AI Article Synopsis
- The study assessed how seed treatment and silicon application affected lettuce plants under different salinity levels.
- Results showed that salinity significantly harmed plant health, as indicated by reduced leaf number, head weight, and chlorophyll levels.
- However, applying silicon improved various growth metrics and reduced oxidative stress markers, indicating a protective effect against salinity stress.
Article Abstract
We investigated the impact of as seed treatment and application with silicon on lettuce plants exposed to salinity levels (4 dS m and 8 dS m). Results revealed that leaves number, head weight, total yield, relative water content (RWC), and chlorophyll a and b declined considerably due to two salinity levels. Oxidative stress markers, i.e., hydrogen peroxide (HO), superoxide (O), and lipid peroxidation (MDA) dramatically augmented in stressed plants. On the other hand, leaves number, total yield, RWC, and chlorophyll a, b in stressed lettuce plants were considerably enhanced because of the application of Si or In contrast, EL%, MDA, and HO were considerably reduced in treated lettuce plants with Si and . In addition, the treatment with Si and increased head weight (g) and total yield (ton hectare-1), and caused up-regulation of proline and catalase, superoxide dismutase, peroxidase, and polyphenol oxidase activity in lettuce leaves under salinity conditions.
