Five strawberry (Fragaria × ananassa Duch.) cultivars were grown in Queensland, Australia to determine whether higher temperatures affect production. Transplants planted on 29 April and data collected growth, marketable yield, fruit weight the incidence of small less than 12 g until 28 October. Additional soluble solids content (SSC) titratable acidity (TA) from 16 September Minimum 2 °C 4 long...

Bacterial angular leafspot disease (BALD) of cultivated strawberry, caused by the bacterium Xanthomonas fragariae, has become an increasingly serious disease problem. It is of particular concern because it is readily transmitted through asymptomatic nursery plants. Until now, there have been no sources of resistance to this pathogen identified in either commercial varieties or germplasm. We hav...

Compost as a soil supplement significantly enhanced levels of ascorbic acid (AsA) and glutathione (GSH) and ratios of AsA/dehydroascorbic acid (DHAsA) and GSH/oxidized glutathione (GSSG) in fruit of two strawberry (Fragaria x ananassa Duch.) cultivars, Allstar and Honeoye. The peroxyl radical (ROO(*)) as well as the superoxide radical (O(2)(*)(-)), hydrogen peroxide (H(2)O(2)), hydroxyl radical...

Genetic transformation studies were carried out to standardize a protocol for Agrobacterium -mediated genetic transformation of three economically important strawberry (Fragaria x ananassa Duch) cultivars Kurdistan’, Camarosa’, and ‘Paros’. Shoot regeneration frequency 72, 65 and 30% was obtained on MS (1) basal medium supplemented with 2% glucose and 4 mg/l TDZ for Camarosa, Kurdistan and Paro...

A complex mixture of hundreds of substances determines strawberry (Fragaria x ananassa) aroma, but only approximately 15 volatiles are considered as key flavour compounds. Of these, 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) is regarded as the most important, but it is methylated further by FaOMT (Fragaria x ananassa O-methyltransferase) to 2,5-dimethyl-4-methoxy-3(2H)-furanone (DMMF) during ...

Glycosidically bound compounds have been identified in a vast number of fruits. They have been extensively studied in the cases of grapes and wines (Williams et al., 1980, 1982 a, b; Strauss et al., 1988; Gunata et al., 1990 a, b; Roscher, Winterhalter, 1993; Baumes et al., 1994; Sefton et al., 1994) and for other fruits such as mangoes (Adedeji et al., 1992), peaches (Krammer et al., 1991; Sum...

We genotyped strawberry cultivars by two newly selected and two previously reported SSR markers. All four markers produced interpretable electropherograms from 75 accessions consisting of 72 Fragaria × ananassa cultivars or lines and three octoploid Fragaria species accessions. These SSR markers were highly polymorphic; in particular, one of the newly developed markers, FxaHGA02P13, was capable...

Background: An essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. Objective: Cumin (Cuminum cyminum L.) Essential Oil (CEO) was analyzed to determine oil component. Antifungal effect of CEO was determined by in vitro technique. In second stage, effect of different concentrations of CEO by PDM on postharvest life of strawberry (Fr...

The effects of daylength and temperature on flowering of the cultivated octoploid strawberry (Fragaria × ananassa Duch.) have been studied extensively at the physiological level, but information on the molecular pathways controlling flowering in the species is scarce. The flowering pathway has been studied at the molecular level in the diploid short-day woodland strawberry (F. vesca L.), in whi...

Bare root transplants of strawberry (Fragaria x ananassa Duch. cv. ‘Selva’) were transferred to nutrient solutions with or without iron (Fe). After six weeks of growth, plants in the solution without Fe were chlorotic and had morphological changes in roots typical of Fe deficiency. At this point, four treatments were imposed with three replicates (plants) each: plants always grown without Fe (F...
