Analysis of variance (including source of variation, degrees of freedom [df], mean square values, P values, and coefficient of variation [CV]) for root colonization (Clon), shoot dry weight (DWS), root dry weight (DWR), total chlorophyll (Chlab) content, carotenoids (Car) content, DPPH activity, total phenolic (Phe) content, and essential oil (EO) content of Arizona cypress seedlings inoculated with two arbuscular mycorrhizae (Rhizophagus irregularis and Funneliformis mosseae) and one rhizobacterium (Pseudomonas fluorescens) grown under two irrigation regimes.
