“…Citharexylum myrianthum does not have the same degree of specialization for water deficits between the trunk and roots, with the roots being more sensitive to drought than the trunk; i.e., this species does not tolerate water deficit conditions, requiring silvicultural treatments, such as those related to the irrigation [25]. The low adaptability of C. myrianthum has been corroborated in nearby areas at the site of study [16,26,27]. In addition, the survival rate of this species is reduced as the size of the container decreases [28].…”

Forest restoration in Brazil has gained relevance in the country’s environmental agenda, due to the need for forest recovery of large liabilities of existing forests and participation in several international vegetation restoration agreements. However, forest restoration management faces challenges, it being necessary to create a database of species-level performances to increase the success of these projects. The objective was to evaluate the survival and growth of five Atlantic Forest native species (Anadenanthera macrocarpa; Ceiba speciosa; Cytharexyllum myrianthum; Hymenaea courbaril; and Peltophorum dubium) in plastic bags (1177 cm3) and tubes (180 cm3). Ninety seedlings (18 of each species) were planted per container. Plant performance in the field consisted of evaluating the increase in the diameter and height of seedlings of the native forest species. Diameter at soil level (DSL) and plant height (H) were measured at 42 months after transplanting, and the monthly periodic increments (MPI) of the DSL and H were calculated. Plant survival (SV) of seedlings was affected by the type of container, registering the highest SV rates in those planted in plastic bags. Cytharexyllum myrianthum and H. courbaril presented high SV rates in tubes. The growth rate of the species at 42 months differed according to the containers tested. Cytharexyllum myrianthum presented the lowest SV rates (16.7–27.8%), regardless of the container used in this experiment. Ceiba speciosa was sensitive to the reduction in size of the container, showing low SV in tubes (27%) compared with plastic bags (61%); i.e., this species did not tolerate conditions with root growth restriction. Anadenathera macrocarpa and H. courbaril showed no differences in SV, regardless of the container used. The results assist the production of native species of the Atlantic Forest, reinforcing the need to understand performances in the field at the species level.

“…The A. macrocarpa (Fabaceae) has a high tannin composition in its bark and is used as a herbal medicine (ARAÚJO et al, 2018) for treatment of respiratory and inflammatory diseases and healing processes (FIGUEREDO et al, 2013). This species also contributes to the recovery of degraded areas by providing rapid carbon removal and triggering important environmental roles in landscape restoration (MORAIS-JUNIOR et al, 2020). The P. moniliformis (Fabaceae) has a high content of antioxidants that fight cancer cells (ALVES et al, 2014) and stands out among the main tree species in the Caatinga for the supply of honey (JESUS et al, 2015).…”

Trees of the Fabaceae family can produce seeds with contrasting size and germinative performance depending on the region where they were formed in the fruit. Such differences reduce the physiological quality of the seed lot. Thus, the aim of the present study was to evaluate the physiological quality of seeds formed in different seminal nucleus of the fruits of Anadenanthera macrocarpa and Pityrocarpa moniliformis and their implications for the final composition of the seed lot. The biometric characterization of the fruits was performed with four quantitative descriptors (length, width, thickness, and number of seeds per fruit). Then, seeds formed in seminal nucleus of the proximal, intermediate, and distal regions of the fruit were measured (length, width, and thickness) and evaluated using germination and vigor tests (germination speed, length, and dry weight of seedlings). Seeds from these species have biometric differences depending on their origin in the fruit, in which those formed in the seminal nucleus of the intermediate region of the fruit are larger than the other ones. The origin of the seeds of A. macrocarpa and P. moniliformis formed in different seminal nucleus of the fruit do not show differences in physiological quality. Therefore, the sorting of seeds originated in different regions of the fruit does not benefit the final quality of the seed lots of these species.

Sr. Editor: Se ha leído el artículo “Almacenamiento de carbono en sistemas agroforestales cafetaleros en las provincias de Jaén y San Ignacio, Cajamarca”, Vol. 4 Núm. 1 (2016). Menciona que para estimar la cantidad de biomasa viva se usó el método directo e indirecto a través de la extracción y fragmentación de sus componentes y haciendo uso de ecuaciones alométricas establecidas. Sin embargo, existen omisiones en la descripción metodológica del manuscrito: No indica la metodología seguida para el establecimiento de las parcelas, tampoco cómo se realizó la medición de las variables dasométricas de los árboles del Sistema Agroforestal (SAF) y de los arbustos de cafeto. Al respecto Negash et al. (2013) ajustaron ecuaciones alométricas para estimar biomasa aérea de café y, entre otras variables, el diámetro en los arbustos de café fue medido a una altura de 40 cm. Obvia el procedimiento para determinar el peso de materia seca y posterior ajuste de modelos, tampoco de alguna metodología de referencia, pese a la existencia de importantes fuentes como Soares et al. (2012), Picard et al. (2012), Nath et al. (2017) o Criollo et al. (2020). En la ecuación para estimar consideramos que falta incluir el área de la parcela, para poder extrapolar el valor de parcela a valores por hectárea. Debiendo ser la expresión correcta de la ecuación: , en la cual el término determina el valor de la biomasa en toneladas (t) (Cordero S., 2019) y el término el equivalente en hectáreas (ha) (Campos & Leite, 2017). El ajuste de las ecuaciones alométricas para estimar el contenido de carbono fue generado en un programa, pero no lo mencionan. Utilizan modelos de una sola variable, siendo uno de los modelos más utilizados para determinación de Volumen, Biomasa e incluso Carbono de los diferentes componentes de árboles y arbustos el modelo de Schumacher-Hall en el que Y es la variable dependiente, D y H corresponden al diámetro y altura de los árboles respectivamente (Akindele & LeMay, 2006; de Morais Junior et al., 2020). Sólo se utilizó diámetro por existir estudios que demuestran que el diámetro es la variable de mejor ajuste, descartando el propio análisis de los resultados, cuya mejor ecuación obtiene un de 0.191; es decir, la ecuación seleccionada explica menos del 20 % de la varianza de la biomasa aérea del café, muy desfavorable para este tipo de estudios, pues las ecuaciones con mejor calidad de ajuste son aquellas cuyo es próximo a uno (Picard et al., 2012; Batanero et al., 2017). Con relación al cálculo del carbono en las especies del componente arbóreo del SAF, no se especifican las ecuaciones utilizadas. En la ecuación descrita para calcular el porcentaje de carbono en el suelo no habría necesidad de hacerla depender de la ecuación que permite calcular el porcentaje de materia orgánica, puesto que ambas ecuaciones dependen del volumen gastado del testigo, volumen gastado de la muestra y el peso de la muestra.
