Taxifolin 3-arabinoside from Fragaria x ananassa
Phytochemistry, 1995Abstract From the roots of Fragaria x ananassa, a new flavonoid, (+)-taxifolin 3-O-α- l -arabinofuranoside was isolated and its structure was established on the basis of chemical and spectroscopic evidence. A hydrolysable tannin, pedunculagin, and condensed tannins, (+)-catechin, (+)-afzelechin-(4α-8)-(+)-catechin, procyanidin B-3 and ...

Strawberry (Fragaria × ananassa)
2006Genetic transformation in strawberry (Fragaria spp.) can be achieved by using the Agrobacterium-mediated procedure on leaves from in vitro proliferated shoots. Regardless of the sufficient regeneration levels achieved from leaf explants of some commercial strawberry genotypes, the regeneration of transformed strawberry plants remains difficult and ...

Honeybee pollination of strawberries (Fragaria x ananassa Duchesne)
Australian Journal of Experimental Agriculture, 1988The pollination requirements of strawberries (Fragaria x ananassa Duchesne cv. Tioga) were examined in a planting in southern Victoria. Plots that were accessible to honeybees (Apis mellifera L.) had 20.8% marketable berries (well shaped, > 10 g fresh weight), whereas plots that were not accessible had only 4.5% marketable berries. The total numbers

Plant Regeneration from Strawberry (Fragaria x Ananassa) Mesophyll Protoplasts
Journal of Plant Physiology, 1988In vegetatively propagated species with strong heterozygoty and high ploidy levels, plant breeding through somatic cell genetics is of special interest. In strawberry breeding, where plant breeders wish to introduce specific traits such as earliness, winterhardiness and disease resistance into already established cultivars these techniques might be of ...

Fragaria x ananassa originated spontaneously in mixed plots of Fragaria virginiana P. Miller and Fragaria chiloensis (L.) P. Miller in horticultural areas in north west France and in some botanical gardens of Europe between circa 1715 and 1760. The hybridogenic origin and the octoploid level are the basis for a high variability of all important ...

Stabilisation of strawberry (Fragaria x ananassa Duch.) anthocyanins by different pectins
Food Chemistry, 2013The objective of the present study was to evaluate the effects of different pectins on strawberry anthocyanins in viscous model solutions at pH 3.0. For this purpose, low esterified amidated, low and high methyl esterified citrus and apple pectins, and a sugar beet pectin (SBP), respectively, were added to strawberry extracts.

Journal of Berry Research, 2012
The transmission of transgenes (uid-A and nptII) was studied in crosses between transgenic plants, with Fragaria x ananassa cultivar Teodora as the donor plant and various Fragaria species as recipient plants. GUS expression and kanamycin resistance were evaluated in embryos and in seedlings after aseptical germination, both in intra- and ...

Polyphenol production in hairy root cultures of Fragaria x ananassa
Phytochemistry, 1995Abstract Hairy roots of Fragaria × ananassa cv. Reikou, induced with Agrobacterium rhizogenes ATCC 15834, grew well in hormone-free Murashige-Skoog (MS), root culture and Gamborg B5 liquid media. Particularly, in MS medium, hairy roots whowed maximum growth (539 mg per flask, dry wt at week 8) producing high contents of polyphenols (especially (
