“…In our opinion, being blueberry texture determined by several physical constrains, such as cell turgor, peel elasticity, and cell wall structure, the destructive evaluation of blueberry fruit by texturometer is preferable than the non-destructive assessments based on fruit compression (i.e. Firmtech II; Li et al., 2011 ; Giongo et al., 2019 ), laser induced method ( Li et al., 2011 ), hyperspectral imaging ( Hu et al., 2015 ), or Vis-NIR spectroscopy ( Hu et al., 2018 ). Application limits of these non-destructive techniques are still the need of a constant updated calibration of the predictive multivariate algorithm, and the low spatial and spectral resolution ( Li et al., 2019 ).…”

Improved fruit quality and prolonged storage capability are key breeding traits for blueberry (Vaccinium spp.) fruit. Until now, breeding selection was mostly oriented on the amelioration of agronomic traits, such as flowering time, chilling requirement, or plant structure. Up until now, however, the storage effect on fruit quality has not been extensively studied, mostly because objective and handy phenotyping tools to evaluate quality traits were not available. In this study we are proposing a novel phenotyping protocol to support breeding selection and quality control within the entire blueberry production chain. Volatile organic compounds (VOCs) and texture traits, were measured by Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) and a texture analyzer respectively, taking into consideration the influence of prolonged storage. The exploitation of the genetic variability existing within the investigated blueberry germplasm collection (including both southern and northern highbush, hybrids, and rabbiteyes) allowed the identification of the best performing cultivars, based on texture and VOCs variability, to be used as superior parental lines for future breeding programs. The comprehensive characterization of blueberry aroma allowed the identification of a wide array of spectrometric features, mostly related to aldehydes, alcohols, terpenoids, and esters, that can be used as putative biomarkers to rapidly evaluate the blueberry aroma variations related to genetic differences and storability. In addition, this study revealed a lack of straightforward relationship between harvest and postharvest quality features, that might be genotype-dependent.

“…Strawberry fruit rmness was measured by a texture analyser (Zwick Roell, Italy) using the penetration test methodology that was previously developed for raspberry 66 . This penetration test outlined a mechanical force displacement using a 5 kg loading cell and a cylindrical at head probe with a diameter of 4 mm entering into the berry esh that was placed on the plate with the receptacle upright to the compression probe.…”

BackgroundCultivated strawberry (Fragaria × ananassa Duch., fam. Rosaceae) is an important fruit crop, greatly appreciated for its aroma and nutraceutical properties. Niche-specific characterisation of plant microbiome, from rhizosphere to aboveground plant organs, is crucial to understand the influence of structure and function of the microbial communities on plant phenotype, performances and disease resistance. Strawberry cultivation is challenged by a large variety of pathogens, which cause substantial economic losses and require the frequent application of pesticides. Biological control is a promising and safer alternative to the use of xenobiotic pesticides. Biological control agents isolated from the microbiome of the host plant may have a superior efficacy in comparison to non-indigenous microbial inoculants. Therefore, the characterization of the native microbiome along different plant compartments is a key step for the successful microbial manipulation in farmlands. Results Here, we provide the first comprehensive description of the soil, rhizosphere, root and aerial parts microbiome of three commercially important strawberry cultivars (‘Darselect’, ‘Elsanta’ and ‘Monterey’) under cultural conditions. The fungal and bacterial microbiomes were functionally characterised to investigate their influence on plant disease tolerance, plant mineral nutrient content and fruit quality. The core microbiome included 24 bacteria and 15 fungal operative taxon units which were present in all compartments and plant genotypes. However, both plant organ and genotype had a significant role in assembling the microbial communities. The microbial community assemblage across different soil and plant compartments significantly correlated with disease resistance, mineral nutrient content in the plant and with fruit quality parameters. Interestingly, only the disease tolerant genotype ‘Monterey’ was able to recruit Pseudomonas fluorescens in all plant organs and to establish symbiosis with the arbuscular mycorrhiza Rhizophagus irregularis. These two species include several strains acting as pathogen biocontrol agents, plant growth promoters and plant defence inducers. Conclusions Altogether, our study provides the first comprehensive view of strawberry microbiome in relation to plant genotype, health and nutritional status and fruit quality parameters, shedding light on potential practical applications to increase the sustainability of crop production.

“…Variety textural profile is important in grape blanching processes 32 , since its changes are closely related to cell-wall structure. Texture can affect processing events, like drying and fermentation 50,51 , but it also strongly influences sensory quality and consumers' satisfaction when the fresh product is consumed 52,53 .…”

Grapevine is a well-known host plant of the invasive pest Drosophila suzukii, but its susceptibility to pest oviposition and development greatly depends on the cultivar. to address environmental sustainability during viticultural zoning planning, new vineyard plantation and integrated pest Management programmes, it is essential to take pest pressure and cultivar susceptibility into account. to determine the different grapevine cultivars susceptibility to D. suzukii, we tested twelve widely spread cultivars during the ripening period. We also tested three cultivars during the drying period for raisin wine production. the infestation and emergence rates were consequently related to chemical and texture features of the berries to explain the role of skin and pulp characteristics in determining the nature of the susceptibility. our results showed that susceptibility to D. suzukii infestation varies across cultivars. On ripening grapes, infestation is primarily influenced by skin and pulp firmness, elasticity and consistency. Suitability for egg development resulted mainly related to skin and pulp deformation. in a drying loft, infestation may also occur in relation to skin and pulp consistency. Lastly, we discuss the practical implication of the underestimated role of berry texture in D. suzukii oviposition and emergence success, in both ripening and drying grapes.
