Results of two experiments studying hyphal branching of arbuscular mycorrhiza (Glomus intradices) following exposure to WT or mutant (Sl-ORT1) or to GR24 as a positive control or sterile distilled water as a negative control

Six replicates were done for each treatment, in each replicate 10 plants were examined. Means and standard error were determined for all replicates.
