Plant architecture influences gall abundance in a tropical montane plant species Acta Botanica
Boaventura,Maria Gabriela; Pereira,Cássio Cardoso; Cornelissen,Tatiana.
ABSTRACT Sessile and host-specific herbivores, such as gall-inducing insects, are usually patchily distributed within the populations of their host plants, and it has been suggested that both inter- and intra-plant variation affect gall abundance, distribution and survivorship. Variation in plant traits, such as size and architecture, has been previously demonstrated as a determinant of gall distribution. We examined the influence of architectural complexity of the tropical plant Galianthe brasiliensis (Rubiaceae) on the abundance of the stem-galler Lopesia sp. (Diptera, Cecidomyiidae) along an elevation gradient where both insect and plant were distributed. A total of 120 plants were sampled along the gradient and more than 580 galls were counted, while...

Strawberry yield submitted to different root pruning intensities of transplants Rev. Bras. Frutic.
Cocco,Carine; Ferreira,Letícia Vanni; Gonçalves,Michél Aldrighi; Picolotto,Luciano; Antunes,Luis Eduardo Corrêa.
This study aimed to evaluate the growth of plants and the precocity of strawberry production under different root pruning intensities at planting time. Bare roots plants with 12 millimeters crown diameter produced in nurseries from the Patagonia region, Argentina were used. The planting was carried out on May 12th 2010 into experimental plots with non-fumigated soil. The treatments consisted of three cultivars (Camarosa, Florida Festival and Camino Real) and three pruning intensities (1/3, 2/3 and no pruning) on the total root length of the plants. The experimental design used was a randomized block design in a 3x3 factorial arrangement with three replications and 12 plants per plot and density of 11.1 plants m-2. Mature fruits were harvested from July...

Effects of early fertilization on the performance of Nothofagus dombeyi planted in the Coastal Range of south-central Chile Ciencia e Investigación Agraria
Donoso,Pablo J; Soto,Daniel P; Schlatter,Juan E; Büchner,Carlos A.
Native Nothofagus dombeyi growth rates excel in secondary forests and in some plantations, and the species has good timber quality. However, few have reported on the effects of fertilization on N. dombeyi plantations. This is a key matter since fertilization has environmental and financial costs, and therefore its use to increase growth and survival for production or restoration must be carefully evaluated. Here we evaluated the early effects of fertilization (control and three levels) using several performance variables (leaf properties, growth, plant quality, and survival) in a N. dombeyi plantation at a low elevation in the Coastal Range of south-central Chile, which has a rainy temperate climate and medium fertility soils. Four years after plantation...

Capacidad de multiplicación, productividad e indicadores de calidad de consumo de nuevas variedades mexicanas de fresa. Colegio de Postgraduados
Rodríguez Bautista, Geremias.
El presente trabajo tiene el objetivo de evaluar la capacidad de multiplicación, productividad e indicadores de calidad de consumo de las variedades mexicanas (CP-Jacona y CP-Zamorana) y extranjeras (Festival y Albion) de fresa. En comparación con las variedades mexicanas, ´Festival´ presentó mayor número de estolones, coronas y plantas hijas en el vivero de Zirahuén; sin embargo, el contenido de almidón fue mayor en las variedades mexicanas. En el vivero Tanaquillo, ´Festival´ y ´CP-Jacona´ presentaron mayor número de plantas hijas, aunque, el contenido de almidón fue mayor en ´Festival´ que en ´CP-Jacona´. En Zirahuén, la acumulación de almidón en plantas hijas fue mayor, en contraste, con el vivero Tanaquillo donde el número de plantas hijas fue mayor....
