“…This is consistent with the experimental conclusions of Li et al [40], Li et al [41], and Wu et al [16]. The appropriate amount of soluble organic fertilizer can increase soil nutrients and enhance the root vitality of crops so as to effectively promote plant growth, improve tomato yield, and increase water use efficiency [13,42,43]. Moistube irrigation increases yield more than drip irrigation and has higher water use efficiency.…”

A reasonable fertilization rate and appropriate irrigation technology can lead to the green development of greenhouse tomatoes. The purpose of this study was to explore suitable irrigation technology for greenhouse tomatoes and the appropriate application rate of the soluble organic fertilizer and inorganic fertilizer combination. In 2021 and 2022, the effects of different irrigation techniques and fertilization treatments on tomato plant growth, fruit quality, yield, and efficiency were studied. The irrigation techniques in this study were drip and Moistube irrigation, and there were seven types of fertilization treatment, namely, no fertilization treatment (CK); low-volume (T1, 330 kg/hm2), medium-volume (T2, 660 kg/hm2), and high-volume inorganic fertilizer treatments (T3, 990 kg/hm2); and three inorganic fertilizer treatments of low-volume inorganic fertilizer (T1, 330 kg/hm2) combined with low-volume (F1, T1 + 75 kg/hm2), medium-volume (F2, T1 + 225 kg/hm2), and high-volume (F3, T1 + 375 kg/hm2) organic fertilizer. A total of 14 experimental treatments were implemented for irrigation and fertilization. The results of the two-year experiment show that the growth effect on the height, stem diameter, and leaf area index of tomato plants was the best using the treatment of low-concentration inorganic fertilizer combined with medium-concentration organic fertilizer with Moistube irrigation and drip irrigation. Using the two irrigation methods, the application of soluble organic fertilizer increased the yield and improved the fruit quality of the tomato. The maximum yield increased by 28.52%, the soluble sugar content increased by 14.49%, the vitamin C content increased by 45.04%, and the lycopene increased by 18.79%. The entropy-weight TOPSIS model was used to comprehensively evaluate 14 evaluation objects with different irrigation methods and fertilization treatments. The results of the two-year experiment show that the best fertilization treatment under Moistube irrigation and drip irrigation conditions was low-concentration inorganic fertilizer combined with medium-concentration soluble organic fertilizer, which was combined with the best fertilization treatment, and the most suitable irrigation method for greenhouse tomato cultivation in the Loess Plateau was Moistube irrigation. The results of this study also provide practical experience and theoretical support for adaptive irrigation and the integrated management of water and fertilizer.

“…Studies have shown that cultivation using different substrates can have different effects on the growth and development of plants [ 31 , 32 , 33 , 34 ]. In a field experiment, four mixed soilless substrates were used for strawberry cultivation, and the results showed that strawberry plants grew most vigorously in 100% coconut coir, and the fruit yield was not significantly different from that under conventional soil cultivation [ 33 ].…”

“…The higher N content in the FPB substrate may have promoted fruit development. Fallah et al [ 34 ] found that the fruit dimensions and weight of cherry tomatoes increased with increasing N content in the nutrient solution. In addition, the color of the fruit also showed significant differences.…”

“…This also indicates that the levels of mineral elements in the FPB substrate, especially the N and K levels, may be in a relatively moderate concentration range, which can promote plant growth and facilitate improvements in fruit quality. The total soluble solids content of fruit can be improved by the treatment with appropriate an N/K ratio [ 34 ]. Polyphenols are important secondary metabolites in blueberries that can protect plants from a variety of biological and abiotic stresses [ 1 , 38 ].…”

With improving living standards, traditional blueberry planting modes cannot meet commercial demands, and blueberry cultivation with soilless substrate has become a popular solution in the blueberry industry. In this study, different soilless substrate treatments were found to markedly influence fruit appearance and intrinsic quality. The fruit in the 50:50 peat/pine bark (v/v) (FPB) treatment group had the maximum single fruit weight, largest vertical diameter, and brightest color, as well as the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) value, solid-acid ratio and anthocyanin content. The fruit in the 50:50 pine bark/rice husk (v/v) (FBR) treatment group had the highest total phenol and flavonoid levels, largest drip loss value, and lowest total pectin content and firmness value. Metabolomic analysis showed that flavonoid, carbohydrate, and carbohydrate conjugate, and amino acid, peptide, and analog levels were significantly different between groups. Fruit in the FPB group had the highest sucrose, D-fructose 1,6-bisphosphate, salidroside, tectorigenin, naringenin chalcone, trifolirhizin, and galangin contents. The increase in the relative expression of phenylalanine (Phe) promoted the synthesis of fruit polyphenols in the FBR group. Our results provide new insights into the effects of different substrates on the quality of blueberries and a reference for the soilless substrate cultivation of blueberries.

“…The production and consumption of tomato (Solanum lycopersicum L.) fruit are considerably high because of their rich nutritional and mineral value (Dorais et al, 2008;Fallah et al, 2021;Vélez-Terreros et al, 2021). Tomato fruit contain a variety of primary and secondary metabolites, including soluble carbohydrates, organic acids, vitamins A and B, and lycopene, which are also Alteration of Fruit Quality Attributes and Cell Wall-Degrading Enzymatic Activities in Cluster Tomatoes After Combination Treatment ... known as an antioxidant compound (Raiola et al, 2014;Carillo et al, 2019).…”

This study evaluates the combined effects of 1-methylcyclopropene (1-MCP) and modified atmosphere packaging (MAP) on the quality of cluster-type tomato cultivars. Here, we analyze the physiological and biochemical alterations that affect fruit characteristics during cold storage, including knuckle detachment force, ethylene production rate, and cell wall-degrading enzymatic activity. The optimum concentration of 1-MCP fumigation treatment to regulate fruit ripening after harvest was 1 μL•L -1 . During storage at 10°C, the fruit of the 'Amoroso' cultivar performed better than those of the 'Campari' and 'Aranca' cultivars in terms of ethylene production, soluble solids content (SSC), and pericarp tissue firmness. The combination treatment with 1-MCP and MAP reduced the SSC level and retained the pericarp tissue firmness and knuckle detachment force in 'Amoroso' fruit in cold storage. Polypropylene (PP) MAP treatment alone did not affect the response to ethylene production during cold storage as significantly as the treatment with both 1-MCP and PP MAP. However, treatment with both 1-MCP and PP MAP retained the knuckle detachment force and delayed the alteration of O 2 and CO 2 composition, in contrast to PP MAP treatment alone. In addition, the enzymatic activities of polygalacturonase and cellulase remained unchanged when treated with 1-MCP and PP MAP. Therefore, combined application of 1-MCP and PP MAP is highly effective for retaining fruit quality of cluster-type tomato cultivars during cold storage.
