A. trichopod in vitro pollen germination and PT growth. A, In vitro pollen germination on solidified CJ-PGM. Scale bar = 100 µm. B, Time series of a growing PT monitored 15 to 34 min after germination on solid medium. An average growth rate of 100.46 ± 0.5 µm h−1 was observed. Scale bar = 20 µm. C, Kymograph analysis of the PT shown in B. The growth profile appears linear lacking any signs of oscillation. Scale bars for time and distance are shown in the bottom right corner.
