Overview

Analysis demonstrates high germination rates and antioxidant activity in tropical Alfalfa varieties under drought stress, suggesting potential for breeding.

Key Points

  • The research aims to evaluate the effect of drought stress on germination indices and antioxidant responses in tropical Alfalfa varieties.
  • Conducted a factorial experiment with five tropical Alfalfa varieties.
  • Applied drought stress using varying concentrations of polyethylene glycol (PEG).
  • Measured germination traits and antioxidant activities over the germination phase.
  • Drought stress significantly affected germination metrics like mean time to germination and final germination percentage.
  • All genotypes except two showed significant variation in germination indices and antioxidant responses.
  • Baghdadi and Yazdi varieties exhibited the highest final germination percentages and antioxidant activities.
