Water Potential Isotherms Reveal Different but Coordinated Responses at Leaf and Root Levels Under Controlled Drought

Patrizia Trifilò, Francesco Petruzzellis, Daniele Torre, Stefano Mileto et autres

ABSTRACT Understanding how leaves and roots modulate their water relations under drought is critical for predicting plant stress resistance/resilience. We compared water relations traits derived on water potential isotherms in 10 young woody and herbaceous species grown under the same soil and …

Differential Cadmium Responses in Two Salvia Species: Implications for Tolerance and Ecotoxicity

Douaa Bekkai, Natalizia Miceli, Francesco Cimino, Carmelo Coppolino et autres

Heavy metal contamination poses critical challenges for the cultivation of medicinal plants. This study explores cadmium (Cd)-induced morpho-physiological and metabolic responses in Salvia officinalis (So) and the rare endemic Salvia ceratophylloides (Sc). Plants were exposed to cadmium contamination corresponding to 5 and …

Citrate Coated Maghemite Nanoparticles for Sustainable Nano-fertilization

Vanna Torrisi, Vincenzina Strano, Giuseppe Granata, Libera Vitiello et autres

High concentration of water colloidal solution based on maghemite$\text{Fe}2\mathrm{O}_{3}$nanoparticles (NPs) was optimized for sustainable fertilization. Citrate surface functionalization method was carried out, together with size and morphological characterization of functionalized NPs and the investigation of total metal amount in the solution. Stability …
