Tomato fruit growth and composition depend on both genotype and environment. This paper aims at studying how fruit phenotypic responses to changes in carbon availability can be influenced by genotype, and at identifying genotype-dependent and -independent changes in gene expression underlying variations in fruit growth and composition. We grew a parental line (Solanum lycopersicum) and an intro...

Pepino (Solanum muricatum Aiton), also known as melon-pear, is a vegetatively propagated vegetable crop grown for its juicy and aromatic fruit. Great variation in fruit weight, shape, and color can be found among cultivars of pepino (Anderson et al., 1996; Heiser, 1985). Despite being an important crop in Pre-Columbian times in the Andean region, it has not achieved the same relevance as other ...

The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old ‘Summit’ and ‘Hedelfinger’ trees on rootstock Gisela 5 in Fruit Growing centre Gačnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, th...

BACKGROUND AND AIMS Fruit set in indeterminate plant species largely depends on the balance between source and sink strength. Plants of these species show fluctuations in fruit set during the growing season. It was tested whether differences in fruit sink strength among the cultivars explained the differences in fruit-set patterns. METHODS Capsicum was chosen as a model plant. Six cultivars w...

The cell expansion phase contributes in determining the major characteristics of a fleshy fruit and represents two-thirds of the total fruit development in tomato (Solanum lycopersicum). So far, it has received very little attention. To evaluate the interest of a genomic scale approach, we performed an initial sequencing of approximately 1,200 cell expansion stage-related sequence tags from tom...

CO, exchange rates per unit dry weight, measured in the field on attached fruits of the late-maturing Cal Red peach cultivar, at 1200 nmol photons m s ' and in dark, and photosynthetic rates, calculated by the difference between the rates of CO, evolution in light and dark, deelined over the growing season. Caleulated phetosynthetic rates per fruit increased over the season with increasing frui...

This study examined how forest edges, fruit display size, and fruit colour influenced rates of seed dispersal in an endemic, bird-dispersed, New Zealand mistletoe species, Alepis flavida. To examine rates of seed dispersal, fruit removal rates were compared between plants growing on forest edges and in forest interior, and also between two morphs of plants with different coloured fruits. Two as...

The aim of this study was to evaluate the effects of foliar application of boron and calcium on postharvest storage characteristics of Asian pear (Pyrus pyrifolia) fruit. This experiment was carried out in the experimental orchard of Asian pear at Tarbiat Modares University, Tehran, Iran. The treatments were two concentrations of boric acid (0% and 0.5%) and three concentrations of calcium chlo...
