Overcoming dormancy of seeds of Copaifera arenicola (Ducke) J. Costa & L. P. Queiroz [PDF]

Journal of Seed Science
: Seed dormancy can occur due to a combination of intrinsic factors and stimuli from the external environment. From a production perspective, it is an undesirable characteristic, as it hinders germination and limits production.

Effect of mechanical scarification, chilling, and gibberellic acid on germination of Leucaena leucocephala seeds

Journal of Biotechnology Research Center, 2013
Leucaena leucocephala is a tree species used for several agricultural purposes in Mediterranean region. The seeds of these species exhibit dormancy causing delayed germination. A series of experiments evaluated the effects of various treatments on the germination of leucaena leucocephela L. seeds. Germination of fresh seeds was 46% but it was improved (

Mechanical scarification: The key to optimal germination parameters in nine flowering species of the United Arab Emirates

Innovations in Agriculture
Seed germination is the most essential stage of the plant life. Prior to germination, seed dormancy provides protection to the seed against germinating under unfavorable conditions. The seeds of many plants in arid regions are particularly characterized by having a hard seed coat.
