Hormetic Response of Photosystem II Function Induced by Nontoxic Calcium Hydroxide Nanoparticles.

ABSTRACT: In recent years, inorganic nanoparticles, including calcium hydroxide nanoparticles [Ca Ca(OH)₂ NPs], have attracted significant interest for their ability to impact plant photosynthesis and boost agricultural productivity. In this study, the effects of 15 and 30 mg L^-1 oleylamine-coated calcium hydroxide nanoparticles [Ca(OH)₂@OAm NPs] on photosystem II (PSII) photochemistry were investigated on tomato plants at their growth irradiance (GI) (580 μmol photons m^-2 s^-1) and at high irradiance (HI) (1000 μmol photons m^-2 s^-1). Ca(OH)₂@OAm NPs synthesized via a microwave-assisted method revealed a crystallite size of 25 nm with 34% w/w of oleylamine coater, a hydrodynamic size of 145 nm, and a ζ-potential o
