Fruit And Seed Morphology Of The Fumaria L. Species (Papaveraceae) Of Iran, Fatemeh Ebrahimzadeh Araii, Maryam Keshavarzi, Masoud Sheidaii, Parinaz Ghadam
Turkish Journal of Botany
The macro and micro fruit and seed morphology and surface ornamentations of 21 populations of 6 Fumaria L. species were investigated using stereomicroscope and scanning electron microscopy. These data are shown to support data from the general morphology. The results indicate that the fruit and seed characters of the genus Fumaria are valuable for taxonomic applications and are useful for classification. F. officinalis show a different shape in their fruit. The close relationships are observed for F. parviflora and F. vaillantii. F. indica, as a hybrid between F. asepala and F. parviflora, shows intermediate micro-morphological features.

Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe
Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe
Turkish Journal of Botany
Conservation of genetic diversity is important for continued evolution of populations to new environments, as well as continued availability of traits of interest in genetic improvement programs. Rapidly changing climates present new threats to the conservation of forest genetic resources. We can no longer assume that in situ reserves will continue to preserve existing genetic diversity. Management of reserves should become more active. In some reserves, existing genetic diversity should be preserved by creating stands that are more resistant to threats using silvicultural treatments such as thinning and prescribed burning. In other reserves, natural selection and adaptation to changed environments …
