Abstract

Effect of Seed Dormancy Breaking Treatments on Germination and α-amylase Enzyme Activity in Seeds of Three Ecotypes of Astragalus (Astragalus cyclophyllu)

Highlights

  • Seed dormancy, as a technique to avoid environmental stress, is important in preserving plant species and could be of various types including physiological, physical, morphological and morphphysiological dormancy

  • The present study investigated seed dormancy and germination to find the most appropriate treatment for the elimination of seed dormancy in three ecotypes of Astragalus cyclophyllus

  • Highlights: 1- The effect of different dormancy breaking treatments on seed germination was investigated. 2- Alpha-amylase activity of Astragalus Seed increased under dormancy breaking treatments
