In the broadest sense, dormancy is the state in which a living plant organ—such as a seed, bud, tuber, or bulb—fails to exhibit growth, even when environmental conditions are considered favorable. In a stricter context, dormancy is an inhibition of growth internally controlled by factors restricting water and nutrient absorption, gas exchange, cell division, and other metabolic processes necessary for growth. What is the oldest dormant seed that has been germinated into a viable plant? Discuss
