Nanosized zinc oxide (n-ZnO) particles pretreatment to alfalfa seedlings alleviate heat-induced morpho-physiological and ultrastructural damages

Popis výsledku v původním jazyce

Global efforts are in rapid progress to tackle the emerging conundrum of climate change-induced heat stress in grassland ecosystems. Zinc oxide nanoparticles (n ZnO) are known to play a crucial role in plants abiotic stress regulation, but its response in alfalfa against heat stress has not been explored. This study aimed at assessing the effects of n ZnO on alfalfa under heat stress by various morpho physiological and cellular approaches. Five week old alfalfa seedlings were subjected to foliar application of n ZnO as a pretreatment before the onset of heat stress (BHS) to evaluate its effect on heat tolerance, and as a post-treatment after heat stress (AHS) to evaluate recovery efficiency. In vitro studies on Zn release from n ZnO by Inductively coupled plasma mass spectroscopy (ICPMS) disclosed that the particle uptake and Zn release were concentration dependent. The uptake and translocation of n ZnO examined by transmission electron microscope (TEM) reveling showed that n-ZnO was primarily locali
