“…In modern agriculture, the hydroponic device is the growing process of the plant root cultivated in the nutrient-rich solutions, such as the official Real-Time Operating System (RTOS) for ARM Cortex-M microcontroller [15]. The hydroponic devices were used to produce "Biquinho" pepper with brackish water [16]. However, there are few reports on soilless cultivation of medicinal plants, such as Coptis chinensis Franch.…”

Astragalus membranaceus Bge. var. mongolicus (Bge.) Hsiao roots are widely used as raw materials of medicine. Due to the limited arable land, cultivating medicinal plants hydroponically is increasingly concerned. However, whether the quality of A. membranaceus grown hydroponically is better than that produced in a field is still unknown. In this study, we designed an intelligent hydroponic device for A. membranaceus, and quality of the medicinal plant cultivated by this device was compared with that cultivated in the field. Results showed that hydroponics significantly increased effective components in A. membranaceus when compared with field. Specifically, astragaloside IV contents in A. membranaceus grown hydroponically for four weeks were higher than those cultivated in the field for two years. The biomass is not significantly different between four-week hydroponics and annual cultivation. Therefore, hydroponics with our intelligent device can be used for the sustainable production of A. membranaceus in the future.

“…Through the data of total production per plant in the two cycles, the tolerance level of sour passion fruit to salt stress was determined based on the relative yield, using the plateau followed by a linear decline model proposed by Maas and Hoffman [ 74 ]. The model parameters were fitted by minimizing the square of errors with the Microsoft Excel Solver tool, as reported by Bione et al [ 84 ]. The plants were classified according to the degree of tolerance, adopting the criterion of reduction in relative yield Fageria and Gheyi [ 75 ], with four levels of classification: T (tolerant; decrease between 0 and 20%), MT (moderately tolerant; decrease between 20% and 40%), MS (moderately sensitive; decrease between 40% and 60%), and S (Sensitive; decrease > 60%).…”

Brazil stands out as the largest producer of sour passion fruit; however, the water available for irrigation is mostly saline, which can limit its cultivation. This study was carried out with the objective of evaluating the effects of salicylic acid in the induction of tolerance in sour passion fruit to salt stress. The assay was conducted in a protected environment, using a completely randomized design in a split-plot scheme, with the levels of electrical conductivity of the irrigation water (0.8, 1.6, 2.4, 3.2, and 4.0 dS m−1) considering the plots and concentrations of salicylic acid (0, 1.2, 2.4, and 3.6 mM) the subplots, with three replications. The physiological indices, production components, and postharvest quality of sour passion fruit were negatively affected by the increase in the electrical conductivity of irrigation water, and the effects of salt stress were intensified in the second cycle. In the first cycle, the foliar application of salicylic acid at concentrations between 1.0 and 1.4 mM partially reduced the harmful effects of salt stress on the relative water content of leaves, electrolyte leakage, gas exchange, and synthesis of photosynthetic pigments, in addition to promoting an increase in the yield and quality parameters of sour passion fruit.

The present study aimed to evaluate the effects of the foliar application of hydrogen peroxide on the attenuation of salt stress on the growth, photochemical efficiency, production and water use efficiency of ‘All Big’ bell pepper plants. The experiment was conducted under greenhouse conditions in Campina Grande, PB, Brazil. Treatments were distributed in a randomized block design, in a 5 × 5 factorial scheme, corresponding to five levels of electrical conductivity of irrigation water (0.8, 1.2, 2.0, 2.6 and 3.2 dS m−1) and five concentrations of hydrogen peroxide (0, 15, 30, 45 and 60 μM), with three replicates. Foliar application of hydrogen peroxide at concentration of 15 μM attenuated the deleterious effects of salt stress on photochemical efficiency, biomass accumulation and production components of bell pepper plants irrigated using water with an electrical conductivity of up to 3.2 dS m−1. Foliar spraying of hydrogen peroxide at a concentration of 60 μM intensified the effects of salt stress. The ‘All Big’ bell pepper was classified as moderately sensitive to salt stress, with an irrigation water salinity threshold of 1.43 dS m−1 and a unit decrease of 8.25% above this salinity level.
