Fig. 1. — Aspect of seedlings of Hymenaea courbaril on the 45th day after the beginning of imbibition. (A) A typical specimen of H. courbaril. Note the investment in the shoot (arrow=cotyledon). (B) Seedlings that had their shoot excised 35 d after imbibition. These will develop new branches in ∼30 d (see Santos et al., 2004) (arrow=cotyledon). (C) Closer view of the shoot, showing the eophylls (e) (first leaf) and metaphylls (m) (second leaf). (D) An etiolated seedling of H. courbaril after 20 days in darkness. Note that the hypocotyl is ∼5 times longer in the dark and eophylls did not develop, characterizing the programme of skotomorphogenesis. Bars represent 10 cm.
