Respiratory response of parsley cell suspension cultures after treatment with the priming compound SA and Pep13. Oxygen transfer rate as a function of time of parsley suspension cultures treated with 100 μM salicylic acid (SA) and 50 pM Pep13 (red circles). Reference cultivations: w/o additives (black squares), with addition of exclusively 100 μM SA (blue diamonds), and with the addition of exclusively 50 pM Pep13 (green up triangles). SA was added after 72 h and Pep13 after 96 h. Cultivation conditions: 250 mL flask volume, 50 mL filling volume, 180 rpm shaking frequency, 50 mm shaking diameter, and 25 °C. Arrows indicate the addition of SA, Pep13, and sampling for the 2D-fluorescence measurements. Experiments were conducted in duplicate (open and closed symbols)
