“…This difference was even perceptible within the same species such as D. microcarpum that had plantlets from all the regeneration mechanisms. At the earlier stage, coppices might grow faster than seedling sprouts and true seedlings and reach sapling stage as shown by several studies (Chidumayo and Frost, 1996;Hoffmann, 1998;Miller and Kauffman, 1998;Bellefontaine et al, 2000;Silla et al, 2002;Winkler and Fischer, 2002;Luoga et al, 2004). The larger root system of coppice would offer more surface area for water and nutrient uptake and allow more vigorous resprouting, hence rendering the plant less dependent on external resources (Cruz et al, 2002;Kennard et al, 2002).…”

“…Des travaux de certains auteurs comme Palik et al (2003), Prévost et Pothier (2003) ont permis de montrer chez P. tremuloides et P. grandidentata, des espèces des forêts du nord de l'Amérique, que les formes d'éclaircie de couvert ligneux influencent la régénérescence de la composante ligneuse. D'autres études encore, Silla et al (2002) ont permis de montrer qu'une couverture ligneuse inférieure à 40% favorise la régénération par graines chez Fitzroya cupressoides, une espèce chilienne qui se régénère à la fois par graines, par drageons et par marcottes terrestres.…”

Résumé.-Une étude de la régénération naturelle d'Isoberlinia doka Craib & Stapf et I. tomentosa (Harms) Craib & Stapf a été réalisée en zone soudanienne au Togo sur 74 placettes de 10 m x 10 m. Elle a permis de montrer que les deux espèces assurent leur pérennité à la fois par voie sexuée et asexuée. Sur l'ensemble des cinq sites étudiés (champs, jachères < 5 ans, jachères de 5 à 10 ans, jachères >11 ans, forêts), on observe en moyenne 32% de régénération par semis, 10,6% par rejets de souche et 57,4% par drageons. Dans les champs et les jeunes jachères, le drageonnage est le principal mode de régénération. Les drageons et les semis naturels favoriseraient beaucoup plus la reconstitution des forêts à Isoberlinia que les rejets de souches. La faculté de la plante à drageonner peut être exploitée sans engendrer de grands frais pour la restauration des peuplements, surtout dans les zones à stress hydrique élevé.Mots clés : Isoberlinia -régénération naturelle -drageonnage -semis -rejetsTogo. Abstract.-Isoberlinia doka Craib & Stapf and I. tomentosa (Harms) Craib &Stapf natural regeneration is studied in the Sudanian zone of Togo on 74 plots (10 m x10 m). The survey show that both species self-maintain by seedlings (32%), stump resprouts (10.6%) and root suckers (57.4%) in five types habitat (fields, fallows less than 5 years, fallows from 5 to 10 years, fallows more than 11 years ,forests). Suckering is the most important in fields and fallows. Root suckers and seedlings are more prone to regenerate the Isoberlinia woodlands than stump resprouts. Suckering is a low cost effective way to restore Isoberlinia forests especially in dry areas.

“…By contrast, the stands in our study were completely protected after logging, and all stumps remained in the stands. Stump sprouts have long been considered as important natural recruits in disturbed forests because of their abundant number and rapid growth (Gardiner and Helmig, 1997;Hoffmann, 1998;Miller and Kauffman, 1998;Silla et al, 2002;Luoga et al, 2004;Lockhart and Chambers, 2007). However, the production of stump sprouts depends on the formation of stumps, which are affected by disturbances, such as logging, naturally fallen trees, animal injury, and fire.…”

Aim of study: Quercus variabilis (Chinese cork oak) reproduces asexually and sexually. This study aimed to determine the status and growth of asexual and sexual recruits of Q. variabilis in different forest recovery stages.Area of study: Three selective logged stands and one unlogged stand in Q. variabilis forest, Shaanxi Province, China. Material and methods:Origin, number, basal diameter, height and size structure of Q. variabilis shoots (height ≤200 cm) were investigated in the plots of 5, 10, and 20-years post-logging stands and unlogged stand. Effects of recovery stage on the density and growth of the three original recruits (stump sprouts, stem base sprouts and true seedlings) were analysis by One-way ANOVA.Main results: Sprouts dominated logged stands, whereas true seedlings dominated unlogged stand, stem base sprouts only existed in 20-years post-logging and unlogged stands. Stump sprout density and sprout number per stump both declined with extended post-logging time. True seedlings density increased from 7 to 20 shoots/100 m 2 as the postlogging time extended, and peaked in unlogged stand (94 shoots/100 m 2 ). An ongoing size structure was observed in true seedlings in all stands. Stump sprouts were taller and greater than true seedlings.Research highlights: Stump sprouts contributed more to Q. variabilis forest recovery in the early stage after disturbance. The contribution of true seedlings was limited in the same stage, but they were beneficial for population long-term development. Stem base sprouts were most likely to be a survival strategy rather than a reproductive strategy.
