Effects of some internal and external conditions on seed germination

Part of the Handbuch der Pflanzenphysiologie / Encyclopedia of Plant Physiology book series (532, volume 15)


The preceding chapters of this volume were dealing with the dormant seed, that is a seed which, while fully viable, does not possess its maximal germination potential. Changes in dormancy are expressed in terms of the germination behavior of the seed, but germination is a tool rather than the immediate object of the study. The present chapter and the following one will deal with the physiology of seed germination as such, i.e. they will be concerned with seeds which are fully able to germinate as soon as given the conditions directly necessary for activity (mainly, sufficient moisture, air and proper temperature) and which may be called quiescent seeds.
