“…Our results were similar to those described in Fraxinus americana [8], Acer saccharum [4], Liquidambar styraciflua [12], Betula pubescens [11] and in Euptelea polyandra [15]. In Q. petraea, epicormic buds were all of proventitious origin; they were primary or secondary: primary when they consisted of primary axillary buds which did not develop into branches and secondary, when they were produced by a primary axillary bud after its development or its death.…”

Evolution of the epicormic potential on 17-year-old Quercus petraea trees: first results

et al. 2001

-The epicormic potential was represented by the number of visible epicormic buds (primary and secondary) present at a given time and on a given length of stem. Data were collected from sixty-six 4-year-old annual shoots on 17-year-old Quercus petraea with 3 stand densities. We estimated the epicormic potential in 1997 and then followed its evolution over the next 2 years. Preliminary results showed that the epicormic potential decreased from 1997 to 1999, independently to the stand density. The loss of epicormic buds (death or development into shoots) was not compensated by the production of new epicormic buds. Furthermore, we report that the composition of the epicormic potential was unchanged for these 2 years: one third were primary epicormic buds and two thirds were secondary epicormic buds. Secondary epicormic buds were mainly found as individual and located at the base of branches. No formations of large clusters of epicormic buds were observed.Quercus petraea / epicormic potential / bud / shoot / estimation / evolution Résumé -Évolution du potentiel épicormique sur des chênes sessiles âgés de 17 ans : premiers résultats. Le potentiel épicormique est représenté par le nombre de bourgeons épicormiques visibles (primaires et secondaires) présents à un moment donné sur une unité de longueur définie. Les données ont été collectées sur la pousse annuelle âgée de 4 ans de 66 chênes sessiles âgés de 17 ans répartis dans 3 densités de culture. Nous avons évalué le potentiel épicormique en 1997 puis nous avons suivi son évolution les 2 années suivantes. Les premiers résultats ont montré que le potentiel épicormique a diminué de 1997 à 1999, indépendamment des densités de culture. La perte de bourgeons épicormiques (mort ou développement en gourmands) n'a pas été compensée par la formation de nouveaux bourgeons épi-cormiques. De plus, nous avons constaté que la composition du potentiel épicormique restait inchangée au cours de ces 2 années et comprenait toujours un tiers de bourgeons épicormiques primaires et deux tiers de bourgeons épicormiques secondaires. Ces derniers étaient essentiellement isolés et localisés à la base des branches. Aucune formation de groupes de bourgeons n'a été observée.Quercus petraea / potentiel épicormique / bourgeon / pousse / évaluation / évolution Ann. For.

“…In one case in the stand Rdi 0, a secondary bud of a cluster gave rise to an epicormic shoot. We never observed the formation of a cluster from a secondary bud belonging to a cluster, thus leading to a large cluster of epicormic buds as described by Kauppi et al [11].…”

“…Epicormic shoots, sometimes called reiterates (Barthélémy and Caraglio, 2007), have been the most studied epicormics in both angiosperms (Colin et al, 2008;Fontaine et al, 2004;Nicolini et al, 2001;Spiecker, 1991) and gymnosperms (Bryan and Lanner, 1981;Edelin, 1977;Ishii et al, 2002;O'Hara and Berrill, 2009), in temperate (Del Tredici, 2001;Fink, 1980;Spiecker, 1991;Nicolini et al, 2001) as well as in tropical regions (Ashton et al, 1990;Fink, 1983;Nicolini et al, 2003).

Epicormic ontogeny on Quercus petraea trunks and thinning effects quantified with the epicormic composition

Abstract• Effects of thinning on epicormics have rarely been demonstrated especially due to inaccurate surveying methods.• Our objective was to assess the effect of contrasted thinnings on the ontogeny of epicormics on sessile oak. We used the epicormic composition defined as the arrangement of epicormics in different classes (isolated bud, clustered buds, short and long shoots and "picots") and quantified by the total frequency of epicormics and the proportion of each class.• Epicormic composition was recorded in a silvicultural experiment testing highly contrasted thinnings, at 3 different stand stages and on lower (0.5-3 m) and upper (3-6 m) boles. Ageing provoked an accumulation of bud clusters and of picots. After thinning, epicormic shoots emerged mainly from (1) still present short epicormic shoots, (2) buds either isolated or in clusters depending on the stand stage. Upper boles bore epicormic compositions close to those observed on lower boles in the few preceding years. Upper logs were more reactive than lower boles.• To conclude, the epicormic composition was a relevant tool to follow the dynamics of the epicormic ontogeny and to demonstrate the effects of thinning on it.

“…Both types of regeneration result in fastwww.intechopen.com growing individual stems. In studies of dormant buds on birch, most have been found close to the ground: 0-10 cm above or 0-5 cm below ground level (Kauppi, 1989;Kauppi et al, 1987;Johansson, 1992a. The number of sprouts per living birch stump has been found to vary between 1 and 52, mean 10±8, decreasing to 3-8 sprouts per stump after five years (Johansson, 1992 b, c).…”
