Variability in seed germination behaviour of Cistus ladanifer L. (rockrose), a Cistaceous species widely distributed in the Mediterranean Basin, was studied in a central Spanish population under…

The spatial community pattern detected in this gypsum environment and characterised by a sharp ecotone could be at least partially controlled by interference through allelopathy, which determines the excliusion of Helianthemum squamatum plants from alluvial soils.
Seed germination of high mountain Mediterranean species: altitudinal, interpopulation and interannual variability

High mountain Mediterranean species do not differ from alpine species except that a relatively high number of species are ready to germinate without any treatment, which could be interpreted as an efficient survival strategy for species growing under unpredictable environments, such as the Mediterranean climate.
Effects of light, temperature and population variability on the germination of seven Spanish pines

Nested models showed that there was no phylogenetic control of the germination response and, surprisingly, germination traits were not related to habitat preferences, and it is believed that studies of theGermination characteristics of a pine species should consider different populations.

Effect of dry-heat, soaking in distilled water and gibberellic acid on the germination of Cistus clusii, C. monspeliensis and C. salvifolius seeds

- Biology
- 2002
Results indicated that hardness and impermeability of seed coats to water uptake might be the most important cause of the dormancy present in seeds of C. clusii, C. monspeliensis and C. salvifolius.
Environmental maternal effects on seed morphology and germination in Sinapis arvensis (Cruciferae)
- A. Luzuriaga, A. Escudero, F. Pérez-García
- Biology
- 1 April 2006
Evidence for maternal environmental effects on germination under field conditions is provided and changes in germination timing, as detected in this study, may determine plant development and fitness in unpredictable conditions.
Seed germination of gypsophytes and gypsovags in semi-arid central Spain
- A. Escudero, L. F. Carnes, F. Pérez-García
- Environmental Science
- 1 July 1997
It seems patent that gypsum has acted interactively at the seedling and mature stages of these plants, but it has not forced different strategies at the germination stage.
Activity of plant extracts on the respiratory burst and the stress protein synthesis.

The best inhibitory activity was shown by the dichloromethane extracts of Baccharis grisebachii and Pluchea sagittalis that were active in all the assays.
GERMINATION STUDIES IN ENDEMIC PLANT SPECIES OF THE IBERIAN PENINSULA
- F. Pérez-García, J. Iriondo, C. Perez
- Environmental Science
- 13 May 1995
Nine plant species of the Iberian Peninsula, four of them catalogued as vulnerable or endangered by the International Union for the Conservation of Nature, was studied under controlled laboratory conditions, and high germination rates were obtained at alternating temperatures.
