- Abstract:
- ... Nickel contamination may have an adverse impact on the fragile coastal and marine ecosystems of the Arabian Gulf. Oil pollution is a major source of this heavy metal. The nickel concentrations were measured in seawater and in 12 species of green, brown and red algae which were collected from Dammam area on the Saudi coast of the Arabian Gulf. The algal samples were cleaned, air dried and digested ...

- Abstract:
- ... The availability of genetically based variation is essential for bringing rapid improvement in salinity tolerance of a crop through rapid selection and breeding. To get such information in Gossypium hirsutum L., a sample of eleven cultivars of diverse origin was assessed at seedling stage using three salinity levels of NaCl solutions including control. Variation was found in seedling response to i ...
