoot production and cutting success is season (light, temperature, moisture, fungus attack, etc.). Its effect has been shown for various plants (Rauter 1983;Monteuuis et al 1995;Teklehaimanot et al 2004;Bhardwaj and Mishra 2005;Danthu et al 2008). The improvement of CUT and RCUT during the second propagation period is due in part to the season effect, but is not the only cause of variation in shoot production and cutting success, other causes include environmental risks, physiological age, and a potential operator effect.…”

“…Influential factors affecting rooting ability can be divided into exogenous and endogenous, and are liable to interact. The season (i.e., combined effect of temperature, moisture, light availability…) is considered as the most influential exogenous factor affecting rooting ability (Rauter 1983;Monteuuis et al 1995;Teklehaimanot et al 2004;Danthu et al 2008). Endogenous factors include genetic identity (Shepherd et al 2005) and the physiological state of plant (Mankessi et al 2009).…”

To study the genetic determinism of propagation by cutting, 2,115 individuals of 83 full-sib families of the Eucalyptus urophylla×Eucalyptus grandis hybrid were used as stock plants and propagated by cuttings. Shoot production (PROD) and cutting success (CUT) were measured in two periods corresponding to the dry and rainy seasons. The experiments showed a significant effect of propagation period, suggesting the combined influence of environmental conditions and physiological state of stock plants. Using the linear mixed model (LMM) and the generalized one (GLMM) to take into account the non-normal distribution, the additive and dominance variances were estimated. They were significantly different from zero for PROD and CUT, as was the interaction between genetic effects and periods. The dominance variance was equal or higher than additive variance for both traits (1 < σ 2 D /σ 2 A < 1.5). Broad-and narrow-sense heritabilities change with the model type. For PROD, with LMM, they were moderate (h 2 ss =0.182 and H 2 sl =0.443) but high with GLMM (h 2 ss =0.431 and H 2 sl =0.891). For CUT, the same trend was observed for variances but the genetic control was weaker with heritabilities smaller than 0.3. The selection accuracy (r) was affected by the statistical model, r=0.94 and r=0.42 for PROD using LMM and GLMM, respectively. Genetic correlations between PROD, CUT, and the field growth of clones at 25 months were relatively low. These results are important elements to consider for breeding strategies that target genetic gain for both field growth and cutting success.

“…Les paramètres étudiés ont été classiquement : les substrats de bouturage, les traitements auxiniques exogènes (« hormones ») de la base des boutures, les ambiances de bouturage, à savoir sous confinement ou en plein air sous ombrière, et les effets saisonniers. Ces derniers, trop souvent sous-estimés (Monteuuis, 1985 ;Teklehaimanot et al, 2004), sont susceptibles d'influencer très fortement l'aptitude au bouturage du matériel végétal au moment de la récolte à partir de la tête de clone ou du pied-mère, puis tout au long de la phase d'enracinement dans les conditions du CRRFM.…”

L'arganier est un arbre à usages multiples de grand intérêt socio-économique pour le Sud-Ouest marocain. Il est utilisé pour l'alimentation des hommes et du bétail, en médecine, en cosmétique, tout en permettant de lutter contre la désertification et l'érosion en produisant du bois à diverses finalités. Les peuplements naturels, en constante diminution depuis le XIXe siècle, sont menacés par diverses pressions anthropiques, de plus en plus fortes, réduisant les capacités de régénération naturelle de l'espèce. Dans ce contexte, le Cirad a été sollicité en 2006 afin d'oeuvrer concrètement à la réhabilitation de l'arganeraie, sous la forme d'un projet financé pour une durée de trois ans. Le but de ce projet est d'améliorer, par la recherche appliquée, la qualité de l'arganeraie à travers la production d'arganiers de qualité supérieure issus d'individus sélectionnés. Ceux-ci seront multipliés en masse au moyen des techniques de clonage les plus adaptées, en tirant profit pour les sélections de la grande variabilité existant entre les plants issus de graines, pour produire des populations clonales plus homogènes. Après deux ans de collaboration avec le Centre Régional de Recherche Forestière de Marrakech et l'Université de Marrakech, plus d'un millier de boutures de jeunes arganiers ont pu être produites dans le cadre d'essais de mise au point de la technique de bouturage de l'espèce. Ce matériel sera utilisé comme pieds-mères expérimentaux et pour des tests de comportement au champ, en comparaison à des semis traditionnels. Par ailleurs, sur les quatorze têtes de clones sélectionnées par les populations locales, huit ont pu être mobilisées pour amorcer la propagation en masse par bouturage, avant les tests au champ. Les techniques de multiplication végétative développées pourront également être mises à profit pour la production en quantité de plants à partir des semis issus des fruits récoltés sur les têtes de clones précitées, présumées de qualité supérieure.
