TL;DR: This review gives an up to date overview of the recent advances in the production of quality AMF inocula and in the biostimulant properties of AMF on plant health, nutrition and quality of horticultural crops (fruit trees, vegetables, flower crops and ornamentals).

TL;DR: An overview of the biostimulant properties of PHs on productivity and product quality of horticultural crops, in particular fruit trees, vegetables, flower crops and ornamentals is given.

TL;DR: Recent proteomic and genetic data suggest that Trichoderma activates the mitogen activated protein kinase 6, transcription factors and DNA processing proteins, which represent promising targets toward formulation of more efficient products.

TL;DR: This review summarizes recent progress in the understanding of the PGPR-plant interaction and highlights future lines of research that should increase the knowledge on plant-bacterial communication and that can help to improve the effective use of PGPR in horticulture.

TL;DR: Chitosan has been used both as a biostimulant to stimulate plant growth, and abiotic stress tolerance, and as to induce pathogen resistance; however, these responses are complex and they depend on different chitOSan-based structures and concentrations as well as the plant species and developmental stage.

TL;DR: A review of analytical methods for determination of sugars and sweetness of fresh and processed fruit and vegetables, including the use of destructive and non-destructive instrumental techniques to evaluate sugar composition and characterize taste profile or sweetness, can be found in this paper.

TL;DR: The state-of-the-art of capabilities of AMF to increase the productivity of vegetable crops by growth promotion, amelioration of stress, biocontrol of pathogens and to improvement of the chemical quality are examined.

TL;DR: It is proved that the application of plant-derived protein hydrolysate increases plant performance when plants are grown under salinity conditions and the most favorable metabolic profile was obtained when biostimulant was applied to both roots and leaves.

TL;DR: In this article, a review of the biostimulating effects of silicon on plants exposed to abiotic stress are considered, and the key mechanisms involved in Si-mediated alleviation of abiotic stresses in higher plants include: (1) silica deposition inside the plant tissues which provides mechanical strength and erectness to leaves and modulates nutrient and water mobility inside the plants, stimulation of antioxidant systems in plants, complexation or co-precipitation of toxic metals with Si both in plant tissues and in soil.

TL;DR: In this article, the effect of hydrogen sulfide (H 2 S) fumigation on banana fruit during chilling storage followed by a ripening period was evaluated and it was found that H 2 S fumigated banana fruit maintained higher values of lightness, peel firmness and reduced accumulation of malondialdehyde.

TL;DR: Under mild drought stress A. nodosum SWE enhanced spinach growth by improving leaf water relations, maintaining cell turgor pressure and reducing stomatal limitation, which in turn led to large leaf area and high photosynthetic rate.

TL;DR: In this article, the effect of gum arabic (GA) 10% and calcium chloride (CA) 3% on the physiological and biochemical properties of mango (Mangifera indica L. CV) fruits stored at 6 ± 1 °C and 90 ± 3% relative humidity for 28 days and then transferred to 25 ± 2 °C for 5 days shelf life were investigated.

TL;DR: Biological controls, especially plant growth-promoting rhizobacteria that are used for biofertilizers, biocontrol agents, and bioremediators are focused on.

TL;DR: Investigating the production of phytochemicals that determine fruit quality, and evaluating growth characteristics of mature strawberry plants during cultivation under three different wavelengths of LED light found that a remarkably higher production of fruits was achieved in the PG when ambient light was supplemented with either blue LED light or combined blue and red LED light.

TL;DR: In this article, a new biotechnological tool with the potential to accelerate the conversion from conventional to organic industrial tomato production by combining the benefits of the plant growth-promoting bacteria (PGPB) Herbaspirillum seropedicae and humates was evaluated.

TL;DR: In this article, the physiological and phytochemical plant responses to LED lights in indoor cultivation of leafy and fruit vegetable crops (namely, sweet basil, Ocimum basilicum L.; and strawberry, Fragaria × Ananassa), with the final aim of improving both productivity and nutritional quality.

TL;DR: In this article, the effects of different light emitting diode (LED) light spectra on the growth and quality of Valerianella locusta plants in greenhouse cultivation were evaluated.

TL;DR: The current advances in research on the impact of Phi as a novel biostimulant for horticultural production are outlined and some strategies being used to improve the yield and quality of important crop species are discussed.

TL;DR: The combined seed soaking in SA + foliar spray with MLE treatment was found to be highly effective at improving the growth and yields of bean plants by alleviating the inhibitory effects of soil salinity stress.

TL;DR: In this paper, the changes of fruit firmness, cell wall degrading enzymes and cell wall composition of ‘Brilliant’ blueberry ( Vaccinium ashei cv. Brilliant) were investigated.

TL;DR: This work has characterised flower development in sweet cherry, framing it in the BBCH scale, and provides a unified standardised approach for phenological comparative studies.

TL;DR: The results suggest that seed inoculation with Azospirillum not only could improve freshly product quality but also extend storage life in lettuce grown under salt stress.

TL;DR: In this paper, the results of studies conducted so far worldwide on the impact of PGPR carrying numerous multi-functional plant growth promoting activities on horticultural crops especially vegetables grown distinctively in different production systems is discussed and considered.

TL;DR: The levels of phenols, the activities of both peroxidase and polyphenolxydases have significantly increased in the roots of mycorrhization and non-mycorrhized palms exposed to severe water stress, and these levels are higher in myCorrhized palm than in the control palms.

TL;DR: In this paper, the authors used a recirculating ebb-and-flow system to evaluate the growth, yield, quality, and potential gross returns of four crops (Ocimum basilicum L, kale (Brassica oleracea L), chipotle pepper (Capsicum annuum L.), and cherry tomato (Solanum lycopersicum L.) grown in a hydroponic and aquaponic system.

TL;DR: Si protected the structure of the chloroplast from severe oxidative damage, such as the distortion of the grana lamellae and stroma lameLLae, and might be involved in metabolic or physiological activities in Si non‑accumulating plants under drought stress.
