Drought stress effects on quality and grain composition in four hybrid maize varieties with different stomatal resistance

Abstract

Objective: This study aimed to evaluate transpiration and its effects on grain quality in some maize hybrids under drought stress conditions. Material and Methods: The experiment was conducted using three irrigation levels-60 mm (control), 90 mm (moderate drought stress), and 120 mm (severe drought stress) of evaporation from a class A pan-applied to four maize hybrids: KSC 703, KSC 704, KSC 705, and KSC 706. This study was set up with three replications, carried out at Seed and Plant Improvement Institute (SPII), Karaj, Iran during 2015 and 2016 growing seasons. Results: The results indicated that under drought stress conditions, the levels of crude fiber and ash increased, while starch content decreased. The KSC 706 hybrid exhibited the lowest stomatal resistance and canopy temperature, and the highest grain starch content, averaging 64.84%. These findings suggest that increased stomatal opening and transpiration are associated with improved maize grain quality. Conclusion: Based on the findings, in regions where irrigation water is available and a higher starch content in grain is a priority, the KSC 706 hybrid is recommended.
