“…The increase in PAL activity correlated with an induction of resistance on fruit peel. This enzyme has been associated to the induced systemic resistance and elicits plant defense responses to biotic and abiotic stress (Terao et al, ). In agreement of our finding, Chen et al () showed that PAL activity in the fruits treated with carboxymethyl cellulose (1.5%, CMC) containing extract of Impatiens balsamina L. was significantly higher than the CMC coating‐treated and the control fruits.…”

There is a growing interest in using natural antifungal compounds for the preservation of foods. The first experiment of this study was investigated an effect of pomegranate peel extract (PPE) and the essential oil (PPEO) in different concentrations mixed with potato dextrose agar (PDA) on spore germination of Penicillum italicum and Penicillum digitatum. in vivo experiments were focused on the treatments offering potential antifungal and antioxidant benefits. Preventive treatments were performed by dipping wounded fruit into the specific concentrations of extract and thereafter, each wound site was infected by inoculating 20 μL of the inoculum of P. italicum or P. digitatum. For curative treatments, fruit were wounded as above, and then inoculated with P. italicum or P. digitatum. Even though data showed no significant differences between PPEO treatments, PPE at 100 and 125 ppm elicited significantly lower spore germination under in vitro conditions compared to the other treatments. The results showed that 75% or/and 100% PPE reduced infected wound percentage and lesion diameter and increased total phenolic, flavonoid compounds content, and phenylalanine ammonia‐lyase activity in “Satsuma” mandarin rind. The tested PPE can be effectively utilized for controlling and curing infections caused by P. italicum and P. digitatum. Practical applications The results obtained in this research could be advantageously used by industry as a request of consumer demand for pesticide‐free food. The results indicate that it is possible to substitute the synthetic compounds with preservatives safer for man and environment.

“…The doses from 0.5 to 3.5 kJ/m 2 of UV‐C light were tested using the irradiator described in Terao et al. (). The system consisted of an acrylic box with reflecting surface at the top, with germicidal lamp of 36‐W, with an average power of 370 μW/cm 2 , adjusting the exposure time, according to Eq.…”

Botryosphaeria dothidea is the major pathogen of mango in Brazil, causing stem‐end rot, which causes significant losses during transportation and storage. The current strategy to control this particular disease using synthetic fungicides has been ineffective, leaving residues in the fruit. The objective of the research was to study the effect of physical treatments, with hot water rinse brushing (HWRB) and ultraviolet C irradiation (UV‐C), individually and in combination, to control stem‐end rot of mango. Physicochemical parameters, respiration and resistance induction of the fruit were also analysed. The in vitro trials demonstrated that B. dothidea is a thermoresistant fungus. The individual treatments with HWRB at 65°C for 15 s and 2.5 kJ/m2 of UV‐C presented the best results, showing less symptoms of the disease during 18 days of storage. The combination of HWRB with UV‐C did not improve the control of the disease when compared to the treatments applied individually. The physicochemical parameters and the consumer acceptance evaluation showed that both physical treatments preserved the appearance of the fruit and delayed the ripening–senescence process. The induction of defence‐related enzymes revealed that induced resistance was an important mechanism involved in the control of stem‐end rot of mango.

“…Besides good sensorial characteristics, citrus contain high levels of antioxidant compounds, including vitamin C, avanones, and anthocyanins [2,3]. However, citrus fruits are exposed to many postharvest diseases during transportation and storage, among which green mold, caused by Penicillium digitatum, is one of the most devastating diseases, causing signi cant economic and resource losses in the world [4][5][6]. In addition, P. digitatum can cause an allergic response by producing countless air-borne spores [3,7].…”

The effectiveness of the bacteria antagonist Pseudomonas fluorescens to control green mold caused by Penicillium digitatum on oranges (Citrus sinensis Osbeck, cv. Jincheng) and the possible modes of action were evaluated. Whether in vitro or in vivo, treatments with cell-free autoclaved cultures or culture filtrate had limited capacity to suppress P. digitatum, while P. digitatum was significantly inhibited by bacterial fluid (P. fluorescens in the nutrient broth liquid medium) and bacterial suspension (P. fluorescens in sterile distilled water) with living cells. There was a positive relationship between the concentration of P. fluorescens in bacterial suspension and its biological efficacy. In addition, P. fluorescens was effective when applied preventatively but not when applied curatively. In the inoculated wounds, the population of P. fluorescens was an approximately 28- and 34-fold increase after being incubated at 20°C for 8 d and at 4°C for 16 d, respectively, and P. digitatum could effectively stimulate the growth and reproduction of P. fluorescens. Moreover, P. fluorescens was able to inhibit spore germination and germ tube elongation of P. digitatum as well as induce resistance on citrus peel by increasing the chitinase (CHI) activity and advancing the activities peaks of β-1,3-glucanase (GLU), peroxidase (POD), and phenylalanine ammonia lyase (PAL). All of these results support the potential application of P. fluorescens against green mold on postharvest citrus.
