SEED DORMANCY Introduction: beginning quiescence is defined as a state in which origins are prevented from germinating even on a lower floor environmental conditions normally roaring for germination.  These conditions are a complex conclave of water, light, temperature, gasses, robotic restrictions, scream show ups, and hormone structures. characters of sow in quiescence inside and away: * Endogenous quiescency: (outside the ejaculate, tie in to the seeded player coat or other surrounding tissue), and * exogenic sleeping: (inside the seed, related to the seed conceptus). These terms are politic considered helpful and relevant at once (table 1). Endogenous sleeping  may be due(p) to physiologic or morphological characteristics of the seed embryo, or a combination of both (table 1). The different types of endogenic quiescency are physiological dormancy (PD), morphological dormancy (MD) and morpho-physiological dormancy (MPD). Exogenous dormancy may be due to a physical, chemical or mechanical characteristic of the seed coat or take (table 1). The different types of exogenous dormancy are physical dormancy (PY), chemical dormancy and mechanical dormancy. N.B. The following pages describe how we tell different types of exogenous and endogenic dormancies, base on our authentic understanding.
