Intervention effect High soil nitrogen increased total plant dry weight, leaf area and xylem radius with or without gas additions.
Intervention effect High soil nitrogen increased leaf number independently of added NO2.
Association Soil nitrogen and fumigation influenced stomatal density.
Intervention effect Soil nitrogen regimes did not modify leaf injury symptoms, leaf loss, specific leaf weight or bark radius.
Intervention effect NO2 alone did not significantly increase poplar growth.
Intervention effect NO2 and O3 alone had opposite effects on specific leaf dry weight, stomatal density and bark radius under high fertilization.
Association O3 leaf injury increased alongside microscopic changes in mesophyll, bark and phloem.
Intervention effect NO2 enhanced the negative effect of O3.
