“…Secondly, it may be related to factors influencing growth in height or crown size for a given individual tree. For example, the same species can have different heights for a given diameter due to factors such as exposure to wind, slope or soil characteristics 49 – 51 . Given that shade trees on cocoa farms are sparsely distributed with their canopies emerging above the cocoa trees to provide shade for them, the impact of wind on these trees become more intense which may result in the thickening of the stems to prevent bending and breakage 1 , 19 , 21 , 37 .…”

Allometric models which are used to describe the structure of trees in agroforestry systems are usually extrapolated from models developed for trees in forest ecosystems. This makes quantitative assessment of the functions of shade trees in agroforestry systems challenging since increased availability of light and space in these systems may induce structural differences from those growing under forest conditions. We addressed this issue by providing species-specific allometric information on the structural characteristics of associated shade trees on cocoa agroforestry systems and assessed if allometries conformed to theoretical predictions. At the plot level, stand and soil characteristics affecting tree structural characteristics were assessed. The study was conducted in cocoa agroforestry systems at Suhum, Ghana. The height-diameter at breast height (H-DBH) allometry had the best fits (R2 = 53–89%), followed by the crown area (CA)-DBH allometry (R2 = 27–87%) and then the CA-H allometry (R2 = 22–73%). In general, the scaling exponents of the CA-DBH, H-CA and H-DBH allometries conformed to the metabolic scaling theory (MST). However, both the CA-DBH and H-DBH allometries diverged from the geometric similarity model. Though forest tree species had similar crown areas as fruit trees, they were slenderer than fruit trees. Tree slenderness coefficients were positively correlated with soil P, Ca, Cu and the ratios (Ca + Mg):K, (Ca + Mg):(K + Na) and Ca:Mg, but not C:N while DBH and H were correlated with soil P and C:N ratio. Our results show that critical soil nutrients and their ratios affects shade tree structural attributes (e.g. slenderness and CA), which possibly restrict variations in species-specific allometries to a narrow range on cocoa systems. Furthermore, shade tree species richness and density are better predictors of relative canopy projection area (a proxy for shade intensity) than tree species diversity. In conclusion, the results have implications for shade tree species selection, monitoring of woody biomass and maintenance of biodiversity.

“…Some studies [e.g., Refs. 21 , 51 ] have demonstrated that tree density was the main biological variable affecting the H-DBH allometry of trees, while other studies [e.g., Refs. 52 , 53 ] reported that as basal increases, trees become shorter.…”

“…La especie M. tinctoria ("Dinde mora") es una especie que se caracteriza por ser pionera longeva en sucesiones secundarias, por sus diversos atributos ecológicos hacen de este árbol prioritario para ser utilizado en proyectos de reforestación [4]. Al hablar del fruto, en estado de madurez, contiene numerosas semillas aplanadas, de forma oblongo-elíptica, comprimidas, de 2 a 3 mm de largo, redondeadas en la base, oblicuas y de color café [5] aunque esta especie presenta un periodo corto de fructificación, produce anualmente una gran cantidad de frutos en épocas de lluvia, contribuyendo al abastecimiento de recursos y abundante alimentación durante este curso de tiempo [1].…”

Resumen. En procesos de restauración ecológica se hace necesario el suministro de plántulas nativas para alcanzar los objetivos de la restauración, en ese sentido estudiar la calidad física de las semillas resulta importante para garantizar la cantidad de material vegetal que se utilizará en proyectos de restauración ecológica. La especie Maclura tinctoria (L.) D. Don ex Steud, especie nativa en Colombia propagada por semillas, es empleada para la recuperación de suelos, construcción de cercas vivas y siembra en asocio con otros cultivos agrícolas. Teniendo en cuenta lo anterior, el presente estudio tuvo como objetivo evaluar tres tratamientos pre germinativos para M. tinctoria. El experimento se realizó en la ciudad de Cali, Colombia, el primer tratamiento pregerminativo consistió en someter las semillas a inmersión en extracto del jugo de semillas de Lens culinaris por 24 horas, el segundo tratamiento consistió en la inmersión en agua por 24 horas y finalmente el tratamiento sin inmersión el cual fue el tratamiento control. Fue realizado un análisis de varianza y prueba de Tukey al 95 %. Los resultados obtenidos muestran que las semillas de M. tinctoria bajo el tratamiento de inmersión en el jugo de Lens culinaris presentaron una mayor germinación representado en un 82.5 %. Además, se quiso evaluar el desarrollo y crecimiento de las semillas germinadas en cada tratamiento, con el objetivo de observar si los tratamientos influían en estos factores; para la recolección y análisis de datos se tuvieron en cuenta el número de hojas y la altura de cada plántula, y se evaluó también bajo un análisis de varianza y prueba Tukey, evidenciado a un 0.05 de significancia la altura con p-value de 0.796 y el numero de hojas a un p-value de 0.85; no presentaron diferencias significativas.
