abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...

In Florida, 7,100 acres of fresh strawberries (Fragaria ×ananassa Duch.) were planted in fields during the 2003–04 growing season using polyethylene mulch raised beds and drip irrigation. Florida is the second largest fresh market strawberry-producing state behind California. Because Florida enters the market prior to California during the winter months, Florida strawberry value per pound excee...

Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...

The gene encoding stilbene synthase is frequently used to modify plant secondary metabolism with the aim of producing the self-defence phytoalexin resveratrol. In this study, strawberry (Fragaria x ananassa) was transformed with the NS-Vitis3 gene encoding stilbene synthase from frost grape (Vitis riparia) under the control of the cauliflower mosaic virus 35S and the floral filament-specific fi...

Two genomic clones corresponding to putative pectate lyase genes (plA and plB) were isolated and characterized in strawberry (Fragaria x ananassa cv. Chandler). The corresponding ORFs for the plA and plB genes revealed deduced proteins of 451 and 439 amino acids, respectively, that differ from that of the previously isolated strawberry plC gene. Southern blot analysis has shown that while the p...

Fragaria orientalis is the most distributed wild strawberry in North Asia, and it consumed large quantities by local population. However, poor knowledge of chemical composition, metabolic profiles, bioactivity leads to insufficient use F. beyond region. The aim our study was investigate nutritional value, sensory parameters cultivated fruits, before during postharvest storage. Sixty-five compou...

Understanding the nature of pathogen host interaction may help improve strawberry (Fragaria × ananassa) cultivars. Plant resistance to pathogenic agents usually operates through a complex network of defense mechanisms mediated by a diverse array of signaling molecules. In strawberry, resistance to a variety of pathogens has been reported to be mostly polygenic and quantitatively inherited, maki...

Using cDNA microarrays, a comprehensive investigation of gene expression was carried out in strawberry (Fragaria x ananassa) fruit to understand the flow of events associated with its maturation and non-climacteric ripening. We detected key processes and novel genes not previously associated with fruit development and ripening, related to vascular development, oxidative stress, and auxin respon...
