Although Lilium brownii (L. brownii) bulbs are popular fresh vegetables, a series of quality problems still remain after harvest. In this study, L. were placed in the dark at 25, 4, and ?20 °C under light 25 from 0 to 30 days; chemical compositions analyzed by ultraviolet spectrophotometry (UV) high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). D...

‘Huangguan’ pear (Pyrus bretschneideri Rehd. cv. Huangguan) is a widely planted cultivar in China. However, it susceptible to core browning after harvest. In this study, aminoethoxyvinylglycine (AVG) was applied at 200 mg L?1 one and two weeks prior harvest, its effects on fruit quality, ripening were investigated during storage ambient temperature (25 ± 1 °C). The results showed that there hig...

The susceptibility of soybean genotype to Agrobacterium infection is a key factor for the high level of genetic transformation efficiency. The objective of this study is to evaluate the plant factors related to transformation in cotyledonary nodes during the Agrobacterium infection process. This study selected three genotypes (Williams 82, Shennong 9 and Bert) with high transformation efficienc...

The Pseudomonas fluorescens isolate Pfl was found to inhibit the growth of pathogen Alternaria palandui, in vitro. In the present study, foliar application of a talc-based formulation of Pfl significantly reduced the incidence of leaf blight of onion, caused by A. palandui. Induction of defense-related proteins viz., chitinase, beta-1,3 glucanase, peroxidase (PO) and polyphenol oxidase (PPO) by...

Oligandrin is an elicitin-like protein with a molecular mass of 10 kDa secreted by Pythium oligandrum. Here, the effect of oligandrin on defense response against Botrytis cinerea in tomato leaves is reported. Tomato seedlings were pretreated with 5 ml oligandrin (10 g/ml) by root submerging and then inoculated with B. cinerea. Disease severity was subsequently evaluated and compared with the co...

Peel browning disorder has an enormous impact on the exterior quality of 'Huangguan' pear whereas the underlying mechanism is still unclear. Although different methods have been applied for inhibiting the peel browning of 'Huangguan' pear, there are numerous issues associated with these approaches, such as time cost, efficacy, safety and stability. In this study, to develop a rapid, efficient a...

The aim of this study was to evaluate the effects silver nitrate (AgNO3) and nano-silver (Ag-NPs) on physiological biochemical characteristics, quality grape bunches during a cold storage period. For investigations, two varieties grapes were used, Shine Muscat Kyoho, with different concentrations AgNO3 Ag-NPs post-harvest dipping. data indicated that enhanced fruits’ longevity quality. Dependin...

Phytophthora cinnamomi causes one of the most important diseases in avocado crop and its chemical management represents 25% production cost per year. Induction plant defense responses by elicitors is a promising strategy that compatible with sustainable agriculture. This study aimed to evaluate effect curdlan application on induction plants against P. cinnamomi. The trials were conducted under ...

Clarified and standardized apple juice was ultraviolet-irradiated to inactivate polyphenol oxidase enzyme and microbiota, and its effect on bioactive compounds and stability during storage was also evaluated. Apple juice was irradiated with 345.6 J/cm² and treatment effect was evaluated in terms of color, antioxidant capacity, polyphenol content, pH, titratable acidity and total soluble solids....

Plant polyphenol oxidases (PPOs) are ubiquitous plastid-localized enzymes. A precise analysis of PPO function in plants has been complicated by the presence of several family members with immunological cross reactivity. Previously we reported the isolation of genomic clones coding for the seven members of the tomato (Solanum lycopersicum) PPO family (A, A', B, C, D, E, and F). Here we report th...
