Abstract
Different dormancy-breaking pretreatments were assessed in order to im prove germination of caper (Capparis spinosa L.) seeds. High germinati on percentages were obtained using concentrated sulfuric acid, followe d by either a 90-min soaking procedure in a 100 ppm gibberellin (GA(47)) solution, or adding 0.2% potassium nitrate to the test substrate. Results obtained by means of a surgical treatment clearly suggest that the dormancy of the caper seed is imposed by its covering structures.
