Embryo dormancy and light requirements in the germination of Helipterum craspedioides (compositae), an arid-zone annual
Annals of Botany, Vol.39(5), pp.1071-1075
1975
Abstract
Seeds of Helipterum craspedioides require light for germination, and this may be given while the seed is not fully imbibed. Removal of the seed coat, or leaching, does not bring about germination in the dark. Gibberellin enhances dark germination to some extent, whether or not the seed coat is removed. The light requirement therefore resides in the embryo. Fresh seed is dormant in light or dark. Excised embryos of these dormant seeds grow slowly, rarely giving mature plants, but a larger number of normal plants is produced after gibberellin treatment. Dormancy is lost after high temperature storage, but not stratification.
