15 Cards in this Set

  • Front
  • Back
Stimulates stem elongation (low concentration only), root growth, cell differentiation, and branching; regulates development of fruit; enhances apical dominance
Auxin
Affect root growh and differentiation; stimulate cell dviision and growth; stimulate germination; delay senescene
Cytokinins
Promote seed and bud germination, stem elongation, and leaf growth; stimulate flowering and development of fruit; affect root growth and differentiation
Gibberellins
Inhibits growth; closes stomata during water stress; counteracts breaking of dormancy
Abscisic acid
Promotes fruit ripening, opposes some auxin effects; promotes or inhibits growth and development of roots, leaves, and flowers, depending on species
Ethylene
Inhibits root growth; retards leaf abscission; promotes xylem differentiation
Brassinosteroids
