Seedlings of Citrus grandis (L.) Osbeck cv. Tuyou were irrigated daily for 5 months with nutrient solution containing 0 (control), 0.2, 0.6 or 1.6 mM aluminum (Al) from AlCl3·6H2O. Shoot growth was more sensitive to Al toxicity than root growth, gas exchange, chlorophyll (Chl) concentration, polyphasic Chl a fluorescence (OJIP) induction and related parameters. Leaves Al-treated plants showed decreased CO2 assimilation yet intercellular concentration increased ribulose-1,5-bisphosphate...
To determine the molecular epidemiology of extended-spectrum β-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR) in Escherichia coli isolated from farmed fish China. E. was gut samples throughout Guangdong province tested for presence β-lactamase genes PMQR-encoding using PCR DNA sequence analysis. Co-transfer plasmids encoding ESBLs as well PMQR determinants explored by conjugation into coli. A total 218 non-duplicate were recovered samples. β-Lactamase identified 19 (17%)...
We explored the effects of different light intensities and photoperiods on growth, nutritional quality antioxidant properties two Brassicaceae microgreens (cabbage Brassica oleracea L. Chinese kale alboglabra Bailey). There were experiments: (1) four photosynthetic photon flux densities (PPFD) 30, 50, 70 or 90 μmoL·m-2·s-1 with red:blue:green = 1:1:1 light-emitting diodes (LEDs); (2) five 12, 14, 16, 18 20 h·d-1. With increase intensity, hypocotyl length cabbage shortened. PPFD μmol·m-2·s-1...
With far-red-light supplementation (3 W·m-2, and 6 W·m-2), the flower budding rate, plant height, internode length, display, stem diameter of Chinese kale were largely elevated, as well leaf morphology such width, petiole area. Consequently, fresh weight dry edible parts markedly increased. The photosynthetic traits enhanced, mineral elements accumulated. To further explore mechanism that far-red light simultaneously promoted vegetative growth reproductive kale, this study used RNA...
Three different LED spectra (W: White light; WFR: W + far-red WB: blue light) with similar photosynthetic photon flux density (PPFD) were designed to explore the effects of supplementary and lights on leaf color, biomass phytochemicals two cultivars red-leaf lettuce ("Yanzhi" "Red Butter") in an artificial lighting plant factory. Lettuce plants under WB had redder color significantly higher contents pigments, such as chlorophyll a, b, (a b) anthocyanins. The accumulation health-promoting...
Different intensities of UV-A (6, 12, 18 μmol·m−2s−1) were applied in a plant factory to evaluate the combined influences supplemental and red blue light (Red:Blue = 1:1 at PPFD 250 μmol·m−2 s−1) on biomass, antioxidant activity phytochemical accumulation kale. Supplemental treatments (T1: 6 s−1, T2: 12 s−1 T3: resulted higher moisture content, pigment greater leaf area kale while T2 reached its highest point. treatment positively enhanced capacity, increased contents soluble protein, sugar...
Four light treatments (W: white light; EOD-B: end-of-day enhanced blue EOD-FR: supplementary far-red EOD-UV: ultraviolet-A light) were designed to explore the effects of (EOD) lightings (30 min before dark period) on leaf color, biomass and phytochemicals accumulation in two lettuce cultivars (Lactuca sativa cv. ‘Red butter’ ‘Green butter’) artificial plant factory. EOD-FR stimulated shoot cultivars, EOD-B suppressed growth but induced higher butter’. EOD generated brighter, greener yellower...
To explore the effect of different nutrient-solution depths on growth and phytochemicals accumulation kale, three depth treatments (De-1: 1 cm, De-2: 2 De-3: 3 cm) were applied in plant factory with artificial lighting. The maximum levels height, stem diameter, total leaf area, root length, surface area as well fresh dry weight shoot all noted De-2 at 24 days after treatment. Low (De-1 De-2) beneficial for chlorophyll nutrient ions uptake (N, P, K, Ca, S, Zn). However, there no obvious...
Ultraviolet-A (UVA) (315-400 nm) is an essential environmental signal that regulates plant development and affects phytochemicals biosynthesis, including glucosinolate biosynthesis. The effects of different UVA (380 ± 10 nm, 40 μmol/m2/s) exposure durations, 0 h/d (UV0), 6 (UV6) 12 (UV12), on the growth Chinese kale (Brassica alboglabra) under white 250 μmol/m2/s LEDs were investigated. durations influenced biosynthesis kale. Prolonging irradiation throughout cycle positively affected kale,...
For 10 days before harvest, supplemental 50 μmol m−2 s−1 blue light (430 nm) was applied in greenhouse conditions order to evaluate the influences of pre-harvest on both antioxidants and nutrition flower stalk Chinese kale during storage. The weight loss treated with generally lower than control Higher antioxidant activity maintained storage by light. Meanwhile, derived higher contents vitamin C, soluble protein, free amino acids, chlorophyll at harvest. samples exposed possessed values....
A potato tuber rot disease of unknown cause, affecting 5 to 15% the tuber, was observed at Gansu Province China in March 2010. Sunken, round, oval, or irregular lesions formed umbilicus buds tubers after 30 days storage 4°C. These gradually expanded form khaki, lavender sunken ranging from 1 3 cm. Small black bodies were center 45 days. Twenty-six diseased collected and surface sterilized with 75% alcohol. Diseased tissue then directly transferred dextrose agar (PDA) medium for isolation...
As an indispensable element in the morphology and phytochemical profile of plants, UV-A has proved to help promote growth quality kale. In this study, supplementation different photoperiods (light period supplemental UVA = LS, dark DS, light-dark LDS) contributed yielding greater biomass production (fresh weight, dry plant moisture content), thus improving (plant height, stem diameter, etc.) promoting higher phytochemicals content (flavonoids, vitamin c, etc.), especially glucosinolates. To...
The precise control of the light spectrum in plant factory systems enables targeted manipulation vegetable primary and secondary metabolites, including health-promoting compounds that benefit human body. This study applied transcriptomic metabolic approaches to investigate comprehensive molecular events lettuce (Lactuca sativa L. cv ‘Red butter’) grown under white LED (CK), supplementary far-red (FR-3: 3 W·m−2 FR-6: 6 W·m−2) blue lights (B-12: 12 B-24: 24 W·m−2). A total 1577 DEGs...
The nutritional quality and biomass of various sprouts can be enhanced by Zn red-blue light, especially the Brassica sprouts. However, combined effects this two on are rarely reported. In study, different concentrations (0, 1.74, 3.48, 10.43 17.39 mM) were with ratios light-emitting diodes (LEDs) (R: B = 1:2, 1R2B; R: 2:1, 2R1B, at 70 μmol m−2 s−1 PPFD, 14 h/10 h, light/dark) to investigate their mutual growth, mineral elements, in flowering Chinese cabbage (FCCS). Fresh weight, dry contents...
Abstract The development of a new method to accurately and non-destructively identify the quality vegetables cultivated under different light treatments is urgent because traditional methods identification are time-consuming, costly destructively. A based on hyperspectral imaging technology combined with machine learning was developed in this paper rapidly kale plant factory. UV-A supplementation photoperiods used regulate by improving contents moisture, photosynthetic pigments...
