摘要

本研究的目的是评价野生大叶青种子的萌发。,以及植物的生长(高度和直径)和存活率。试验设计采用完全随机的因子安排和16个因子,由底物和发芽前处理组合而成。实验是在之前在遮荫和日光照射条件下建立的两个发芽床上进行的。播种由1,920颗种子组成,评估过程在75天内进行。砂纸划伤和浸水48h使种子萌发率分别提高33%和34%;此外,通过评估筛土和筛土+砂以2:1的比例组成的基质的相互作用,这些值增加到50%以上。生长结果在不同因子和光照条件下均存在显著差异(p<0.05)。经筛选的土壤(有和没有发芽前处理)对幼苗生长和成活率有较高的影响。此外,为了繁殖目的,在我们的研究条件下,大叶青花在筛选土壤和砂纸刻蚀时反应良好。

Germinación de semillas silvestres de Apeiba glabra Aubl. (Malvaceae) y crecimiento inicial de plantas
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 The contributions that apply for the journal must be original and unpublished.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.
