The effect of plant biostimulation on fruits of traditional tomato germplasm is largely unknown. We examined how a tropical plant-derived biostimulant impacts the nutritional, functional, and compositional characteristics of tomato fruits from four landraces, collected in the San Marzano (SM) tomato Protected Designation of Origin (PDO) region, by profiling primary and secondary metabolites. Biostimulation was not able to completely reshuffle the morpho-physiological and nutritional profile of the four landraces. Their distinct phytochemical profile indicated a genotype-specific tuning of the analyzed traits, which also included an improved yield and fruit quality. Biostimulation of SM1 and SM3 increased photosynthetic accumulation of carbohydrate reserves, improved mineral nutrient use efficiency and consequently, yield (+21% and 34%, respectively). Moreover, biostimulation augmented the nutraceutical properties of the SM2 landrace. Interestingly, the plant-derived product increased in all genotypes lycopene, but not polyphenol accumulation in fruits. Our results show the potential of biostimulatory applications towards optimizing the fruit quality of the acclaimed SM landraces, which is suitable to satisfy both the rising consumer demand for premium traditional tomatoes and the technological needs of the food industry.

This study was carried out during three successive seasons 2011, 2012 and 2013 at a private orchard located in Al- Hello in Ajman Emirate (UAE). The experiment was designed to study the effect of organic manure and NPKS as soil application on yield, fruit quality, and fruit mineral nutrient content of Khenazi date palm cultivar grown in sandy soil. Fertilization treatments consisted of N1, 600g or N2, 1000g (urea 46%N), P 800g (triple superphosphate, 48% P2O5), K 1200g (potassium sulphate, 50% K2SO4) and S 700g sulphur (90% granular S), in addition to organic manure. Al experimental trees received 100g mixture of micronutrients, with the exception of the control. The results showed that combination treatments and organic manure significantly affected fruit weight, flesh weight, fruit volume, moisture content and fruit TSS. Application of different fertilization treatments significantly affected yield components of fruit, number of fruits/strand, fruit number/bunch, fruit set percent and total fruit yield / palm. The study revealed that combination of fertilizers improved fruit nutrient content of N, P, K, Ca, Mg, Fe, Zn, Mn and Cu. Moisture and TSS% content, number of fruits/strand, number of fruits/bunch, fruit nutrients content of Fe, Mn and Zn were significantly different due to the application of N1+K+S.

Preharvest fruit drop (PFD) of apple (Malus domestica Borkh.) can cause significant losses resulting in up to 50% reduction in yield in some years. In a 2-yr study, ‘Honeycrisp’ trees were treated with six foliar treatments including 20 mg·L−1 1-naphthaleneacetic acid (NAA) 2 wk before anticipated harvest (WBAH), 125 mg·L−1 aminoethoxyvinylglycine hydrochloride (AVG) 4 WBAH, AVG plus NAA 2 WBAH, and repeat sprays of 200 mg·L−1 B, and 2000 mg·L−1 Mg applied 48–93 d after full bloom to evaluate their effect on PFD and fruit quality. Fruit drop associated with broken pedicels and physiological causes was monitored. During a year with ∼43% PFD on untreated control trees, AVG retained up to ∼35% and NAA retained up to ∼27% of the total fruit number, relative to the control trees. The combination of AVG plus NAA had similar PFD compared with AVG alone, while B and Mg were similar to the control. The proportion of PFD associated with broken pedicels was ∼5%. Aminoethoxyvinylglycine delayed starch degradation, ethylene evolution, and blush skin colour development of fruit. This study supports the use of AVG 4 WBAH and NAA 2 WBAH to manage ‘Honeycrisp’ PFD, which may offer economic advantages for growing quality apples. Foliar sprays of Mg or B failed to reduce PFD.

Postharvest Storage

Mineral nutrition, taken up from the soil or foliar sprayed, plays fundamental roles in plant growth and development. Among of at least 14 mineral elements, the macronutrients nitrogen (N), potassium (K), phosphorus (P), and calcium (Ca) and the micronutrient iron (Fe) are essential to Rosaceae fruit yield and quality. Deficiencies in minerals strongly affect metabolism with subsequent impacts on the growth and development of fruit trees. This ultimately affects the yield, nutritional value, and quality of fruit. Especially, the main reason of the postharvest storage loss caused by physiological disorders is the improper proportion of mineral nutrient elements. In recent years, many important mineral transport proteins and their regulatory components are increasingly revealed, which make drastic progress in understanding the molecular mechanisms for mineral nutrition (N, P, K, Ca, and Fe) in various aspects including plant growth, fruit development, quality, nutrition, and postharvest storage. Importantly, many studies have found that mineral nutrition, such as N, P, and Fe, not only affects fruit quality directly but also influences the absorption and the content of other nutrient elements. In this review, we provide insights of the mineral nutrients into their function, transport, signal transduction associated with Rosaceae fruit quality, and postharvest storage at physiological and molecular levels. These studies will contribute to provide theoretical basis to improve fertilizer efficient utilization and fruit industry sustainable development.

Abstract 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.

A spontaneous tomato (Lycopersicon esculentum Mill.) triploid was studied with a view to its commercialization. Fruits induced by auxin contained 50% more DNA and 30% more protein than their diploid counterpart. The fruits were 50% larger than those of the diploid counterpart and were juicy but seedless. All fruit quality characteristics checked (polygalacturonase activity, reducing sugars content, electrical conductivity, pH, titratable acidity, pigment content, and shelf life) were comparable to the diploid except for ethylene evolution rate, which was lower than that of the diploid counterpart, and flavor, which was superior. The line seems suitable for agricultural cultivation.

This experiment was conducted to evaluate the effect of fruit quality, ethylene evolution, and storage in apple `Tsugaru' as influenced by aminoethoxyvinylglycine (AVG) and several surfactants. When treated with AVG + Silwet L-77, there was little significant difference in soluble solids and acidity as compared with control, but dichlorprop treatment was significantly increased in soluble solids and decreased in acidity. Color development was decreased when treated with AVG + Silwet L-77. AVG + Silwet L-77 treatment decreased ethylene evolution, and increased storage. It can be concluded that fruit can be left on trees longer and still maintain storability, and more fruit is able to go to fresh market from long-term storage, which increases the marketability of apple.
