  • 26. Trial 2 Unique to trial New seeds New procedures Brenda Felix
  • 27. Trial 2 Unique to trial New seeds New procedures OBSERVATIONS Instead of planting immediately after germination, seeds were allowed to continue their growth in petri dishes Brenda Felix
  • 28. Trial 2 Unique to trial New seeds New procedures OBSERVATIONS Instead of planting immediately after germination, seeds were allowed to continue their growth in petri dishes SUCCESFUL TRIAL A Germinated and develop with more rapidity than trial 1 Brenda Felix
  • 29. Trial 2 Unique to trial New seeds New procedures OBSERVATIONS Instead of planting immediately after germination, seeds were allowed to continue their growth in petri dishes SUCCESFUL TRIAL A Germinated and develop with more rapidity than trial 1 B However, reached phase 2 only, due to experimentation deadline Brenda Felix
