“…In addition, it is noted that plants irrigated with water volume equivalent to 80% of evapotranspiration already presented reduced variables. Studies have associated greater drought tolerance in trees with low growth rates (Rose et al, 2009;Taeger et al, 2013. ).…”

The objective of the present study was to evaluate the initial growth of Khaya senegalensis plants under water deficit. The work was carried out at Ipameri, Goiás on a bench in full sun following the completely randomized experimental design with six treatments and six replications. 120-day-old mahogany plants (Khaya senegalensis) grown in eight-liter pots were subjected to six treatments for 12 days (plants irrigated daily with 100, 80, 60, 40, 20 and 0% of evapotranspiration) with six replications. At 132 days after emergence, the plants were assessed for: plant height, stem diameter, number of leaves, foliar area, daily transpiration, relative water content, total chlorophylls and carotenoids, leaf, stem and root mass ratios, and total biomass. The data were submitted to F-test and, when significant, to regression test at 5% probability. High stomatal control, reduced transpiration, low leaf concentration of total chlorophylls and increased root system growth to the detriment of the shoot growth indicate that Khaya senegalensis is tolerant to moderate water deficit.

Climatic change exposes temperate trees to the simultaneous alteration of various growth-relevant factors, among them increased temperatures, extended growing season length and rising atmospheric [CO 2 ], often in combination with more severe droughts and reduced air humidities in summer, and elevated atmospheric N deposition. We conducted a multi-factorial climate chamber experiment to search for interactive effects of temperature (T), soil moisture (h), water vapour saturation deficit (VPD) and N availability (N) on the growth of Fagus sylvatica saplings and for identifying the most relevant factors that control leaf area development and productivity under a future warmer and drier climate with continuing high N deposition. For each of the four factors, two levels were simulated, reflecting current and expected future conditions in Central European beech forests. All four factors (including VPD) had a significant effect on productivity; several factors (e.g. T 9 VPD) interacted in a synergistic way. Productivity was most tightly correlated with the number of leaves while leaf area was less influential and photosynthetic activity was of only minor importance. The number of leaves produced was most tightly correlated with h, N and VPD, while leaf area (leaf expansion) showed closest relation to temperature. We conclude that predictions about the growth response of trees to climate change and altered atmospheric N deposition need to consider a multitude of environmental factors and must account for positive and negative factor interactions.

I soprassuoli forestali governati a ceduo rappresentano una parte consistente dei boschi italiani. Al fine di una gestione efficace dal punto di vista ambientale ed economico-finanziario è opportuna una conoscenza approfondita delle specifiche caratteristiche di questo sistema selvicolturale. Questa nota si propone di offrire un aggiornamento e una sintesi degli aspetti più rilevanti di produttività e gestione dei principali tipi di ceduo in Italia, attraverso l'analisi dei principali contributi disponibili in merito nella letteratura specializzata. Viene messa in evidenza la necessità di razionalizzare la gestione selvicolturale, dedicando maggiori sforzi al miglioramento della funzionalità del ceduo, legando gli aspetti produttivi con quelli ambientali e paesaggistici.Parole chiave: gestione forestale; selvicoltura; produzione legnosa. Key words: forest management; silvicultural system; wood production.
