“…Based on the commercial weight, pineapple fruits can be classified into three categories: category A (>1.7 kg), category B (1.3-1.6 kg), and category C (<1.3 kg) [9]. In this light, the "Santa Rosa" ecotype fruits (in the three densities) and "Smooth Cayenne" cultivar fruits (at 55500 plants) were classified as grade A, while the remaining fruits of other treatments were classified as grade B. e average weight of the fruits harvested in this study was higher than the weight reported for "Golden" pineapple fruits grown at densities of 50000 (1.61 kg) and 70000 (1.51 kg) plants ha −1 [7], also exceeding the weight of "Smooth Cayenne" fruits (<1.64 kg) harvested from a cultivation system associated with cassava plants [14]. On the other hand, the results clearly show that yield is strongly influenced by sowing density, a factor that naturally enables a greater number of fruits to be harvested.…”

“…e records of the morphological characteristics of the pineapple plants reported in this study are lower than the values reached by "Queen" cultivar cultivated in three different ecosystems (freshwater peat, brackish peat, and alluvial soil), as they reached a height greater than 80 cm and D-leaf lengths over 65 cm [13]. e quantification of these morphological characteristics (including the number of leaves) is of great importance in pineapple cultivation because they are related to photosynthetic efficiency and fruit development [12][13][14].…”

Pineapple is a crop of great importance for the economic stability of a large number of Peruvians; however, in areas experiencing low degrees of technological intervention, farmers generally adopt low planting densities. The objective of this study was to determine the effect of three plantation densities (35700, 47600, and 55500 plants ha−1) on the agronomic performance and fruit quality of three pineapple cultivars (“Golden,” “Smooth Cayenne,” and “Santa Rosa” ecotype). The experiment was performed under a randomized complete block design (RCBD) in a factorial arrangement, and the data were subjected to analysis of variance and the Tukey test ( p < 0.05 ). The results show significant differences in terms of plant height and D-leaf length, with “Golden” being the cultivar that achieved the best performance at the three planting densities. The diameter (11.77–13.29 cm) and weight of the fruit without a crown (1.48–1.85 kg) were not affected by the treatments; in contrast, the length and weight of the fruit with a crown did exhibit significant variations, highlighting the “Smooth Cayenne” cultivar and “Santa Rosa” ecotype at a density of 55500 plants ha−1, respectively. The highest estimated yield (>100 t ha−1) for the three pineapple cultivars was recorded at a density of 55500 plants ha−1. The content of total soluble solids was higher in the “Golden” cultivar, but in general, all the fruits exceeded the established standards. Based on the results, it is recommended that farmers in the area and those with similar conditions establish a planting density of 55500 plants ha−1 because it improves the yield without damaging the quality of the fruit of the pineapple cultivars evaluated.

“…In the northern state of Acre, the out of season price per fruit can attain R$ 3.25 (US$ 1.50 approximately) or more depending on the size and quality of the fruit (AGRIANUAL, 2012;BAYMA et al, 2012). In this region, fruit mass may be up to 24.4% lower in full sun cultivation than fruit under shade (CUSTÓDIO et al, 2016).…”

“…Such intercropping systems offer ecological and economical advantages since they enhance biodiversity, increase land-use efficiency, improve soil covering and biomass recycling, and enable the commercialization of additional products. These factors serve to improve the food security and economical stability of family farmers (LUDEWIGS; BRONDIZIO, 2009;ARAÚJO NETO et al, 2014;CUSTÓDIO et al, 2016).…”

