Throughout tomato domestication, a large increase in fruit size was associated with a loss of dry matter and sugar contents. This study aims to dissect the contributions of genetic variation and the physiological processes underlying the relationships between fruit growth and the accumulation of dry matter and sugars. Fruit quality traits and physiological parameters were measured on 20 introgr...

Definitions There are many, sometimes confusing, terms used in the literature. Simple carbohydrate (sugar) refers to monoand disaccharides; complex carbohydrate refers to polysaccharides such as starch. Common disaccharides are sucrose (glucose fructose), found in sugar cane, sugar beets, honey, and corn syrup; lactose (glucose galactose), found in milk products; and maltose (glucose glucose), ...

The density of unripe kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson cv. Hayward) early in storage was investigated as a means of determining the current fruit dry matter (DM) and total sugar-plus-starch concentrations, and of predicting DM and soluble solid concentrations later when the fruit had ripened. To investigate the robustness of the density relationships with DM...

In implementing the integrated pest management mango (Mangifera indica L.) program using weaver ants (Oecophylla smaragdina F.) as a major component in the Northern Territory of Australia, we received a number of questions from farmers and extension officers asking whether weaver ant marks reduce internal fruit quality and induce fruit rot, which is economically important. However, this issue h...

Quality characteristics of tomato fruit will be affected by a number preand post harvest factors. In this study, the effect of maturity stage on post harvest quality characteristics of tomato was investigated. Tomato fruits of the same farmers‟ variety were harvested at mature-green, medium ripe and full-ripe stages. After harvesting, tomato samples were sliced and homogenized in blender for pr...

Compositional changes that occur during fruit development affect both the organoleptic and nutritional quality of small fruit. Compositional changes in blueberry (Vaccinium corymbosum L) and cranberry (Vaccinium macrocarpon Aiton) fruit were determined at 3 maturities (white, turning and fully colored) during 2 seasons by analyzing sugar, acid, total phenolic, and total anthocyanin composition,...

Overall climatic effects on citrus fruit quality have been well-documented and are discussed by W. Reuther in his section on "Climate and Fruit Quality". These can be briefly summarized as higher sugar levels and lower acidity in humid areas with warm nights. Conversely, sugar levels tend to be lower and acidity higher in arid areas with cool nights. Such generalizations often vary when shorter...

Since an investigation of the various sugars present in winter pears was in progress at this station, it was thought desirable to determine in a preliminary way the variation in the sugar content of the various portions of the fruit, and from this information to decide as to the best method of taking samples of the pear. The effort was made to divide the fruit into natural regions on the basis ...
