Anatomical Analysis And Seed-coat Imposed Dormancy In Parkia Biglobosa

The effect of different treatments of breaking seed dormancy of Parkia biglobosa seeds were studied in this project work. The results of different treatments observed showed 88% for concentrated H2SO4, 80% for scarification (with scalpel) and 52% for dry heat while the untreated seed (control) is 40% germination. The speed of germination for some treated seeds are also observed to be greater than that of the untreated seeds with seeds treated with concentrated H2SO4 having the highest value of 32.35%, followed by mechanical scarification with 26.67%, heat with 13.97% and untreated seeds having…
