Response Of Five Chenopodium Quinoa Varieties To Different Salinity Levels, Elevated Co₂ And Uvb, Saif Ali Matar Al Blooshi
Response Of Five Chenopodium Quinoa Varieties To Different Salinity Levels, Elevated Co₂ And Uvb, Saif Ali Matar Al Blooshi
Theses
Ecosystems have been affected by climate changes. Both agriculture and environmental changes are correlated with various features since climate change is the main cause of abiotic and biotic stress which affects crop plants. The climate changes and their severe impact on plant productivity showed great intensities due to the effects of abiotic stress. In the present investigation, five quinoa varieties viz KAUST- 05395/CHFN-68 (V1), KAUST-05398/PI-614889 (V2), KAUST-05397/PI-614885 (V3), KAUST-05403/ICBA-Q3 (V4), and KAUST-05399/PI-614888 (V5) were screened for their salinity stress response by measuring the morphological parameters such as total plant height, fresh and dry weight of shoot and roots. V4 and …
Abiotic Stress Effect On Growth And Photosynthetic Characteristics In Emirati Date Palm Varieties, Nasser Abdullah Ghdayer Al Kaabi
Abiotic Stress Effect On Growth And Photosynthetic Characteristics In Emirati Date Palm Varieties, Nasser Abdullah Ghdayer Al Kaabi
Theses
Plants are naturally exposed to various environmental stresses that affect their growth and development. As a desert plant, date palm has developed strategies to protect itself from most abiotic stresses. However, projected climate changes and the interaction between the various abiotic stressors will have profound effects on date palm adaptation and production. In the present study, five date palm cultivars, namely Chichi, Kalas, Nabt Saif, Sultana and Zamli, were initially evaluated for salinity tolerance by measuring the growth parameters such as plant height, fresh weight and dry weight of shoots and roots. Based on the obtained results, Sultana and Zamli …
Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali
Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali
Theses
The stratospheric ozone depletion and elevated solar UV-B radiation have a negative effect on living life forms. UV radiation is one of the unsafe components that cause hindrance to both flora and fauna on the earth. This will have important implications for ecosystem processes and food production. The present study has been designed with primary objective of the effect of UV-B radiation on five numbers of most cultivated Emirates varieties (i.e., BARHI, FRDWT, NBTSF, FRDRD and KHD). After 4 and 8 hrs/day UVB treatment the Shoot, Root and total Plant length, Total plant fresh weight, Shoot and Root fresh and …
Effects Of Glycine Betaine On Plant Growth And Performance Of Alfalfa (Medicago Sativa L.) & Cowpea (Vigna Unguiculata L. Walp.) Within Water Deficit Conditions, Hanan Kamal Khadouri
Effects Of Glycine Betaine On Plant Growth And Performance Of Alfalfa (Medicago Sativa L.) & Cowpea (Vigna Unguiculata L. Walp.) Within Water Deficit Conditions, Hanan Kamal Khadouri
Theses
Managing water consumption of the crops is one of the strategies which have been adopted locally and worldwide in current trends of sustainable agriculture, in addition to the low level of water resources in UAE because of the rare precipitation, no fresh free flowing water; no rivers, lakes or streams. The present study was objective to evaluate the effects of organic exogenous Glycine Betaine on two forage crops Alfa alfa (Medicago sativa L.) & Cowpea (Vigna unguiculata L. Walp.) within different levels of drought stress. A pot experiment was designed on completely randomized block design (CRBD) with three replicates in …
Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, Mohamed Abdulla Al Muhairi
Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, Mohamed Abdulla Al Muhairi
Theses
Economically important vegetable crop lettuce (Lactuca sativa L.) of family Asteraceae was selected for the present investigation. It is being cultivated in UAE due to its commercial importance. In lettuce cultivation, major problem is the requirement of large quantity of irrigation water. The present study was aimed to reduce the water consumption of lettuce cultivation, for that, a varied irrigation regime was used with the application of abscisic acid (ABA). The parameters studied were growth, photosynthetic pigments, biochemical constituents, antioxidant potential and antioxidant enzymes activities in lettuce plants under drought stress and its response to ABA under stress. Drought stress …
