“…These plants formed a higher amount of flower differentiated buds and reached a more developed phase of the terminal inflorescence. This behavior is consistent with the early arrest of growth and with the hypothesis that reproductive induction takes place when the growth rate of the apex slows down [15].…”

“…They can be applied as controlled abiotic stress to enhance the reproductive behavior of the plants [13,14], acting on the growth rate. As a consequence, plant architecture and quality can be strongly influenced [15], especially in nursery cultivation. The nutrient level in particular has been reported to influence the growth and architecture of the plant.…”

BACKGROUND: Flower induction and the reproductive and vegetative behavior of strawberry plants depend on several agronomic and nutritional factors. OBJECTIVE: During propagation in the nursery, several fertigation techniques (nutrient amount and timing), rooting times and pot sizes were used to modify plant architecture. METHODS: Different levels of nutrient applications were tested by setting the fertigation composition at 700 or 1000 Scm −1 electrical conductivity. Fertigation was continuous, delayed or temporary during the summer growth of Elsanta and Capri runner plants, for tray and mini-tray plant production. Early and late rooting dates were also compared. RESULTS:The experiments showed the effects of the container type (tray and mini-tray) and the nutritional level on the plant architecture and reproductive behavior, with a major control of plant growth. Rooting time and fertigation timing also had some effects on plant architecture. CONCLUSIONS: Propagation and fertigation techniques can become effective strategies for manipulating the architecture and the reproductive behavior of the plant. However, the interaction between many growing factors and plant growth may reduce the predictability of the effects.

“…There is some work on the architecture of the strawberry, focused on the description of plant development and the appearance of fruits for different varieties (Savini and Neris, 2003;Bosc et al, 2012) and crop conditions (Savini et al, 2005); however the results are shown in a schematic or parametric form, but without making a realistic threedimensional representation of the plant.…”

ResumenLos doseles virtuales se utilizan en modelos ecofisiológicos para estudiar el funcionamiento de las plantas. El propósito de este trabajo fue desarrollar un modelo informático para construir doseles virtuales de plantas de fresa y evaluar la habilidad de éstos para simular la radiación interceptada (aproximada con la fracción de huecos), fundamental para los procesos de fotosíntesis y transpiración. El modelo representa cada planta como un conjunto de hojas, a partir de la superficie promedio de su foliolo central, el número promedio de hojas por planta y la geometría de plantación. La relación entre las dimensiones de los foliolos y el pecíolo siguen funciones normales de distribución, ajustadas con datos de campo. Los datos se obtuvieron en tres áreas de muestreo de 1 m 2 , de una parcela de producción, donde las hojas se midieron en cuatro tiempos para simular diferentes densidades de vegetación. Simultáneamente, se tomaron fotografías desde ángulos de iluminación de 0 o , 15 o y 30 o , para medir la fracción de huecos cerca del nadir, para estimar la luz interceptada por las hojas alrededor del mediodía solar. Se utilizó el modelo para construir doseles virtuales equivalentes a los medidos en campo. Se calcularon correlaciones lineales entre la fracción de huecos (desde cada ángulo de iluminación) de los doseles reales (fotografías) AbstractVirtual canopies are used in ecophysiological models to study how plants work. The purpose of this work was to develop a computer model to build virtual canopies of strawberry plants and evaluate the ability of these to simulate intercepted radiation (approximated with the void fraction), fundamental to the processes of photosynthesis and transpiration. The model represents each plant as a set of sheets, from the average surface of its central leaflet, the average number of leaves per plant and planting geometry. The relationship between the size of leaflets and petiole follow normal distribution functions, adjusted with field data. Data was collected in three sampling areas of 1 m 2 , in a plot of production, where leaves were measured four times to simulate different densities of vegetation. Simultaneously, photographs were taken from illumination angles at, IntroducciónEl modelado consiste en representar el funcionamiento de un sistema bajo la forma de un conjunto de leyes matemáticas que describen sus componentes más importantes, así como las interacciones entre ellos. En el caso de una planta, los componentes representados son los que intervienen en el desarrollo (leyes arquitecturales y fenología), el crecimiento (aumento y distribución de biomasa) y la producción (los frutos), así como los mecanismos a través de los cuales la planta interactúa con el medio ambiente (en particular, los efectos del clima, de la disponibilidad hídrica y de la nutrición mineral) (Thornley y Johnson, 2000).El modelado de plantas comenzó en los años 1950, con de Wit (1958). En los años 1960-1970 se desarrollaron los primeros modelos suelo-planta-atmósfera (Hanks, 1974). En los añ...
