Calcium particle film shields sweet potato plants from abiotic stress

Abstract

Abiotic stresses can cause significant harm to economically important crops, making it essential to adopt sustainable methods to mitigate their negative effects. One promising approach is particle film technology, which has been shown to alleviate the impact of water scarcity and solar radiation on crops. In this study, our goal was to determine the action of particle film used in leaves of Ipomoea batatas L. grown under varying water conditions. Our findings indicate that plants treated with the particle film suffered less harm to their photosynthetic systems, particularly during the reproductive stadium, regardless of the water regime. Furthermore, the exogenous application of the particle film resulted in increased photosynthetic efficiency and electron transport rates in plants, as well as a decrease in the chl a/b ratio and expression of the Cdc2a gene. These results demonstrate that particle film technology has the potential to enhance crop resilience and productivity in sweet potatoes, even in adverse conditions.
