Blueberry (Vaccinium spp.) fruit consumption has increased over the last 5 years, becoming the second most important soft fruit species after strawberry. Despite the possible economic and sensory impact, the blueberry volatile organic compound (VOC) composition has been poorly investigated. Thus, the great impact of the aroma on fruit marketability stimulates the need to step forward in the und...

organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. one of these compounds is humic acid that was used widely in research and commercial programs. humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. in order to inves...

The role of polygalacturonase (PG) in the development, ripening, and softening of fruit from two strawberry cultivars with different flesh firmness and softening characteristics was compared. Changes in PG activity and gene expression during development, ripening and softening were measured. The PG genes from each cultivar were cloned and analyzed, and were classified with other PG genes using ...

2,5-Dimethyl-4-hydroxy-3(2H)-furanone (furaneol) is an important aroma compound in fruits, such as pineapple and strawberry, and is reported to contribute to the strawberry-like note in some wines. Several grapevine species are used in winemaking, and furaneol is one of the characteristic aroma compounds in wines made from American grape (Vitis labrusca) and its hybrid grape. Furaneol glucoside...

BACKGROUND Strawberry (Fragaria x ananassa) is an economically important soft fruit crop with polyploid genome which complicates the breeding of new cultivars. For certain traits, genetic engineering offers a potential alternative to traditional breeding. However, many strawberry varieties are quite recalcitrant for Agrobacterium-mediated transformation, and a method allowing easy handling of l...

Strawberry (Fragaria x ananassa Duch.) production in Florida is the second largest in the U.S. after California, with about 3360 hectares and gross sales over $330 million. Florida is the largest supplier of strawberries during the winter months in the U.S. and the majority of the strawberry production occurs in the west central part of the state. Strawberry yields in Florida have increased ove...

The flowering phenology of six genetically distant strawberry cultivars (‘Candonga®’ (ES), ‘Clery’ (IT), ‘Florence’ (UK), ‘Frida’ (NO), ‘Gariguette’ (FR), and ‘Sonata’ (NL)) was studied for 3 years in relation to climatic parameters open-field cultivation at three locations (Norway, Poland, Germany) soil-less two (Italy, France), covering a distance 16 degrees latitude. This proved be useful ap...

In this study, cell-suspension culture of strawberry (Fragaria × ananassa), cultivars Camarosa, and Sweet Charlie has been established. Embryogenic callus was induced by incubating the in vitro juvenile leaf explants on medium, containing 2-mg/l picloram at dark. Suspension culture was initiated from 4-week-old embryogenic calli in the liquid MS medium with 1-mg/l 2,4-D and 2-mg/l picloram. Sus...

Schon seit lfingerer Zeit befasst sich die Forschergruppe, der auch der Autor angeh6rt, mit der Untersuchung der Beeinflussung yon Organellstrukturen in Hefe durch verschiedene Kulturbedingungen. Insbesondere interessieren uns die Ver~inderungen beim Ubergang von totaler Anaerobiose zu aeroben Bedingungen. Die durch entsprechende Versuchsanordnung erzielte gute Synchronisierung der Kulturen erl...
