Résumé : In a previous study, we found that Hypericum perforatum seeds exhibit both exogenous and endogenous dormancy and the seeds needed light for germination strictly. In this study, the effect of light was studied more deeply. For this, seeds were exposed to different light intensities (0, 600, 1200, 1800 and 2400 lux) for 6, 12, 18 and 24 h a day. According to the results, the effect of light intensities was more evident and 2102.5 lux light intensity with any exposure times evaluated in this study except for 6 h a day was found to be the most suitable treatment for breaking endogenous dormancy.

[CBNPMP-Thèmes] Système de reproductionMots-clés : Hypericum perforatum L. Résumé : The mode of reproduction was characterized for 113 accessions of the tetraploid facultative apomictic species Hypericum perforatum using bulked or single mature seeds in the flow cytometric seed screen (FCSS). This screen discriminates several processes of sexual or asexual reproduction based on DNA contents of embryo and endosperm nuclei. Seed formation in H. perforatum proved to be highly polymorphic. Eleven different routes of reproduction were determined. For the first time, individual seeds were identified that originated from two embryo sacs: the endosperm from an aposporous and the embryo from the legitimate meiotic embryo sac. Moreover, diploid plants were discovered, which apparently reproduce by a hitherto unknown route of seed formation, that is chromosome doubling within aposporous initial cells followed by double fertilization. Although most plants were tetraploid and facultative sexual/apomictic, diploid obligate sexuals and tetraploid obligate apomicts could be selected. Additionally, genotypes were detected which at a high frequency produced embryos either from reduced parthenogenetic or unreduced fertilized egg cells. The endosperm developed most frequently after fertilization of the central cell in aposporous embryo sacs (pseudogamy) but in few cases also autonomously. The genetic control of apomixis appears to be complex in H. perforatum. Basic material was developed for breeding H. perforatum, and strategies are suggested for elucidation of inheritance as well as evolution of apomixis and for molecular approaches of apomixis engineering.
