Abstract

To assess mycorrhizal fungi efficiency on Acacia growth performance under water shortage condition, three leguminous plant species (Acacia tortilis, Acacia ehrenbergiana and Acacia gerrardii) were selected under greenhouse conditions in washed soil. The mycorrhizal fungal colonization was used to enhance plants growth under water deficit. Three watering levels; 85%, 75%, 50% and 25% of Field Capacity (FC) in the presence of Mycorrhizal and non-Mycorrhizal applied on grown trees for 5 months. This treatment impact on the plants was assessed by comparing plants heights, number of leaves shoot, root fresh, dry weight and Relative Growth Rate (RGR), and by measuring mycorrhizal colonization percentage and intensities. The results indicated that Arbuscular Mycorrhizal Fungi (AMF) significantly increased colonization percentage irrespective of acacia species. The maximum of root colonization percentage obtained at 75 % FC. Greater mycelium infection was observed at A. tortilis, A. gerrardii and A. ehrenbergiana (88.1%, 87.4%, and 86.4% respectively) at FC 75%, while the mycelium infection decreased at FC 25% at all species. The maximum vesicles were found with A. ehrenbergiana, A. gerrardii and A. tortilis (85.3%, 73.2%, and 53.5% respectively) at 75% FC, while the highest infection of Arbuscular (33.6%) was recorded with A. ehrenbergiana under 75% FC. Colonization intensity % significantly affect A. gerrardii registered highest mycelium intensity (66.3%) amended with 75% FC. The greater vesicles infection (62.6%) recorded with A. ehrenbergiana at the same FC, while maximum Arbuscular density (35.7%) with A. ehrenbergiana under 75% FC. Irrespective of Acacia species mycorrhizal fungi significantly enhanced the trees growth (plant height, leaves, shoot and root fresh weight, shoot dry weight and RGR) at 75% FC.
