Growth Response of Drought-Stressed Pinus sylvestris Seedlings to Single- and Multi-Species Inoculation with Ectomycorrhizal Fungi
Figure 4
Enzyme activity in root tips from Pinus sylvestris seedlings.
Seedlings were non-mycorrhizal or infected with monocultures of Cenococcum geophilum, Paxillus involutus, Rhizopogon roseolus or Suillus granulatus, respectively, and grown under two watering regimes (d = dry, m = moist). Different letters indicate significant differences in overall enzyme activity between treatment combinations (P<0.05, Tukey’s HSD test). Whiskers indicate standard errors of overall enzyme activity.
