BACKGROUND: The production of fruit and vegetables rich in health-promoting components in an eco-friendly context represents the winning answer to the world population demand for food. In this study, the effects of different treatments on the yield and fruit chemical characteristics of tomato (Solanum lycopersicum L.) are reported. The treatments included three inducers of plant defence responses (chitosan, Trichoderma harzianum T-22 and Bacillus subtilis QST713) applied alone or before Cucumber mosaic virus infection. Fruit production and antioxidant compounds were investigated by ultrahigh-performance liquid chromatography (UHPLC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: Compared to control fruit harvested from untreated and healthy plants, treatment with QST713 increased the fruit number. Furthermore, plant treatments with T22, QST713 and chitosan alone enhanced fruit carotenoids (lutein and -carotene), ascorbic acid and phenolic acids (caffeoyl glucoside and p-coumaroyl glucoside). In parallel, compared to fruit harvested from only CMV-infected plants, treatments with T22, QST713 and chitosan before CMV enhanced fruit ascorbic acid and flavonoids (quercetin 3-O-xylosyl-rutinoside and rutin). CONCLUSION: Antioxidant compounds of tomato fruit can increase with the application of the plant defence inducers, thus protecting both the consumer and plant health. Statistical data analysisData normal distribution was tested using the Shapiro-Wilk test (P ≤ 0.05) and homoscedasticity using Bartlett's test (P ≤ 0.05). Data were analysed by one-way analysis of variance (ANOVA), parametric and non-parametric, performing Tukey's HSD and Kruskal-Wallis test, respectively. Statistical data analyses were carried out using RStudio software, version 1.0.136 (Integrated Development for R; Boston, MA, USA).J Sci Food Agric 2019; 99: 5541-5549

“…Seed priming with chitosan alters the permeability of seeds' plasma membrane, enhances peroxidase, catalase, tyrosine ammonia lyase activity, and increases antioxidant activity [1,24]. Germination and growth rate of maize, nuts, fruits, and many other vegetable seeds increased by the application of chitosan [7,18,[24][25][26]. Earlier studies also reported that foliar application of chitosan enhanced growth and development as well as yield of strawberry [7,18].…”

Chitosan biostimulant controls infection of cucumber by Phytophthora capsici through suppression of asexual reproduction of the pathogen

The biopolymer chitosan is a derivative of chitin, which can promote plant growth and protect plants from phytopathogens. This study aimed to evaluate the efficacy of chitosan as a biostimulant and a biorational agent to protect cucumber plants from damping-off disease caused by Phytophthora capsici. Cucumber seeds were treated with a range of chitosan concentrations, viz. 0, 125, 250, and 500 ppm, to evaluate effect on seed germination and fresh root and shoot weight of the seedlings. Chitosan significantly (p ≤ 0.05) enhanced seed germination and root and shoot growth of cucumber in a dose-dependent manner up to 500 ppm. Application of in vitro chitosan suspension onto P. capsici mycelial plug suppressed growth of mycelia, formation of sporangia, and release of P. capsici zoospores at 125–500 ppm concentrations. Cucumber seedlings from chitosan-treated seeds showed enhanced resistance to damping-off disease caused by P. capsici compared to untreated control. Cucumber seedlings from 500 ppm chitosan seed treatment showed 100% disease resistance against damping off caused by P. capsici. These results suggest that chitosan could be used as a natural and environmentally safe alternative to a synthetic growth promoter and pesticide for sustainable production of cucumber.

“…Foliar application of 100-125 mg/L chitosan every 15 d increased okra fruit production, as well as plant height, leaf number, relative growth rate, photosynthesis rate and NR activity, but had no effect on the chlorophyll content (Mondal et al, 2012). The foliar spraying of chitosan on tomato plants increased the fruit weight and yield (Sathiyabama et al, 2014).…”

“…Chitosan induces PRPs, especially chitinase and glucanase, in several crops, including grape (V. vinifera L.; Trotel-Aziz et al, 2006), pear (Pyrus pyrifolia (Burm. f.) Nakai; Meng et al, 2010), papaya (C. papaya L.; Ali et al, 2012;Hewajulige et al, 2009), peach (Prunus persica (L.) Batsch; Ma et al, 2013), tomato (Sathiyabama et al, 2014), dragon fruit (Hylocereus undatus (Haworth) Britton & Rose; Ali et al, 2014), and coconut (Cocos nucifera L.; Lizama-Uc et al, 2007). The increase in glucanase or chitinase levels was associated with the increased disease resistance, suggesting that the chitosan-induced disease resistance was potentially based on the induction of these enzymes.…”
