Climate change, which has been an important issue in recent decades, is causing an increase in the frequency and intensity of drought events, putting many agricultural crops at risk, including the common walnut (Juglans regia). This thesis examines the effects of water stress on kernel development, evaluating it’s impact on both the qualitative and quantitative characteristics of production. The main physiological processes involved in kernel formation are described, focusing on lipid metabolism and the accumulation of nutrients, which contribute to the kernel’s well-known nutritional properties. Some of the most recent studies applying water stress and regulated deficit irrigation techniques will be analyzed, with a focus on the morphological and physiological responses of the walnut tree to these conditions. The results reviewed highlight the importance of sustainable irrigation management, with special attention to the plant’s phenological stages.
Il cambiamento climatico protagonista degli ultimi decenni sta determinando un aumento della frequenza e dell’intensità degli eventi di siccità, mettendo a rischio molte colture agrarie, tra queste il noce comune (Juglans regia). Questa tesi analizza gli effetti dello stress idrico sullo sviluppo del gheriglio, valutando il suo impatto sulle caratteristiche qualitative e quantitative della produzione. Vengono descritti i principali processi fisiologici che caratterizzano la formazione del gheriglio, in particolare il metabolismo lipidico e l’accumulo di sostanze nutritive, che rendono il gheriglio conosciuto per le sue proprietà nutrizionali. Verranno analizzati alcuni degli studi più recenti in cui vengono applicate le tecniche di stress idrico e irrigazione controllata ed approfondite le risposte morfologiche e fisiologiche del noce a questi eventi. I risultati analizzati confermano l’importanza di una gestione irrigua sostenibile e mirata all’attenzione verso le fasi fenologiche della pianta.

Abstract
Climate change, which has been an important issue in recent decades, is causing an increase in the frequency and intensity of drought events, putting many agricultural crops at risk, including the common walnut (Juglans regia). This thesis examines the effects of water stress on kernel development, evaluating it’s impact on both the qualitative and quantitative characteristics of production. The main physiological processes involved in kernel formation are described, focusing on lipid metabolism and the accumulation of nutrients, which contribute to the kernel’s well-known nutritional properties. Some of the most recent studies applying water stress and regulated deficit irrigation techniques will be analyzed, with a focus on the morphological and physiological responses of the walnut tree to these conditions. The results reviewed highlight the importance of sustainable irrigation management, with special attention to the plant’s phenological stages.| File | Dimensione | Formato | |
