Figure 2. Main classes of palm seed germination. A-B. Remote germination, date palm (Phoenix dactylifera). A. Early germination with cotyledonary petiole emerged and seedling root (radicle) beginning growth. B. Seedling stem (plumule) emerging from cotyledonary sheath. C. First leaf (eophyll) emerged, radicle continuing to elongate, and haustorium inside seed absorbing nutrients from endosperm. D-F. Adjacent germination, piccabean palm (Archontophoenix cunninghamiana). D. Early germination with button emerged. E. Seedling root (radicle) and stem (plumule) emerging from button. F. First leaves (eophylls) emerging, first adventitious root formed and supplanting radicle, and haustorium inside seed absorbing nutrients from endosperm.
