| nitrogen availability drives the effect of glomus intraradices on the growth of strawberry (fragaria x ananassa duch.) plants. | on the one hand, the critical nitrogen (n) content curve allows the minimal n content necessary for maximum growth rate at any stage of crop development to be predicted. on the other hand, arbuscular mycorrhizal fungi (amf) transfer n from the soil to the plants and its growth and activity depends on the availability of soil n. our objective was to investigate how the availability of n in the soil affects growth and the accumulation of n in inoculated strawberry plants. root colonisation, dry ma ... | 2012 | 22331548 |
| purification and identification of an ige suppressor from strawberry in an in vitro immunization system. | we purified and identified an ige suppressor from the strawberry 'toyonoka', based on the decrease of ige production in in vitro immunization (ivi). gel filtration experiment indicated that fractions in a 15-48 kda range and <10 kda have an ige suppressive activity. furthermore, the fraction in 15-48 kda was subjected to chromatofocusing and found to have activities at isoelectric points, pi 6.0, 7.0, and 8.0-9.2. we focused on the active fractions of pi 8.0-9.2 and the purified a large amount o ... | 2012 | 22328134 |
| photoprotective potential of strawberry (fragaria × ananassa) extract against uv-a irradiation damage on human fibroblasts. | exposure to uv-a radiation is known to induce discrete lesions in dna and the generation of free radicals that lead to a wide array of skin diseases. strawberry (fragaria × ananassa) contains several polyphenols with strong antioxidant and anti-inflammatory activities. because the major representative components of strawberry are anthocyanins, these may significantly contribute to its properties. to test this hypothesis, methanolic extracts from the sveva cultivar were analyzed for anthocyanin c ... | 2012 | 22304566 |

| a sepallata gene is involved in the development and ripening of strawberry (fragaria x ananassa duch.) fruit, a non-climacteric tissue. | climacteric and non-climacteric fruits have traditionally been viewed as representing two distinct programmes of ripening associated with differential respiration and ethylene hormone effects. in climacteric fruits, such as tomato and banana, the ripening process is marked by increased respiration and is induced and co-ordinated by ethylene, while in non-climacteric fruits, such as strawberry and grape, it is controlled by an ethylene-independent process with little change in respiration rate. t ... | 2011 | 21115665 |
| solar uvb response of bioactives in strawberry (fragaria × ananassa duch. l.): a comparison of protected and open-field cultivation. | strawberries (fragaria × ananassa duch. cvs. everest, elsanta) were grown in a tunnel covered with two films, which were distinguished in their ultraviolet transparency, as well as under open-field conditions. one applied film was not transparent for uvb radiation, and the second film transmitted 70% of uvb radiation. during the present study, the nutritional value and quality parameters of the fruits were evaluated. strawberries were uv-unresponsive in view of the content of ascorbic acid and s ... | 2010 | 21086998 |
| variation in preference and performance of frankliniella occidentalis (thysanoptera: thripidae) on three strawberry cultivars. | western flower thrips, frankliniella occidentalis (pergande) (thysanoptera: thripidae), is a major pest of strawberry, causing substantial yield loss through direct feeding on the flowers and fruit. insecticides are the main method used for its control; however, f. occidentalis has developed resistance to insecticides from all major chemical classes. chemical control is not a long-term strategy and integrated pest management is required. this study determined whether f. occidentalis damage could ... | 2010 | 21061975 |
| metabolic profiling of strawberry (fragaria x ananassa duch.) during fruit development and maturation. | strawberry (fragaria × ananassa duch), a fruit of economic and nutritional importance, is also a model species for fleshy fruits and genomics in rosaceae. strawberry fruit quality at different harvest stages is a function of the fruit's metabolite content, which results from physiological changes during fruit growth and ripening. in order to investigate strawberry fruit development, untargeted (gc-ms) and targeted (hplc) metabolic profiling analyses were conducted. principal component analysis ( ... | 2011 | 21041374 |
| incorporation of intraguild predation into a pest management decision-making tool: the case of thrips and two pollen-feeding predators in strawberry. | action thresholds are traditionally based on the density of pests and the economic damage they cause to crops. pest damage assessments are usually made in a "sterile" environment, devoid of extenuating factors such as predators, parasitoids, and alternative food sources. recently, the effects of a predator or parasitoid species have been considered. however, interactions between natural enemy species (intraguild predation and interference), which are common in agricultural fields, have not been ... | 2010 | 20857715 |

| assessment of the influence of different sample processing and cold storage duration on plant free proline content analyses. | a method which is widely accepted for the analysis of free proline content in plant tissues is based on the use of 3% sulfosalicylic acid as an extractant, followed by spectrophotometric quantification of a proline-ninhydrin complex in toluene. however, sample preparation and storage may influence the proline actually measured. this may give misleading or difficult to compare data. | 2013 | 20603866 |
| root colonisation by the arbuscular mycorrhizal fungus glomus intraradices alters the quality of strawberry fruits (fragaria x ananassa duch.) at different nitrogen levels. | arbuscular mycorrhizal fungi (amf) increase the uptake of minerals from the soil, thus improving the growth of the host plant. nitrogen (n) is a main mineral element for plant growth, as it is an essential component of numerous plant compounds affecting fruit quality. the availability of n to plants also affects the amf-plant interaction, which suggests that the quality of fruits could be affected by both factors. the objective of this study was to evaluate the influence of three n treatments (3 ... | 2010 | 20572056 |
