Abstract

An adequate description and prediction of plant development is critical for understanding plant growth and its responses to the environment. Only then we can assess the impact of a changing environment on plant productivity and survival, understand plant adaptation, design adequate agricultural production systems, and optimize natural resources management. Of particular importance for water resource management are the effects of plant ontogeny on plant water use and productivity throughout the regulation of leaf area. This determines the patterns of plant water demand and the partitioning between transpiration and evaporation components. Therefore, plant development dictates the selection of cultivars that best fit the water availability patterns under dryland conditions, and the amount, frequency and timing for irrigation otherwise.

Italian cinema and the contested memories of fascism: Notes towards a historical reconsideration

“…Trampling over protocol, which accords RAI at least the illusion of political autonomy, Gasparri issued invitations in his name to a RAI premiere of the film, to be hosted in the same Roman venue where AN were celebrating their tenth anniversary with some pomp. Then, faced with a loyal audience of comrades and the film's embarrassed cast and crew, Gasparri regaled them with an impromptu stinging attack on historians guilty of downplaying the foibe (Fusani, 2005;Messina, 2005).…”
