Juvenility in micropropagated plantlets versus rooted cuttings of maqui (
Aristotelia chilensis
)

T
he antioxidant “superfruit” maqui (
Aristotelia chilensis
) is coming from a woody plant native to Chile and
West-Patagonian areas of Argentina. It is a sacred medicinal plant of the indigenous Mapuche people. Up to
now the rising international demand for maqui-berries is coming from wild collection. To provide in the future
high quality and sustainable raw material for processing industry our research group has selected high-yielding
genotypes that are propagated vegetatively, exploring also micropropagation techniques. As in some other woody
plants micropropagation promotes juvenility expressed by a delay in fruit production. The objective of the present
study was to compare young plantlets of the same age coming from in vitro propagation and rooted cuttings. In half
of the plants the apical sprout was removed. Six clones were established in April 2017 (autumn) in field trials in an
experimental design with four treatments and five replicates. During the following spring (December 2017) one of
the genotypes ('Luna Nueva') produced fruit in all treatments, in three others ('Perla Negra', '304', and '319') only
the rooted cuttings bloomed, and two of the genotypes ('218' and '622') produced flowers just in the following year
(October 2018), when all studied genotyps and all plants had overpassed juvenility.
