Concentrations of the macronutrients (K, Ca, Mg, Na, P and S) and micronutrients (Fe, B, Zn, Mn and Cu) in whole fruit, pulp, rind and albedo of fruit from young and mature 'Bellamy' navel orange trees were measured at fortnightly intervals during fruit development. The general order of abundance of the macronutrients were K > Ca > Mg ˆ P > S > Na and the abundance of the micronutrients followe...

In this study, the authors evaluated the effectiveness of the Energize Your Life! social-marketing campaign pilot study to improve knowledge, attitudes, and fruit intake among community college students. The authors used a cross-sectional, quasi-experimental, pre- and posttest design. They randomly selected community college students (N = 1,367) and exposed the intervention campus to fruit fair...

Auxin is one of the most prominent phytohormones regulating many aspects of fleshy fruit development including fruit set, fruit size through the control of cell division and cell expansion, and fruit ripening. To shed light on the role of auxin fruit ripening, we have previously shown that Sl-ARF4 is a major player in mediating the auxin control of sugar metabolism in tomato fruit (cv MicroTom)...

We applied a semi-mechanistic model of fresh matter accumulation to peach fruit during the stage of rapid mesocarp development. The model, which is based on simple hypotheses of fluid flows into and out of the fruit, assumes that solution flow into the fruit increases with fruit weight and transpiration per unit weight, and decreases with the maximum daily shrinkage of the trunk, which was used...

Rhagoletis juglandis Cresson is a specialist that deposits its eggs into the husks of developing walnut fruit. Like other walnut infesting ßies in the R. suavis group, R. juglandis actively superparasitizes its larval hosts. However, little is known regarding the degree to which hosts are reused and the ecological context under which host reuse occurs. This Þeld study examined the pattern of ho...

Plant species that bear fruit often utilize expansion of an ovary (carpel) or accessory tissue as a vehicle for seed dispersal. While the seed(s) develop, the tissue(s) of the fruit follow a common progression of cell division and cell expansion, promoting growth of the fruit. Once the seed is fully developed, the fruit matures and the surrounding tissue either dries or ripens promoting the dis...

Three bunches of unripe ‘Williams’ banana fruit of different maturity, 173, 156 and 71 days from bunch emergence, were harvested. Fruit from the top, bottom and middle hands from each bunch were fumigated for 24 h with 1-methylcyclopropene (1-MCP) at 0, 5, 50 or 500 nl l at 20C. All fruit were then stored at 20C in air containing 0.1 ml l ethylene and the time taken for each fruit to ripen (gre...

The prevalence of overweight is increasing dramatically in children. A protective factor against the development of overweight is a sufficient intake of fruit and vegetables. However, the consumption of fruit and vegetables in children is far from ideal these days. Therefore, it is important to examine how the intake of fruit and vegetables can be promoted. In this study, the effects of two fru...

Fruit size regulation was studied in the apple cultivar 'Gala' and a large fruit size spontaneous mutant of 'Gala', 'Grand Gala' (GG). GG fruits were 15% larger in diameter and 38% heavier than 'Gala' fruits, largely due to an increase in size of the fruit cortex. The mutation in GG altered growth prior to fruit set and during fruit development. Prior to fruit set, the carpel/floral-tube size w...
