•Butia capitata embryos were subjected to water stress (WS) and fast hydration (FH).•Protein reserves, SOD activity, and ABA biosynthesis are related to WS tolerance.•Biophysical damage to cell structure cause viability losses under severe WS.•Tolerance to WS and FH is crucial to the resilience of B...
