A syndrome called "Kiwifruit Decline Syndrome" (KiDS) affects kiwifruit in several Mediterranean areas, causing growth arrest and wilt that rapidly progress to desiccation, scarce root growth, absence of fibrous roots, brown soft-rotting cortical detachment from the central cylinder. The origin is considered multifactorial, a correlation with hydraulic conductance impairment caused by high vapor pressure deficit (VPD) temperature was detected. In this work, over-tree micro-sprinkler irrigation shading nets were tested protect leaves overheating locally decrease VPD. Leaf gas exchanges, leaf temperature, stem water potential, starch content, xylem vessel diameter, density, vulnerability cavitation assessed. positive effect associated observed: lower higher stomatal conductance, photosynthesis detected; moreover, content summer. Narrow diameters observed, indicating long-term adaptation rising VPD for cavitation, all plants, but index indicated plant stress under shading. These results indicate microclimate control proper agronomic management can climate stress, decreasing risk KiDS onset.

The decline of perennial plant species, including oak, olive, and kiwifruit, is a phenomenon currently observed in many areas the world. In this review, such species are chosen precisely because, despite differences their botany, native distribution, current utilization, they all affected by significant global or local declines. An analysis main common causes involved could be useful for better understanding phenomenon. Quercus impacted “Chronic Oak Decline” (COD), “Sudden (SOD), “Acute (AOD). Italy, olive groves severely damaged “Olive Quick Decline Syndrome”, whereas kiwifruit orchards struck “Kiwifruit Vine Syndrome” (KVDS). Among abiotic inciting stressors, drought, warmer temperatures, waterlogging, within climate change scenario, declines described herein as well dysbiosis. involvement some aggressive phytopathogens another feature these Oomycetes contribute to COD, SOD, KVDS; Xylella fastidiosa subsp. pauca Botryosphaeriaceae affect enterobacteria AOD, representing decisive contributing factors. These quite complex, comprehensive approach required dissect facets involved. A altered host–microbial community relationships can lead more tailored managing Maintaining tree resilience Earth remains primary goal achieve preserving both natural ecosystems profitable crops.
