Summary
[edit]DescriptionSporangium-Exposure-and-Spore-Release-in-the-Peruvian-Maidenhair-Fern-(Adiantum-peruvianum-pone.0138495.s008.ogv |
English: Annulus relaxation and spore ejection, recorded with 100.000 fps. For better visibility, the original movie with a resolution of 140 x 32 pixels was digitally enlarged without interpolation. Furthermore, we added a timescale and chose a very slow playback frame rate in the second part of the video for a better understanding of when the first, very fast annulus relaxation step has ended (at t = 40 μs, the vast majority of spores emerge from the apical cup). The sporangium was gripped with tweezers (MOV, 20 fps, 700 x 160 pixels, 946 KB). |
