“…In agreement with our results, PAA increased watercress plant height, leaf length, and improved the yield (Carrasco et al, 2011). In another study on hydroponically-grown, 1-weekold tomato seedlings, treatment with PAA showed a concentration-dependent reduction in the growth of all vegetative organs (Vines et al, 2003). The authors also reported that PAA was less toxic to older plants and to those grown on solid substrates (Vines et al, 2003).…”

Attempts are being made to minimize the use of synthetic chemicals such as fungicides. There is an interest toward the use of environmentally-friendly products to minimize impact of toxic residuals on human, animals, and environment. Two-season field experiments were conducted in 2018 and 2019to investigate the effectiveness of foliar sprayings of three products [potassium silicate (PS), perbicarbonate (PB), and peroxyacetic acid (PAA)] as singular or sequential treatments (totaling 10 treatment combinations) on growth (plant height, number of leaves, number of branches, leaf area), yield, yield attributes (number of pods plant-1 , pod length, pod weight), chlorophyll a, b, and carotene contents, and resistance of okra plants (cv. Baladi) to powdery mildew disease. All treatments were significantly reduced powdery mildew infection with highest resistance observed with PAA+PS or PAA+PB, or PB+PAA treatments. Growth characteristics were enhanced by most treatments with the highest increases detected with singular PS or PAA treatments and with sequential PB+PS treatment. PS was superior in increasing the number of leaves, branching number, and leaf areas. The only treatments that significantly increased total yield were PAA+PB, PAA, PS, PS+PAA, and PAA+PS with the former two treatments giving the highest total yield. In conclusion, foliar spraying of okra with singular or sequential treatments with PS, PAA, and PB significantly improved plant resistance to powdery mildew infection. Nevertheless, singular PS or PAA treatments as well as sequential PB+PS, PAA+PS, PS+PAA, and PAA+PB treatments were the most effective in improving growth and yield while controlling powdery mildew disease.

“…It has been noted that the presence of too high concentrations of chemical disinfectants in hydroponic solutions can lead to stunted growth, root, and leaf damage, and effects on nutritional quality (Vines et al, 2003;Premuzic et al, 2007). Similarly, crop damage can occur when irrigating fields with reconditioned wastewater that contains disinfectant residuals, which is for example generally the case with wastewater containing more than 5 mg/L chlorine (Pedrero et al, 2010).…”

This paper comprises a selection tool for water disinfection methods for fresh produce pre- and postharvest practices. A variety of water disinfection technologies is available on the market and no single technology is the best choice for all applications. It can be difficult for end users to choose the technology that is best fit for a specific application. Therefore, the different technologies were characterized in order to identify criteria that influence the suitability of a technology for pre- or postharvest applications. Introduced criteria were divided into three principal components: (i) criteria related to the technology and which relate to the disinfection efficiency, (ii) attention points for the management and proper operation, and (iii) necessities in order to sustain the operation with respect to the environment. The selection criteria may help the end user of the water disinfection technology to obtain a systematic insight into all relevant aspects to be considered for preliminary decision making on which technologies should be put to feasibility testing for water disinfection in pre- and postharvest practices of the fresh produce chain.

“…Recently, Ktitorova et al (2002) suggested that the inhibitory effect of salt stress on L o of wheat (Triticum aestivum) plants might be mediated by H 2 O 2 produced in the roots during salt exposure. The inhibition of tomato L o by the chemical disinfectant peracetic acid may also be mediated by H 2 O 2 (Vines et al, 2003). In the same way, H 2 O 2 generated during chilling could be the cause of the inhibition of L o in chilling-sensitive species.…”

The Role of Aquaporins and Membrane Damage in Chilling and Hydrogen Peroxide Induced Changes in the Hydraulic Conductance of Maize Roots

et al. 2005

When chilling-sensitive plants are chilled, root hydraulic conductance (L o ) declines precipitously; L o also declines in chillingtolerant plants, but it subsequently recovers, whereas in chilling-sensitive plants it does not. As a result, the chilling-sensitive plants dry out and may die. Using a chilling-sensitive and a chilling-tolerant maize genotype we investigated the effect of chilling on L o , and its relationship to osmotic water permeability of isolated root cortex protoplasts, aquaporin gene expression, aquaporin abundance, and aquaporin phosphorylation, hydrogen peroxide (H 2 O 2 ) accumulation in the roots and electrolyte leakage from the roots. Because chilling can cause H 2 O 2 accumulation we also determined the effects of a short H 2 O 2 treatment of the roots and examined the same parameters. We conclude from these studies that the recovery of L o during chilling in the chilling-tolerant genotype is made possible by avoiding or repairing membrane damage and by a greater abundance and/or activity of aquaporins. The same changes in aquaporins take place in the chilling-sensitive genotype, but we postulate that membrane damage prevents the L o recovery. It appears that the aquaporin response is necessary but not sufficient to respond to chilling injury. The plant must also be able to avoid the oxidative damage that accompanies chilling.Many crop species such as maize (Zea mays) that originate in tropical regions are sensitive to low temperatures and grow poorly after exposure to a cold period (Miedema, 1982). Below 12°C to 14°C, maize seedlings are damaged as a result of leaf dehydration and an inhibition of photosynthesis. Such damage may result in the plant's death (Miedema, 1982). With the wide utilization in temperate climates of crops of tropical origin, the adverse effect of chilling is an important agricultural problem the physiological basis of which can be elucidated. Cold-tolerant species increase their root hydraulic conductance (L o ) during low temperature periods (Fennell and Markhart, 1998;Bigot and Boucaud, 2000), and the same phenomenon has been observed in a chilling-tolerant genotype of maize (Aroca et al., 2001b(Aroca et al., , 2003b. The water deficit in the aerial parts of a chilling-sensitive maize genotype is caused in part by low temperature inhibition of L o (Aroca et al., 2001b(Aroca et al., , 2003b. The recovery of L o in cold-tolerant plants may be associated with an increase in the activity or the abundance of aquaporins in the plasma membranes of root cells. On the other hand, the opposite may happen in cold-sensitive species: aquaporins may be down-regulated or inactivated (Aroca et al., 2001b;Sanders and Markhart, 2001;). Lee et al. (2004b) recently showed that in cucumber (Cucumis sativus), a cold sensitive species, a brief exposure to low temperature reduces root pressure, hydraulic conductivity, and active nutrient transport. These authors also postulated that changes in the activity of aquaporins underlie the changes in hydraulic conductivity.Response to cold,...
