Growth, water relations and solute accumulation in osmotically stressed seedlings of the tropical tree Colophospermum mopane.
Root and hypocotyl elongation, water status and solute accumulation were studied in osmotically stressed seedlings of the tropical tree, Colophospermum mopane (Kirk ex Benth.) Kirk ex J. Léonard, which grows in hot arid areas of southern and central Africa. Seeds were imbibed for 24 h and then subjected to a polyethylene-glycol-generated osmotic stress of -0.03 (control), -0.2, -0.8, -1.6 or -2...
متن کاملGabonius gen. nov. (Leguminosae, Caesalpinioideae, Detarieae), a distant cousin of Hymenostegia endemic to Gabon
A new genus, Gabonius is described to accommodate a single species, Gabonius ngouniensis which was previously misplaced in Hymenostegia sensu lato. Gabonius ngouniensis is a widespread Gabonese endemic of evergreen forest. We assess G. ngouniensis as Least Concern (LC) according to IUCN criteria. A distribution map of Gabonius is presented, as is a table comparing the morphology of Gabonius, th...
متن کاملCharacterization of the Primary Metabolome of Brachystegia boehmii and Colophospermum mopane under Different Fire Regimes in Miombo and Mopane African Woodlands
Miombo and Mopane are ecological and economic important woodlands from Africa, highly affected by a combination of climate change factors, and anthropogenic fires. Although most species of these ecosystems are fire tolerant, the mechanisms that lead to adaptive responses (metabolic reconfiguration) are unknown. In this context, the aim of this study was to characterize the primary metabolite co...
متن کاملGrowth form and seasonal variation in leaf gas exchange of Colophospermum mopane savanna trees in northwest Botswana.
We investigated differences in physiological and morphological traits between the tall and short forms of mopane (Colophospermum mopane (Kirk ex Benth.) Kirk ex J. Léonard) trees growing near Maun, Botswana on a Kalahari sandveld overlying an impermeable calcrete duricrust. We sought to determine if differences between the two physiognomic types are attributable to the way they exploit availabl...
