Rhazya stricta, an evergreen poisonous shrub, is invading many rangeland areas in Saudi Arabia. A field study was conducted in Raudhat AI-Khafs to assess the relationship between R. stricta and Hammada elegans, a valuable and a dominant saltbush range plant in the area. Only eight perennial species were found in the site of which H. elegans and R. stricta were almost exclusively co-dominating t...
Relationships between net plant CO(2) exchange rate (CER) and canopy development were examined in ;jubilee' tomato over the initial 4 weeks of vegetative growth. A comparison was made between two plant groups that were alternatively exposed to 200 or 800 microeinsteins per square meter per second midday irradiation to establish a differential in net CER. Plants exposed to higher irradiation dem...
Effect of genotype x environment interaction was studied on relationship between yield and three yield components in 20 genotypes of chickpea. Significant differences were found between genotypes for the three yield components at all the locations. It was found that the pattern and strength of correlation between number of seeds pod and yield, between number of seeds pod and number of pods plan...
Ecosystem productivity commonly increases asymptotically with plant species diversity, and determining the mechanisms responsible for this well-known pattern is essential to predict potential changes in ecosystem productivity with ongoing species loss. Previous studies attributed the asymptotic diversity-productivity pattern to plant competition and differential resource use (e.g., niche comple...
Despite decades of research, the ecological determinants of microbial diversity remain poorly understood. Here, we test two alternative hypotheses concerning the factors regulating fungal diversity in soil. The first states that higher levels of plant detritus production increase the supply of limiting resources (i.e. organic substrates) thereby increasing fungal diversity. Alternatively, great...
Owing to its exceptional ability to efficiently promote plant growth, protection and stress tolerance, a mycorrhiza like endophytic Agaricomycetes fungus Piriformospora indica has received a great attention over the last few decades. P. indica is an axenically cultiviable fungus which exhibits its versatility for colonizing/hosting a broad range of plant species through directly manipulating pl...
