Abstract
The aim of this study was to evaluate the germination of wild seeds of Apeiba glabra Aubl., as well as plant growth (in height and diameter) and survival. The experimental design used was completely randomized with a factorial arrangement and 16 factors, resulting from combinations of substrates and pregerminative treatments. The experiment was developed in two germination beds previously built under shade and solar exposure conditions. Sowing was comprised of 1,920 seeds and the evaluation process was carried out during 75 days. Seed scarification with sandpaper and immersion in water for 48 hours increased germination by 33% and 34 %; moreover, these values increased to more than 50% by evaluating the interaction with a substrate composed of sifted soil and sifted soil + sand in a 2:1 ratio. Growth results in diameter and height showed significant differences among factors and light conditions, both in diameter and height (p<0.05). Seedling growth and survival were higher with the factors comprised of sifted soil (with and without pregerminative treatment). Furthermore, for propagation purposes and under our study conditions, Apeiba glabra responds well when using sifted soil and scarification with sandpaper.
期刊介绍:
The journal Ciencia y Tecnología Agropecuaria (Science and Agricultural Technology) is a four-monthly scientific publication edited since October 1996 by the Corporación Colombiana de Investigación Agropecuaria - Agrosavia. The journal publishes articles on diverse thematic areas typical of the agricultural sector (multidisciplinary), written in Spanish or English, especially from Latin American and Caribbean researchers. The contributions that apply for the journal must be original and unpublished. The articles are reviewed by national and international peers (peer review). The journal is non-commercial and open access, this means that it doesn’t charge for the reception and/or publication of articles in both, its printed and digital version. The journal is aimed at the scientific community of the agricultural sector in Latin America and the Caribbean.
