“…There are no correlation between soil type and sprouting capacity. The stumps with the youngest produced (one year old) produced 18-37 sprouts per living stump (range 2-68) while stumps with 7 years old sprouts had 3 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) …”

We investigated the sprouting capacity of poplar stumps in ten 8–21-year old stands growing on former farmland in Sweden situated between 55°N and 60°N. Seven of the stands were planted with the clone OP-42 (Populus maximowiczii Henry × Populus trichocarpa Torr. and Gray), one with black cottonwood (Populus trichocarpa Torr. and Gray) and two with unidentified clones. The poplars’ mean age was 17 years (range 8–21); six of the stands were growing on clay soils, two on tills and two on loam. The studied sprouts were 1–7 years old. Stump sprouting was observed in all studied stands. The number of sprouts per living stump decreased as sprout age increased. The mean dry mass of all sprouts stump−1 was 16.1 ± 14.0 (range 3.3–37.2) kg. A biomass equation was constructed for estimating sprout biomass from the sprouts’ diameter at 10 cm above the ground (D10). The mean total sprout weight per hectare for sprouts amounted to 16.9 ± 14.6 (range 1.2–41.3) tons ha−1 when calculated for the actual living stumps in the studied areas.

“…Coppicing has been widely adopted as a management technique for biomass production because the early growth rate of sprouts is greater than that of seedlings or cuttings [11,12]. Sprouts develop from dormant buds, which are released following hormonal suppression when a tree is cut [13,14].…”

Summary — In order to study the effects of extremely short rotations, the growth of hybrid poplar cuttings coppiced biannually over a period of 4 years, in summer and in winter, was compared with growth of cuttings coppiced annually in winter. The biannual treatment led to a progressive decrease in height growth and in total biomass production, and to high stool mortality. Some aspects of the physiology of coppicing are discussed.growth / coppice / short rotation / Populus Résumé — Production de biomasse et mortalité des souches de peuplier hybride recépé deux fois par an. Des boutures de peuplier hybride interaméricain recépées deux fois par an pendant 4 ans ont été comparées à des boutures recépées annuellement, dans le but d'étudier les effets d'un stress physiologique important sur la croissance des rejets de taillis. Le recépage bisannuel a entraîné une forte mortalité des souches et une baisse de la croissance en hauteur. Une diminution de la production de biomasse sèche par unité de surface peut être attribuée à la fois à une baisse de production en biomasse des souches vivantes et à la mortalité. Différents aspects du fonctionnement des arbres traités en taillis sont discutés.
