My hypothesis is that the presence of broccoli will have a positive effect on germination of plant seeds. In my results, I saw that the hypothesis was in my favor because the stems of experimental groups were much longer then the stems of control group. Other works that have been done by scientist which relate to my experiment include Alleleopathy.
