“…'Alba' strawberries the highest decay reductions were obtained after benzothiadiazole treatments, while with 'Romina', laminarin and chitosan provided the best performances. Differences in treatment responses among varieties were observed by Lopes et al (2014) as well. In their study, chitosan application to strawberry plants in the field in combination with postharvest dipping of fruits was an effective strategy for controlling gray mold in strawberry in 'Oso Grande' but was not effective in the variety 'Camarosa' (Lopes et al, 2014).…”

In the same way, in our study the effectiveness of preharvest treatments with resistance inducers in controlling postharvest decay largely varied among the two strawberry varieties.…”

“…The preharvest chitosan treatments delayed strawberry maturation, increased the flesh firmness, and decreased the fruit weight loss (Mazaro et al, 2008). Chitosan sprays were not phytotoxic to the plants or the fruit at the concentration of 1% or lower (Bhaskara Reddy et al, 2000;Lopes et al, 2014;Mazaro et al, 2008;Romanazzi et al, 2000). With respect to previous preharvest trials, which used practical grade chitosan, in the present study the commercial formulation for chitosan was used, as it can be easily dissolved in water.…”

“…Soil application of liquid potassium silicate to cucumber plants notably reduced the incidence of gray mould caused by B. cinerea (O'Neil, 1991). In contrast, post-harvest Si application was found to be ineffective for controlling gray mould (B. cinerea) in strawberry (Lopes et al, 2014).…”

Silicon (Si) has proven to enhance disease resistance in a wide range of tropical fruits and vegetables. It has been used in controlling various diseases: mildews, rots, moulds, wilt, blight, anthracnose and leaf spots. However, the highest number of records was available on reducing diseases of powdery mildews on fruits and vegetables belonging to the family Cucurbitaceae. Siliconmediated defense responses in plant pathosystems are mainly attributed to the physical resistance, which involves reduced penetrability and/or increased hardness and abrasiveness of plant tissues because of silica deposition. The main mechanism is the chemical resistance, which involves chemical defenses to pathogen attack through the enhanced production of defensive enzymes and the production of antifungal compounds such as phenolic metabolism products, phytoalexins and pathogenesis related proteins. Silicon has been applied as soluble silicates to the substrate or to soilless media at pre-harvest level on reducing disease susceptibility. Post-harvest dips of fresh produce in silicate solutions and use of Si combined with a biocontrol agent are other aspects of silicon application in controlling diseases in fruits and vegetables.

“…Chitosan, the deacetylation product of chitin, has been recently used as a promising alternative postharvest diseases management. Diverse studies have shown the efficiency of chitosan in controlling postharvest rot of horticultural commodities caused by plant pathogenic fungi, such as Aspergillus flavus (Dias et al, 2018), Botrytis cinerea (Lopes et al, 2014), Ceratocystis fimbriata (Xing et al, 2018), Pilidiella granati (Munhuweyi et al, 2017) and P. expansum (Wang et al, 2014). On addition to its potential to elicit plant defense by increasing the production of defense-related secondary metabolites and promoting the expression of defense-related enzymes (Hadwiger, 2013), chitosan also exhibits direct antimicrobial activities against plant pathogens (Xing et al, 2015).…”

The antimicrobial effect of chitosan on Penicillium expansum, a major postharvest pathogen of pome fruit, and the possible mechanisms involved in its effect were examined in this study. Chitosan strongly inhibited spore germination and hyphal growth of P. expansum. Light microscopy and transmission electron microscopy observations revealed that chitosan also caused morphological changes in hyphae and conidia, such as abnormal branching and vacuolation. Proteomic changes in P. expansum after chitosan treatment were analyzed by two-dimensional electrophoresis (2-DE) and mass spectrometry (MS) analysis, and 26 proteins were ambiguously identified and categorized based on their putative biological function. Proteins related to DNA or protein biosynthesis, carbohydrate metabolism and energy production were decreased in relative protein abundance, while proteins involved in antibiotics resistance and defense response increased in relative protein abundance. Changes in abundance of these identified proteins were in accordance to the observed physiological and morphological changes of the fungi cells. Altogether, these experimental results provide a detailed illustration of the responses to chitosan in P. expansum, and widen our knowledge on the potential antifungal mechanisms of chitosan.
