Root characteristics of Bactris gasipaes H.B.K.
Due to its extraordinaryly high biomass production and its suitability as "multi purpose" plant (palm heart, fruits, oil, starch, wood, leaf fiber), the plant is used as production factor in the polycultural systems of SHIFT ENV/23 Project. Results on morphology, biology, and anatomy of the peach palm tree are describe. The polyarchic root systems of the first, second and third order have no fine roots. The exodermis consists of extraordinary large-lumen cells of a maximum diameter of 120um, which are located at the basis on small, axially expanded hypodermis cells. The exodermis cells are closely adjoined, but they are not junctioned at the side. They form a very large contact surface. The surface area which is formed by this structure is 2 to 2.5 time larger than the corresponding surface of a root cylinder. This surface area enlargement corresponds to the surface area enlargement caused by root hair in other plants having the factor of 1.4 to 2.9.
