بررسی اثر تلقیح مایکوریزا بر ریشه جو و اثر آن بر جذب فسفر

During 2010-2011 field-, pot- and glass-sided rhizotron-based experiments were carried out on spring barley (cv. Static) at the Henfaes Research Centre at Bangor University. Barley grown in field soils with low soil P status (P index 1) showed that the application of mycorrhiza (M) significantly increased P content of barley grains and stems. M colonization was found to 14.7%, P concentration of grains = 5.2 mg g-1. In the pot experiment, M treatment resulted in significant greater levels of M root colonization and P concentration in grain (8.27% and 4.31 mg g-1). The rhizotron experiment also showed that application of M significantly increased root- and shoot-P concentration (2.07 mg g-1, and 2.43 mg g-1; respectively), compared to zero-P controls (1.25 mg and 1.37 mg g-1, respectively). These studies showed the potential of mycorrhiza to mobilise P from low P status soils, enhance P uptake and increase the growth and yield of barley.
