“…In this sense, Ibrahim et al [11] reported an increase of 1.22 to 1.82 mg GAE/g extract when applying 0 to 270 kg of K + /ha in Labisia pumila Benth, and also obtained similar results for flavonoids, reporting values from 0.68 to 0.94 mg g −1 of rutin in leaves of this plant by increasing K + . Flanigan and Niemeyer [13] found values from 13.1 to 26.9 mg GAE/g DW for ten basil cultivars.…”

“…There was also a significant positive correlation (r = 0.979) among the content of flavonoids and anthocyanins, since anthocyanins are classified as a class of flavonoids derived ultimately from phenylalanine [27], indicating that the increase of flavonoids is influenced by the increase of anthocyanins. Vitamin C also showed a significant positive correlation with total flavonoids (r = 0.708) and anthocyanins (r = 0.682), which could be explained in terms of the synthesis of vitamin C, produced from nonstructural carbohydrates compounds and phenylpropanoids precursors [11]. The antioxidant capacity had a positive correlation with flavonoids (r = 0.621), and anthocyanins (r = 0.655), but a low correlation with TPC (r = 0.549).…”

“…The response of K + to these compounds might be due to a maximum accumulation of nonstructural carbohydrates given by translocation of the ion K + to formation of phenyl-propanoids [11]. Once in the cytosol, K + can cross the tonoplast through conveyors or channels which are responsible for its influx into vacuoles, while channels mainly mediate its outflow to the cytosol by antiporters which catalyze the electroneutral exchange of K + and H + using an electrochemical gradient produced by H + -ATPase present in the plasma membrane of cell organelles [32,33].…”

Abstract:The potential impact of increased levels of potassium (K + ) in hydroponic solution on the production of bioactive compounds, which provide added value to products, is relevant for local economy and human health. This research pursues assessing different levels of K + on the nutrition of basil, an important aromatic crop in the arid region of La Laguna, northern México, where water scarcity demands the conversion from open-field agriculture to hydroponics. A randomized complete block design with a factorial arrangement (3 × 4) was used to determine the content of nutraceutical components, including polyphenolic compounds, flavonoids, anthocyanins, vitamin C, chlorophylls, and the antioxidant capacity of three varieties of hydroponic basil, with four doses of K + in the nutrient solution, 7, 9, 11 and 13 mmol L −1 . The analysis of variance showed significant differences (p ≤ 0.001) in most of the response variables, caused by the genotype and doses of K + . The antioxidant capacity of assessed cultivars was improved when doses of K + were increased in the nutrient solution. Furthermore, the antioxidant capacity was positively correlated to the content of flavonoids (r = 0.621), anthocyanins (r = 0.655) and total phenolic compounds (r = 0.549). In conclusion, the nutraceutical content was increased in basil when controlling K + in the nutrient solution.

“…12;2017 available for secondary biosynthetic routes. Whether it's true, then any environmental factor can trigger activation some pathway signal transduction lead to a response related to photosynthesis, growth and, consequently, primary metabolism could also affect the secondary metabolism (Ibrahim et al, 2012). Thus, occurrence of high night temperature can be considered one of these factors and in a future climate scenarios, the increase in global temperature as result of climate change could lead to changes in plant secondary metabolites biosynthesis altering the source-sink flow and consequently NSC accumulation and remobilization to grain filling; beyond plant capacity to respond to biotic and abiotic stresses could be altered.…”

Phenylalanine ammonia-lyase (PAL) which is considered to be one of the main lines of cell acclimation against stress in plants, non-structural carbohydrates (NSC) accumulation and chlorophyll fluorescence parameters were quantified in two rice genotypes as a function of two temperature regimes: 22/30 °C (control) and 28/30 °C night/day (high night temperatures -HNT), imposed from heading to milk stage. The rice cultivars chosen were Nagina22 (N22) and BRS Querência (BRS-Quer), which are genotypes tolerant and sensitive to high temperatures, respectively. BRS-Quer genotype highlighted more sensitive responses maintaining higher PAL and peroxidase levels on seventh and twenty-first days after stress imposing. On the other hand, this genotype showed levels of fructose, glucose and sucrose decreasingly across stress period whether compared to N22. Both genotypes showed similarity for most of the chlorophyll fluorescence parameters. However, the photosynthesis induction curve highlighted that HNT caused decreases in some photochemical quenching of fluorescence as well as increases of non-phochemical quenching, affecting more prominently BRS-Quer genotype. N22 maintained unaltered the spikelet sterility and 1000-grain weight across temperature regimes showing a consistent trend with its stem NSC accumulation during stress period. The higher availability of soluble sugars shown by N22 at the end of stress period could be unloaded in spikelet formation and grain fillings contributing in their lower sterility rate and greater 1000-grain weight stability across the environments. These results indicate that selecting genotypes with higher capacity to stem NSC translocation beyond accumulation at HNT could lead to more grain yield stability in future climate scenarios.

Combined effects of cations in fertilizer solution on antioxidant content in red lettuce (Lactuca sativa L.)

et al. 2021

BACKGROUND Red lettuce is consumed worldwide because it is a great source of natural antioxidants. To design a fertilizer formula to boost its nutritional value, this research simultaneously studied the effects of significant cations among the macronutrients for plant growth (K, Mg and Ca) and the effects of the electrical conductivity (EC) of the nutrient solution on phenolic compound production and mass productivity of hydroponically grown red lettuce. RESULTS Red lettuce grown under the control treatment provided the highest mass productivity (under low‐stress conditions). The highest antioxidant content, measured as milligrams of phenolic compounds per gram dry weight (at a high‐stress condition) via both Folin–Ciocalteu and HPLC analyses, was observed in growth media containing 100 ppmK : 20 ppm Mg : 70 ppm Ca (with EC equal to 1241 μS cm−1). It was found that EC within the range of this examination had no significant effect on the mass productivity or on phenolic compound productivity. The phenolic compound productivity, defined as the amount of phenolic compounds produced per unit of planting area per unit of time, was optimized with the optimum formula for maximum phenolic compound productivity of 90 ppm K : 29 ppm Mg : 77 ppm Ca, or a corresponding EC of 1307 μS cm−1. CONCLUSIONS The study demonstrates that health‐promoting nutrient production in red lettuce could be stimulated in a practical manner by adjusting the cation concentrations in fertilizer solution. © 2021 Society of Chemical Industry
