“…The results obtained for the rooting of leafy stem cuttings of G. lucida (50%) are not as strong as those previously obtained by other authors on other West African indigenous fruit species. For example, Mialoundama et al (2002) There is clearly a need to improve the rooting success in stem cuttings. Our results suggest that G. lucida cuttings respond to auxins, and that both leaf area and rooting medium are important factors that should be optimized.…”

Garcinia lucida Vesque (Clusiaceae) is a tree species that is highly valued for its medicinal properties by rural households in the humid forest zone of Cameroon. However, the unsustainable exploitation of the species threatens its long-term regeneration. This study focuses on its vegetative propagation via stem cuttings in non-mist propagators and through grafting. The study tests the effects of three rooting media (sand, sawdust, sand + sawdust (1/1); three leaf sizes (0,25 and 50 cm 2 ); and three types of hormone [indole butyric acid (IBA), indole-3-acetic acid (IAA) and naphthalene acetic acid (NAA)], applied as a single dose. Furthermore, three grafting techniques (cleft, side tongue and whip-and-tongue grafting) were tested. All experiments were designed as completely randomized blocks with three replicates. Results showed that cuttings require a medium that has low water holding capacity and high porosity, and a leaf area of 50 cm 2 and NAA treatment; grafting success was affected by the technique used, with top cleft grafting yielding a 100% success rate. From this preliminary study, it is concluded that G. lucida is amenable to vegetative propagation by cuttings and grafting.

“…It is highly valued for its fruits (Mialoundama et al 2002) in the humid zones of West and Central Africa. Vegetative methods of propagation through leafy stem cuttings and marcotting have been developed and used successfully (Mampouya et al 1994;Kengue and Tchio 1994;Mialoundama et al 2002). Vegetative propagules are increasingly becoming more attractive to users due to the added advantage of capturing desirable traits, quicker fruit yields and their potential in resolving problems of seasonality in D. edulis fruit production (Simon et al 2008).…”

Root morphology of 5-year-old trees of Dacryodes edulis (G. Don) H. J. Lam of seed and two vegetative (cutting and marcot) origins were assessed in Cameroon. Roots of D. edulis trees of seed and vegetative origins were totally excavated and their root morphology described and quantified. Trees of seed origin were characterized by a tap root, reaching depths of about 1.2 m. Contrarily trees of cutting origin showed three strong vertical roots (d [ 5 mm) with the longest reaching depths of 1.31 m. Trees of marcot origin were observed to have thick, relatively short prominent vertical roots, reaching depths of 1.15 m. At fixed lateral intra-row distances of 50 cm from tree bases, trees of seed and marcot origins recorded high root densities at soil depths of 0-20 cm; both differed significantly (p = 0.032) from those of trees of cutting origin. At soil depth of 60-100 cm, trees of cutting origin recorded the highest root density which however differ significantly (p = 0.016) from those of trees of both seed and marcot origins. D. edulis trees of seed origin had a tap root system, whereas trees of vegetative origin (cuttings and marcots) had developed prominent main adventitious roots growing vertically (sinker roots), into greater depths and a wider/deeper lateral root spread than seedlings. This could be a vital adaptation to the absence of a genetically determined tap roots in trees of vegetative origins so as not to compromise the acquisition of soil-based resources (water and dissolved ions) and anchorage.

“…In addition, nut grafting process involving the removal of the hypocotyls and root from a germinated nut followed by inserting of the scion into a slit cut into the nut as reported in some forest trees (Jaynes and Messner, 1967) is yet to be investigated. Vegetative propagation by marcotting has yielded very excellent results from experiments using different branch types, branch diameter, substrate and hormone concentrations (Mialoundama et al, 2002). Many marcots from ICRAF plus-trees have been planted on farm and in comparison, a stand of seedlings and marcots from five families in Mbalmayo.…”

“…There has been a transition in vegetative propagation by cutting, from a very difficult to root species in the 50ths (Philippe, 1957) to about 100% success in rooting of young seedlings with the development of new techniques of propagation. The published report by Mialoundama et al (2002) Mbeuyo et al (2013) and many investigations still need to be done on the effect of clones on rooting, use of mycorrhiza to improve rooting ability, source of rooting materials from the tree, etc. In addition, nut grafting process involving the removal of the hypocotyls and root from a germinated nut followed by inserting of the scion into a slit cut into the nut as reported in some forest trees (Jaynes and Messner, 1967) is yet to be investigated.…”
