Description
Summary:Molina-Guerra et al discuss the germination of Amoreuxia wrightii species at risk of extinction in Northeastern Mexico. Bixaceae is a group of perennial plants that includes two genera: Cochlospermum (trees and shrubs) and Amoreuxia (herbaceous); this family has about 15 to 20 species distributed in America, Africa, Asia and Australia. The authors evaluated, in lab conditions, the speed and the capacity to germinate of A. wrightii. Given the hard seed coat present in the seed we hypothezised that seeds must have physical dormancy and tested whether seed scarification promoted germination.
