Assessment Of Groundwater Quality In The Al Khatim And Remah Area Of The United Arab Emirates, Qasim Raza Khan
Assessment Of Groundwater Quality In The Al Khatim And Remah Area Of The United Arab Emirates, Qasim Raza Khan
Civil and Environmental Theses
Groundwater constitutes an important part of the available water resources in arid areas. Knowledge of the quantitative and qualitative status of groundwater is a key aspect in optimal groundwater management. The chemical characteristics of groundwater in two neighboring areas (Remah and Al Khatim) have been used to identify the processes controlling groundwater chemistry in the sand aquifer of Abu Dhabi Emirate, United Arab Emirates. Furthermore, the suitability of the groundwater for agricultural purposes was assessed using a range of indices. Both areas showed elevated levels of nitrate, potassium and cadmium, indicating the impact of agricultural activities. The groundwater was found …
Salt Gland Excretion Efficiency And Salinity Tolerance Of Sporobolus Species, Piumi Shrimani Weragodavidana
Salt Gland Excretion Efficiency And Salinity Tolerance Of Sporobolus Species, Piumi Shrimani Weragodavidana
Theses
Halophytic C4 grasses, including Sporobolus species, have developed specific mechanisms to cope with salinity stress. Among these, “salt glands” which are bi- cellular leaf epidermal structures eliminating excess saline ions from shoots by excretion under salinity stress. Salt glands are morphologically visible and can potentially be used for salt tolerance breeding programs. The objectives of this study were: (1) to determine the leaf salt gland excretion rates of United Arab Emirates native halophytic chloridoid grass species, S. spicatus and S. arabicus; (2) to determine if leaf salt gland excretion rate and density can effectively predict salinity tolerance among Sporobolus genotypes, …
