Resumen

DORIA GONZALEZ, Jessica; BENITEZ FERNANDEZ, Bárbara  y  SOTO CARRENO, Francisco. Influence of different preservation methods on the germination of areca palm (Dypsis lutescens, H. Wendel). cultrop [online]. 2012, vol.33, n.2, pp.56-60. ISSN 0258-5936.

Given the importance ornamental that presents the areca palm (Dypsis lutescens. H. Wendel) in our country, this paper was developed at the National Institute of Agricultural Sciences (INCA) in order to find alternatives for the conservation of seeds of this species, to increase the period of viability. A study of conservation of seeds in the period from September to February, in the years 2009 and 2010, using different containers (black plastic bags, cloth bags and plastic containers) and two storage conditions (temperature and fourth air-conditioned). The percentage of germination was assessed for that month and seeds were removed and placed to germinate in petri dishes, randomly distributed, with six replicates per treatment, 15 seeds were used on each plate. It also determined the percentage of moisture in each assessment. The result was that for both years the best germination percentages were found in seeds kept in nylon bags, reaching up to 50 % in 2009 and 80 % in 2010, 90 days after the conserved seeds, not so for the rest of the treatments, where germination was almost zero after two and three months of storage, reaching values of 10 and 25 %. In relation to the percentage of moisture, the seeds preserved in hermetically sealed containers had the highest values, whereas those stored in cloth bags, exhibited the lowest percentages in both study periods.

Palabras clave : humidity; viability; storage; longevity.
