Principal growth stage 0: Germination<br />
00 Dry seed<br />
01 Beginning <strong>of</strong> seed imbibition<br />
03 Seed imbibition complete<br />
05 Radicle emerged from seed<br />
07 Hypocotyl with cotyledons breaking through seed coat<br />
09 Emergence: cotyledons break through soil surface<br />
Principal growth stage 1: Leaf development (Main shoot)<br />
10 Cotyledons completely unfolded; growing point or true leaf<br />
initial visible<br />
11 First true leaf unfolded<br />