A alta temperatura e radiação solar das regiões tropicais podem queimar e reduzir o tamanho dos frutos do abacaxizeiro. Uma alternativa aos produtores dessa cultura é o sombreamento das plantas, proporcionando o condicionamento climático. Assim sendo, objetivou-se avaliar os efeitos do sombreamento sobre os teores de clorofilas, a morfologia e anatomia foliar e a produtividade do abacaxizeiro. O experimento foi realizado em condições de campo, em delineamento de blocos casualizados, com quatro repetições e cinco tratamentos de sombreamento: 0% (abacaxizeiro a pleno sol); 45,0% (cobertura com plantas de mandioca); 48,3% (cobertura com plantas de feijão-de-porco); 30 e 50% (cobertura com tela de sombreamento). As características anatômicas, histológicas e bioquímicas das folhas, juntamente com a produtividade e percentagem de abacaxis queimados, foram determinadas 16 meses após o plantio. Abacaxizeiros cultivados sob a sombra de feijão-de-porco ou mandioca mostraram plasticidade fenotípica, com as folhas “D” apresentando tricomas com menor comprimento e elementos de vasos com menor diâmetro. Sob a sombra da mandioca ocorreu aumento da espessura da epiderme abaxial, do parênquima clorofilado e densidade estomática e, enquanto que a espessura da hipoderme aquífera e a porcentagem de frutos queimados pelo sol foram reduzidas. Sob a sombra do feijão-de-porco, as espessuras do parênquima clorofilado, do mesofilo e da folha foram reduzidas. Não houve diferença significativa entre os tratamentos no que se refere à produtividade dos abacaxis, embora o sombreamento com tela e mandioca tenha produzido redução significativa de frutos queimados.

“…Otra observación en coincidencia con Montero et al (2017) es que el ambiente lumínico tuvo un efecto indirecto sobre la reproducción: las plantas de B. serra ubicadas en áreas más expuestas fueron más pequeñas y, por consiguiente, tuvieron infrutescencias más pequeñas. Un patrón similar se observó en A. comosus, que tuvo menor rendimiento, menor tamaño de fruto promedio y mayor porcentaje de frutos quemados por el sol en monocultivos que cuando se realizó cultivo intercalado con mandioca, que le hizo sombra (Custódio et al 2016). Para otras especies existen patrones diferentes según el área de estudio.…”

RESUMEN.Las bromeliáceas terrestres son comunes en los bosques neotropicales. En particular, en el sotobosque de los quebrachales chaqueños existen parches densos de Bromelia serra, que crecen bajo condiciones microambientales heterogéneas. El ambiente lumínico afecta la asignación de biomasa a distintos órganos, por lo que las plantas que crecen bajo distintas condiciones lumínicas presentan una arquitectura diferente. A su vez, el tamaño de la planta y los factores ambientales y genéticos condicionan la asignación de biomasa a los caracteres reproductivos. Para evaluar el efecto del ambiente lumínico sobre los caracteres vegetativos y reproductivos se seleccionaron cuatro parches en cada uno de tres sitios separados por 500 m, en un quebrachal de la Cuña Boscosa Santafesina. En cada parche se seleccionaron cuatro plantas adultas. A cada planta se le midió la altura, el diámetro, la longitud y el ancho de la hoja más larga, el diámetro de la infrutescencia, el número, el peso y el tamaño de los frutos y el número de semillas. La caracterización de la apertura del dosel sobre cada planta se hizo con fotografía hemisférica. Los Modelos Lineales Generales Mixtos muestran que el porcentaje de la varianza explicado por la variación espacial (factores aleatorios representando a los sitios y a los parches) es mayor para caracteres vegetativos que para reproductivos. La mayor proporción de esta varianza se registró a nivel de parche para los caracteres vegetativos y a nivel de sitio para los reproductivos. Mediante un Modelo de Ecuaciones Estructurales basado en Modelos Lineales Generales Mixtos se determinó que el ambiente lumínico afecta de forma directa e indirecta el diámetro de la infrutescencia. Las plantas expuestas a mayor apertura de dosel son más pequeñas y tienen menor cantidad y tamaño de frutos. Esto resulta en infrutescencias más chicas, lo cual destaca el efecto indirecto del ambiente lumínico sobre los caracteres reproductivos.[Palabras clave: apertura del dosel, asignación de biomasa, Bromeliaceae, plasticidad fenotípica, quebrachal] ABSTRACT. Vegetative and reproductive traits of Bromelia serra (Bromeliaceae): Variations at different spatial scales and light environment effects. Terrestrial bromeliads are common in neotropical forests, particularly in the understory of the Chaco woodlands, where there are dense patches of Bromelia serra growing under heterogeneous micro-environmental conditions. The light environment affects the allocation of biomass to different organs and, thus, plants that grow under different light conditions have different architecture. Furthermore, the allocation of biomass to reproductive structures is conditioned by plant size, as well as by environmental and genetic factors. To evaluate the effect of light environment on the vegetative and reproductive traits, four patches were selected from three sites separated by 500 m in the Cuña Boscosa Santafesina. At each patch, four plants were selected. Height, diameter, length and width of the longest leaf, the diameter of the infruc...
