Plots of 19 clones of strawberry (Fragaria ×ananassa Duch.) were planted in 1996. Fruit of 16 clones were harvested in 1997 and fruit of 11 of the same clones plus three additional clones in 1998. Individual plots were harvested on three or four dates in 1997 and from three to seven dates in 1998. Fruit firmness was determined with a penetrometer at harvest, and additional samples were processe...

Epidemiological studies suggest that consumption of fruit rich in phenolic compounds is associated with health-protective effects due to their antioxidant properties. For these reasons quality evaluation has become an important issue in fruit industry and in breeding programs. Phytochemical traits such as total phenolics, flavonoids, anthocyanins, L-ascorbic acid, sugar content and relative ant...

‘Pink Lady’ apple fruit were evaluated for anti-oxidative stress at various stages of fruit maturity and ripening. Fruit were harvested at weekly intervals starting 7 days before anticipated commercial harvest up to 42 days after commercial harvest (DACH), and then fruit harvested at commercial maturity were allowed to ripen at 22 ± 0.5C for 20 days. Ethylene production and respiration rate inc...

introduction: fruits and vegetables have special importance as a very important part of the human food supply. and from the beginnings of life, man has used these products to supply a part of his food. nowadays, horticultural products are widely used in the diet. cherry is one of the deciduous trees in the temperate regions, which is potassium rich. use of oxalic acid significantly reduces fros...

A breeding program searching for new peach and nectarine varieties adapted to the Ebro Valley growing conditions is being developed at the Aula Dei Experimental Station (CSIC). This program evaluates 15 populations obtained by controlled crosses. Different agronomic parameters such as blooming date, yield, and ripening date were determined in these populations. Quality traits such as fruit type...

Studies were designed to examine the effects of host plants (apple, Malus domestica Borkh., and peach, Prunus persica L.) on the development of oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae). Oriental fruit moth larvae developed faster on peach than on apple, both on fruit as well as on growing terminal shoots. On fruit, these differences were shown to cause signific...

Much of the cost associated with marker discovery for marker assisted breeding (MAB) can be eliminated if a diverse, segregating population is generated, genotyped, and made available to the global breeding community. Herein, we present an example of a hybrid, wild-derived family of the octoploid strawberry that can be used by other breeding programs to economically find and tag useful genes fo...

to study the relationship between some morphological, phonological and early flowering (reduced juvenile phase) characters during some different growing seasons, a study was performed on apple seedling populations obtained from controlled crosses. some qualitative as well as quantitative traits were assessed in more than 400 progenies from four populations of crosses between ‘golab-e kohanz’ an...
