| Abstract |
| Arbuscular mycorrhizal fungi (AMF) form mutualistic associations with roots of most terrestrial plants, including many agricultural crops. The experiment was conducted during summer season (2019), the objective of this study was to investigate the potential role of AMF inoculation and their possible benefit on phosphorus acquisition efficiency (PAE) in four sorghum(Sorghum bicolor) varieties vary in their strigolactones structures . The experiment was arranged in a split-plot design with the mycorrhiza in the main plot (with and without) and four sorghum cultivars as the sub-plot with three replications.. Cultivars were selected based on their strigolactones producing, Two Striga-resistant (orobanchol- producing) named Hakika and Tetron, whereas two Striga-susceptible (5-deoxystrigol-producing) named P954063 and Tabat. Cultivars were planted in two locations; White Nile and Gezira, the soils was clay. Grain and shoot phosphorus, Available phosphorus in soil ,AMF colonization, spore density and phosphorus acquisition efficiency were measured. The results showed that AMF inoculation significantly increased phosphorus concentration in grain, root colonization Percent RC%, spore density per 100g soil and phosphorus acquisition compared to non-inoculation, in the two locations. the cultivars responded differently to inoculation with AMF. P954063 and Tetron were the highest PAE, whereas P954063 was the highest Mycorrhiza responsiveness and Mycorrhiza dependency, while Tabat and P954063 were the highest RC%. |
