Ecology of seed dormancy and germination of Carex divisa Huds.: Effects of stratification, temperature and salinity
Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

Thus, the excessive harvest of this species within its natural habitats has increased. Therefore, the species is enlisted as prone to extinction. Due to the lack of information about germination ...
متن کاملSeed germination requirements of four species co-occurring in a Wisconsin sedge meadow
Seeds of four colonizing species which occur together in a recently revegetated sedge meadow were tested for germination after storage under three different conditions. Seeds were tested at an alternating temperature regime of 21° C dark, and 32° C light. Three species, Bidens frondosa, B. coronata, and Scirpus cyperinus germinated most successfully when stored under moist-cool conditions. Germ...
متن کاملEffects of Cold Stratification and Ga3 on Germination of Arbutus Unedo Seeds of Three Provenances

Fresh fruits of A. unedo are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements. MATERIALS AND METHODS The effects of gibberellic acid (GA3) and cold stratification (CS) on seed germination performance were inv...
متن کاملEffects of cold stratification on germination rate and percentage of caper (Capparis ovata Desf.) seeds.
Caper is an important plant because of its high adaptability to marginal agriculture fields that are not suitable for agricultural crops. Different parts of caper such as roots, fruits, flowers and buds can be used to increase the inhabitant's income. The goal of this research is to determine germination rate and percentage of caper according to different duration of cold stratification (10, 20...
