GERMINATION RESPONSE TO SELECTED SCARIFICATION TREATMENTS OF Anthocleista vogelli Planch AND Albizia coriaria Welw. ex Oliv. SEEDS

ABSTRACT

Seed scarification is a crucial technique employed to enhance germination rates and break seed dormancy in various plant species. This study specifically focuses on the scarification methods used for Albizia coriaria and Anthocleista vogelii seeds. Both species exhibit hard seed coats that hinder germination, making seed scarification a pivotal step in their propagation.The experiment conducted aimed to determine the best pre-germination treatment to improve germination rates of Albizia coriaria and Anthocleista vogelii seeds. The study explored various scarification methods, including chemical scarification (acid treatment), hot water treatment, and dry heat treatment.Scarification. Sulphuric acid (H2SO4) proved to be the most effective method for Albizia coriaria seeds, achieving the largest germination percentage rate. However, hot water treatment and dry heat treatment were found to be ineffective for both species, as it failed to break the seed coat and inhibited germination. The impermeability of the seed coat was identified as a major hindrance to germination in Anthocleista Vogelii seeds. This suggests that further research is warranted to identify the most effective scarification protocols for these valuable plant species. Successful propagation and conservation efforts rely on the development of optimal scarification techniques. This study provides valuable insights into the scarification methods that can be used to enhance germination rates in Albizia coriaria and Anthocleista vogelii seeds. The findings emphasize the importance of identifying the most effective scarification protocols for these species, contributing to successful propagation and conservation efforts. Further research is necessary to overcome the challenges posed by the impermeable seed coat of Anthocleista vogelii seeds.
