The causal factors may be of two kinds. Growth may be stopped because of external conditions, i.e., unfavorable temperature, water supply, etc; this kind of dormancy we shall call "quiescence," as suggested by Meyer & Anderson (87). The second, that dormant state which is caused by internal factors, i.e., a suspension of growth which continues even under favorable external conditions, we shall call in agreement with Chandler (19) "rest." It seems useful to agree on some terminology which differentiates between these concepts, since they describe physiologically different phenomena. Nevertheless, even recent treatises on plant physiology do not distinguish between "dormancy" and "rest."
