Efecto de aspersiones foliares con una mezcla de oligogalacturónidos en el crecimiento de plantas de palma areca (Dypsis lutescens H. Wendel)
Main Article Content
Abstract
Dypsis lutescens, is one of the most worldwide used plants for
landscape gardening, besides being considered among the
most popular interior plants; Golden Cane or Areca Palm hardly
needs to be introduced. Pectimorf is a plant biostimulant
obtained from the enzymatic degradation of citrus peel pectic
acid at the Department of Crop Physiology and Biochemistry
from the National Institute of Agricultural Sciences (INCA).
Due to short viability, seeds are all seeded at the same time,
achieving their optimum status for marketing in unison;
therefore, the aim of this research work was to evaluate the
effect of Pectimorf on areca palm (Dypsis lutescens) plant
growth. The experiment was carried out at INCA, where
Pectimorf was sprayed (1, 5 and 10 mg.L-1) to leaves and there
was a control treatment. Sprayings were applied three times: at
three, three and six months as well as three and nine months;
evaluations were recorded three times along crop cycle: after
six, nine and 12 months of plant emergence. The following
growth variables were estimated: plant height, stem diameter
(ø), leaf number, root length, dry matter from roots and the
aerial part. Results showed Pectimorf potentiality as a plant
growth stimulator of areca palm; when plants were sprayed at
three and six months by means of 1 mg.L-1 concentrations,
growth variables related with plant aerial part increased
significantly compared to control treatment, enhancing the
ornamental properties of this species.
