Abstract
DORMANCY of seeds of the genus Fraxinus has been variously ascribed to immaturity of the embryo1, mechanical resistance of the seed coats2,3, and the presence of growth-inhibiting substances within the pericarp3 and in the mucilage surrounding the embryo4. A recent study of dormancy in the fruits of F. excelsior L. has shown that these explanations are inadequate.
