The objective of this study was to identify physiological traits that could distinguish between cotton genotypes that were tolerant or sensitive to water deficits.
The experiment was conducted in a completely randomized design through a factorial combination to analyze four genotypes (BRS 187 8H and ACALA SJ-4 - water deficit tolerant; CNPA 7H and SU-0450-8909 - water deficit sensitive) and two water regimes (watered-always irrigated and stressed-with a water deficit imposed at flowering).
Irrigation was suspended for the plant...
