Capacity of a high resolution hydroclimatic modelling chair to simulate soil water deficit indexes for Douglas-fir and common Beeches over Burgundy
2016
During the 2003 drought and heat wave event, douglas-fir and common beech stands in Burgundy have been heavily affected, and presented symptoms of dieback and mortality. This event seems to be the first occurrence of expected climatic changes in the near future and questions their sustainability in Burgundy since their climate vulnerability is mainly due to the amplitude and accumulated water constraints exercised during their growing cycle. In the context of climate change and in order to provide information to forest managers who partly rely on a mapping of the climatic constraints until the end of this century, this work explores the ability of a high resolution hydroclimatic modelling c…
Productive and vegetative responses of 'Gala' and 'Fuji' apple trees under controlled irrigation strategies
2008
We investigated the productive and vegetative responses of ‘Gala’ and 'Fuji' apple (Malus domestica Borkh.) trees to deficit irrigation and partial rootzone drying under the dry climate of central Sicily. Soil water tension (SWT), stomatal conductance, yield, fruit quality, fruit growth, and shoot extension of conventionally irrigated trees (CI), where drip emitters on both sides of each tree were left open, were compared to that of partial rootzone drying (PRD) trees, where only one side of the rootzone was irrigated for the entire season (receiving 50% of the CI irrigation water), and to that of deficit irrigated (DI) trees, where drip emitters on both sides of the rootzone were deliverin…
