TL;DR
This study shows that a hydrogel polymer helps colored cotton plants maintain health and antioxidant activity under water scarcity.
Contribution
The study demonstrates the residual benefits of hydrogel polymer application on cotton physiology under water deficit.
Findings
Water restriction reduced plant health metrics like relative water content and gas exchange.
Hydrogel polymer improved physiological parameters and antioxidant activity in cotton cultivars.
Residual polymer effects continued to benefit plants in subsequent growth cycles.
Abstract
The objective of this study was to evaluate the effects of hydrogel polymer application on the antioxidant activity and physiological performance of colored-fiber cotton cultivars grown under different levels of water restriction. Two experiments were conducted under greenhouse conditions. In the first experiment, the effects of the hydrogel polymer, cultivars, and irrigation replacement levels were evaluated; in the second, the residual effect of the hydrogel polymer applied in the first experiment was assessed using the same cultivars and irrigation depths. Water restriction negatively affected relative water content, gas exchange, chlorophyll a fluorescence, and antioxidant activity, and increased electrolyte leakage in cotton cultivars. Water deficit reduced relative water content, gas exchange, chlorophyll a fluorescence, and antioxidant activity, while increasing electrolyte…
