RIVAS, Marinoli; MILLAN, Betty  and  KAHN, Francis. Morphological and anatomical comparison between axes produced by seed and basal branching of Astrocaryum carnosum (Arecaceae). Rev. peru biol. [online]. 2015, vol.22, n.3, pp.315-322. ISSN 1727-9933.  http://dx.doi.org/10.15381/rpb.v22i3.11437.

For the caespitose palm Astrocaryum carnosum are described and compared the foliar morphology and anatomy between axes produced by seed and basal branching in three stages of development; stage 1: with entire leaves; stage 2: with 2-6 pairs of irregular pinnae and stage 3: with 7-21 pairs of pinnae. For each case were considered four morphological and 14 anatomical parameters for phase 1; and 12 morphological and 14 anatomical parameters for phases 2 and 3. Significant differences (p<0.05) were found in the number of leaves, length of petiole, length of lamina, width of basal and middle pinna, thickness of spongy parenchyma, size of non-vascular fibers bundles and stomatal density.

Keywords : Huicungo; caespitose; basal branching.
