Correlations of final germination percentage of each population with seed weight and various geographic parameters (longitude, latitude, and altitude) were studied. For each species, final germination percentages were highly variable depending on the population, ranging from 16 to 95% for Lavandula stoechas, 4-95% for Thymus zygis, 13-90% for T. vulgaris, 35-95% for T. mastichina, and 21-91% for Origanum vulgare. Similarly, germination rate (T50) varied significantly. A significant relationship between seed weight and final germination percentage was identified for the populations of L. stoechas and O. vulgare. Moreover, germination percentages correlated significantly with altitude in T. mastichina, and with longitude in O. vulgare. In addition, seed weight showed a significant relationship with longitude in O. vulgare and with latitude in T. mastichina.1 aPérez-García, F1 aHornero, J1 aGonzález-Benito, M, E  uhttp://muse.lib.auth.gr:9797/com/csa/?MuseHost=www-mi2.csa.com&MuseFirst=1&id=2&recnum=5&SID=54cb5ee3ad7ac982e501634b8323fbe4&MusePath=/ids70/view_record.phphttp://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-17144452965&partnerID=40&rel=R6.5.002326nas a2200157   4500008004100000245010400041210006900145260001200214300001400226490000700240520174200247100001701989700001802006700002002024856012402044       2002                        eng d00aEffects of temperature and pretreatments on seed germination of nine semiarid species from NE Spain0 aEffects of temperature and pretreatments on seed germination of   c2002///  a103 - 1120 v503 aThe aim of this work was to study the seed germination characteristics, under different incubation temperatures and using different pretreatments for promoting germination, of nine species, Boleum asperum (Pers.) Desvaux, Centaurea pinnata Pau, Halopeplis amplexicaulis (Vahl.) Ung.-Sternb, Krascheninnikovia ceratoides (L.) Gueldenst, Lythrum flexuosum Lag., Microcnemum coralloides (Loscos & Pardo) Buen, Pucinellia pungens (Pau) Paunero, Thymus loscosii Willk., and Vella pseudocytisus L. subsp. paui Gomez Campo, that grow in semiarid regions of NE Spain. In eight of these species, seeds collected from several (2-9) populations were tested. Constant 15 degreesC, 20 degreesC, or 25 degreesC, and alternating 15/25 degreesC temperature regimes and 16/8 hours light/dark photoperiod conditions were used. In seeds from the different populations of Halopeplis amplexicaulis and Microcnemum coralloides, manual scarification, dry heat, and soaking in gibberellic acid solution were used as pretreatments applied for enhancing germination. Germination variables recorded were final germination percentage and germination rate (T,,). Incubation temperatures had a significant effect on the final germination percentage in five species, while germination rate was differentially affected by temperature in only two species. Significant differences among populations under the same temperature were detected for both germination percentage and germination rate in most of the species studied. In general, both final germination percentage and germination rate of H. amplexicaulis and M. coralloides were increased by the pretreatments assayed. In these two species, the highest germination percentages were reached by manual scarification.1 aAlbert, M, J1 aIriondo, J, M1 aPerez-Garcia, F  uhttps://thymus.myspecies.info/ref/effects-temperature-and-pretreatments-seed-germination-nine-semiarid-species-ne-spain
