Abstract
SUMMARY Plants of Rosa hybrida L. cv. ‘Samantha’, grown with high or low phosphorus (P) fertilization, were inoculated with Glomus intraradices Schenck & Smith, G. deserticola Trappe, Bloss & Menge, or left non‐mycorrhizal. All plants except the low‐P non‐mycorrhizal group had similar tissue dry weights, leaf and root surface areas, growth ratios, stomatal characteristics and P contents. The higher rate of P fertilization increased plant dry weight three‐fold and leaf area four‐fold in non‐mycorrhizal plants, but had no effect on growth characteristics of mycorrhizal plants except for a depression of colonization levels. Under well‐watered conditions (75–90% and 45–50% relative soil water content, θ), low‐P mycorrhizal plants displayed greater leaf conductance ( g ) than both high‐P mycorrhizal and non‐mycorrhizal plants. Leaf water potential (Ψ) was similar in colonized and uncolonized roses. Fungal species did not differ significantly in their influence on Ψ or g .
