Written by Ion SĂRĂCIN, Olimpia PANDIA

The fact that the seeds of some forest species after maturation become profoundly dormant, leading to germination andemergence in the second year after planting, requires some investigation undertaken in order to reduce profounddormancy, considering that mechanical degrading of seminal coatings is a difficult operation which can lead toinjuring the endosperm. In their turn, mechanical treatments can provide fast germination imbibitions, but doneincorrectly, they can reduce germination potency.This paper presents a mechanical method for reducing profound dormancy by degradation of the per carp and seedcoat permeability for rapid penetration of water into the seed, the method to apply the mechanical treatments undervarious conditions of time, temperature and humidity.
