“…Although extra-large fruits were obtained in all treatments, the highest yield was obtained with the EOW treatment (7.72 ± 2.27 kg), as mentioned above. There are studies, such as that of Sugiharta et al [46], that have reported that the application of electrolyzed water using Fe electrodes influences the weight, number of leaves, and stem thickness in spinach grown under a hydroponic system. In addition, Zhou et al [47] mention that slightly acidic electrolyzed water (pH = 5.0) can improve plant growth and photosynthetic efficiency in lettuce.…”

Bacterial speck disease in tomato crops is caused by Pseudomonas syringae pv. tomato. Chemical control is mainly used for the control of phytopathogens, which carries a risk for both human health and the environment, making it necessary to search for environmentally friendly alternatives, such as the use of electrolyzed water. In the present study, preventive treatments were applied to tomato plants of the saladette variety. The treatments employed were electrolyzed oxidizing water (EOW), electrolyzed reduced water (ERW), a commercial bactericide (Kasumin), and untreated plants as the base control. During the vegetative stage, the disease severity, stem diameter, number of leaves, and number of clusters were determined. In addition, the soluble solids (°Brix), titratable acidity (TA), pH, color, polar and equatorial diameter, weight, and weight loss of the harvested fruit were determined. According to the results, the lowest severity was obtained in the plants treated with oxidizing water, achieving results similar to those achieved with the commercial bactericide Kasumin. It can be concluded that oxidizing water can be applied to tomato crops since its effect is similar to that of Kasumin, but without affecting the growth and development of the crop. Moreover, it is environmentally friendly.

“…Considering that iron is a noninert electrode, the reaction occurs at the anode [10]. When an electric current is applied to the electrolysis cell, the iron anode oxidizes to form Fe 2+ ions, according to equation ( 2), considering the Fe electrode is reactive [11].…”

Water - in the context of an inland water source - is complex when used as an object of research. Often when using river water samples, researchers struggle to find the desired composition. Therefore, a simple and controlled method is needed to produce test samples with specific substance compositions. This study aims to use electrolysis to produce artificial heavy metal waste. Iron (Fe) and copper (Cu) provided the electrodes and water the electrolytes. Electrolysis of water with Fe electrodes produced Fe3+ ions and Fe(OH)3 precipitation. Electrolysis of water with Cu electrodes produced Cu2+ ions and Cu(OH)2 precipitation. Electrolyte samples were collected at intervals of 30 min for 180 min and were tested with atomic absorption spectroscopy. Fe and Cu concentrations increased during electrolysis. Electrolysis can therefore be used to produce artificial heavy metal waste cheaply and on a small scale.

“…Compared with the traditional soil planting, hydroponics technology has the advantages of short growth cycle, effective resource saving, flexible cultivation condition, and reduced infection rate of diseases and pests ( Shehzad et al, 2021 ). In addition, hydroponic method is capable of helping in the observation and management, as it can accurately control the growth and development process of plants ( Sugiharta et al, 2019 ). Researchers have studied the phenotypic characteristics of plants through hydroponic method in the cultivation processes of diverse fruit species.…”

Phosphorus (P) is an essential macronutrient for the growth and development of fruit trees, playing an important role in photosynthesis, nucleic acid synthesis, and enzyme activity regulation. The plasticity of plant phenotypic has been investigated in diverse species under conditions of P-deficiency or P-excess. Based on these researches, P level fluctuations in different species result in different characteristics of the response. Nevertheless, little is known about the response of pear seedling rootstock (Pyrus betulifolia Bunge) to the changing of P levels. To explore the effects of different levels of P on the growth of pear seedling rootstock, we performed the hydroponic assays to determine and analyze the biological indexes including growth parameters, photosynthetic rate, root and shoot morphological traits, and concentrations of macro- and micronutrients. The results show that either deficiency or excess of P inhibited the growth and development of pear seedling rootstock. Root growth (down 44.8%), photosynthetic rate (down 59.8%), and acid phosphatase (ACP) activity (down 44.4%) were inhibited under the P-deficiency conditions (0mM), compared with normal P conditions (1mM). On the other hand, dark green leaves, suppression of root elongation (down 18.8%), and photosynthetic rate (down 25%) were observed under regimes of excessive P, compared with normal P conditions (1mM). Furthermore, the root concentration of not only P, but also those of other mineral nutrients were affected by either P treatment. In brief, these results indicated that a careful choice of P fertilizer supply is crucial to ensuring normal growth and development of pear seedling rootstock.
