“…The seed weight of C. guianensis varied within a broad range (i.e., from 23.36g to 49.60g), with an average of 35.7g. This value is higher than reported by Hernández-Coronado et al (2018), who found an average weight of 22.1g based on 100 seeds. Similarly, Kossmann et al (2002) reported weights between 25 and 32g and established that 30-50 seeds are required to obtain 1kg.…”

“…For C. guianensis¸ germination behavior is variable; for instance, 24% to 90% germination can be reached in different periods ranging from days to months (Kossmann et al, 2002;Amaral et al, 2017;Hernández-Coronado et al, 2018). Therefore, nursery propagation alternatives for this species have led to the use of different pre-germination treatments such as mechanical scarification, sunlight exposure, and seed imbibition in sand and soil substrates (Torres et al, 2017).…”

Phosphoric rock is the main source of phosphorus used in fertilizers. In most cases, it is applied alone or mixed with other nutrients in water; however, its low solubility means that it is not used efficiently, causing excess phosphorus to be wasted. As a result, it generates economic expenses to the farmer, or causing problems of eutrophication in water sources. In this article, different mixtures of solubilizing fungi with coffee pulp stillage were studied to improve phosphates’ solubility in phosphate rock. Despite that in different studies is clear the fungi’s role in P solubilization, its application on soils is still made without any additional treatment. Phosphoric rock samples were obtained from the municipality of Aipe (Huila) and were treated for 6 weeks with coffee pulp stillage (Coffea arabica) and inoculums of Aspergillus niger and Penicillium sp, pH and temperature controlled. The fungus species were obtained from environmental media on PDA culture, then it was isolated and identified on MEA culture according to standard morphologic identification methods. Aspergillus niger showed greater mycelial growth in the stillage and a higher concentration of phosphates dissolved in the aqueous phase (72 ± 31 M) compared to Penicillium sp. The mixture of the two fungi in the treatments allowed to obtain the highest percentage of phosphates (17.8% of the phosphate soluble in H2SO4 40% v / v).

“…accordingly, T4 in S1 showed the highest germination percentage than other substrates and treatments. Overall, C. guianensis was found to germinate gradually, which agrees with reports byVillota (2016) andHernández-Coronado et al (2018).…”

“…Therefore, information about germination dynamics and seed morphology are important to establish seed collection and management guidelines to successfully propagate this species (Abbade and Takaki, 2014;Peixoto et al, 2019). For C. guianensis¸ germination behavior is variable; for instance, 24% to 90% germination can be reached in different periods ranging from days to months (Kossmann et al, 2002;Amaral et al, 2017;Hernández-Coronado et al, 2018).

Understanding seed germination of native forest species of the Tropical wet forest is essential for ecosystem regeneration and conservation, which have been affected by the exploitation of wood and non-wood forest products. Carapa guianensis Aulb. (Meliaceae) has been exploited due to the high quality of its wood and seeds. Particularly, the latter is a source of a medicinal oil of high value to the pharmaceutical industry. The indiscriminate use of this species has reduced its population size; therefore, scientific knowledge of its sexual propagation in nurseries is vital. This research aimed to evaluate seed germination of C. guianensis under different pre-germination treatments and substrates at the Centro de Investigación El Mira of AGROSAVIA. Pre-germination assays were conducted in a split-plot design with a random distribution of four repetitions. The cumulative germination percentage (CGP) and mean germination time (t50) were calculated and analyzed through an ANOVA, and Tukey’s multiple comparison test using InfoStat V.2016. Significant differences for CGP among treatments (p<0.0001) and interactions (p<0.0096) were found. The highest germination percentage (61%) was achieved in S1+T4; however, the T50 did not show significant differences (p=0.24). This research demonstrates that the highest germination percentage is achieved through a scarification treatment with imbibition in sand substrate under the agroclimatic conditions of Tumaco.

“…En el caso de las semillas no germinadas y no depredadas, los bajos porcentajes de germinación pueden deberse, entre otras causas, a que estas especies presentan semillas recalcitrantes, por tanto, requieren de las condiciones adecuadas para germinar. Asimismo, las semillas de estas palmas requieren de procesos de escarificación para su pronta germinación [30].…”

El éxito reproductivo de las plantas depende de la dispersión de sus semillas. Uno de los procesos que influye sobre esta dispersión es la depredación. En particular, la depredación posdispersión influye en la supervivencia y la distribución espacial de las plantas. En este trabajo se evaluó la relación de la depredación posdispersión de las semillas de tres palmas, Oenocarpus bataua, Euterpe precatoria y Socratea exorrhiza, con los patrones de denso-dependencia, el tamaño de las semillas y la germinación en un bosque del oriente colombiano. De cada especie de palma se seleccionaron tres individuos, en los que se recolectaron semillas de acuerdo con su patrón de agregación, cuarenta semillas agregadas y cuarenta semillas no agregadas. A las semillas se le determinó el peso, el diámetro, la germinación y la depredación. Se encontró que el tamaño de las semillas fue diferente en las tres especies de palmas, existe una correlación positiva entre el peso y el diámetro de las semillas, los porcentajes de depredación son de aproximadamente el 50 %, y una relación entre la germinación de las semillas y su depredación. Así, las dinámicas poblacionales de las palmas estudiadas se pueden asociar a características de sus semillas tales como tamaño, germinación, denso-dependencia y su capacidad de resistir a los depredadores.
