Only the core of the palm tree stem is extracted for trade and food production purposes; leaves and outer and median leaf sheaths
are discarded, which generates residue accumulation in the order of 80-90% of the total gross weight.
2 Plan view of a palm leaf with locations of the three distinct types of stem nodal buds and thus branching types; the stem is not drawn but the encircling leaf base is shown, a Axillary branching--the meristem arises in the axil of the leaf; b Abaxial branching-the meristem is located on the base of the leaf sheath
, on the abaxial surface of the leaf; and c Leaf-opposed branching-the meristem is borne on the stem of the palm, enclosed by the outer edges of the leaf sheath
and opposite to the lamina and petiole
Lower surface of leaf sheath
