“…Plant phenolics play pivotal roles in almost all plant growth and development processes with their antioxidant role. Phenolic compounds are especially produced by plants in response to environmental stresses ( Wagay et al, 2020 ). In the present study, ash application increased moderately the free phenolic acid content, particularly p -coumaric acid, in stem and leaves in the hybrid D24 ( Figure 4 ) while there was not a significant impact on the drought-sensitive hybrid P1921.…”

Wood ash as a soil amendment has gained wide spread acceptance in the recent years as a sustainable alternative to chemical fertilizers, although information regarding the effects of its application on maize growth and yield in the context of climate change and increasing drought severity is lacking till date. In the present study, field and pot trials were carried out at the experimental farm of the University of Padova at Legnaro (NE Italy) in a silty-loam soil in order to investigate the effects of soil amendment with wood ash (0.1% w/w, incorporated into the 0.2-m top soil) on the bioavailability of mineral elements and their uptake by maize. Characteristics analyzed included plant growth, leaf transpiration dynamics, and productivity in two contrasting hybrids, P1921 (drought sensitive) and D24 (drought tolerant). Wood ash contained relevant amounts of Ca, K, Mg, P, and S, and hazardous levels of Zn (732 mg kg−1), Pb (527 mg kg−1), and Cu (129 mg kg−1), although no significant changes in total soil element concentration, pH, and electrical conductivity were detected in open field. Ash application led to a general increasing trend of diethylene triamine penta-acetic acid (DTPA)-extractable of various elements, bringing to higher grain P in D24 hybrid, and Zn and Ni reductions in P1921 hybrid. Here, the results demonstrated that ash amendment enhanced shoot growth and the number of leaves, causing a reduction of harvest index, without affecting grain yield in both hybrids. The most relevant result was a retarded inhibition of leaf transpiration under artificial progressive water stress, particularly in the drought-tolerant D24 hybrid that could be sustained by root growth improvements in the field across the whole 0–1.5 m soil profile in D24, and in the amended top soil in P1921. It is concluded that woody ash can be profitably exploited in maize fertilization for enhancing shoot and root growth and drought tolerance, thanks to morphological and physiological improvements, although major benefits are expected to be achieved in drought tolerant hybrids. Attention should be payed when using ash derived by metal contaminated wood stocks to avoid any health risk in food uses.

“…Phenolic compounds (PCs) or polyphenols are among the unique plant metabolites that, due to their chemical properties, are able to neutralize free radical processes, thereby protecting cells from the action of reactive oxygen species (ROS) [ 3 , 18 , 19 , 20 ]. They are synthesized in almost all cells and are extremely diverse in their structure, properties, and functional activity [ 21 ].…”

“…They are considered biologically active plant metabolites exhibiting antiradical, antimutagenic, and anticarcinogenic activities [ 22 , 30 ]. The structural diversity and biological activity of PCs determines their uniqueness in the creation of many drugs, as well as the possibility of using them in the food, pharmaceutical, perfume, and cosmetic industries [ 19 , 31 ].…”

Effects of Hydrogen Peroxide on In Vitro Cultures of Tea (Camellia sinensis L.) Grown in the Dark and in the Light: Morphology, Content of Malondialdehyde, and Accumulation of Various Polyphenols

et al. 2022

Tea plants (Camellia sinensis L.) are phenol-accumulating crops that are widely used for public health. The healing effect of tea leaf products is due to the biosynthesis of such phenolic compounds (PCs) as flavans, which have P-vitamin capillary-strengthening activity. Due to their limited habitat and the value of their specialized metabolites of a phenolic nature, a promising approach is to establish in vitro cultures from them that retain the ability to form PCs, which is characteristic of ex vivo tea plants. The aim of this study was to investigate the effect of exogenic H2O2 (0.01 mM; 0.1 mM; 1 mM) on the growth, morphology, degree of stress response, and accumulation of various phenolic compounds in tea plant callus cultures of different ages (24 or 36 days) grown under different cultivation conditions (darkness or light). According to the results obtained, the H2O2 effect on tea callus cultures of different ages did not cause changes in their morphophysiological characteristics, both after 2 h of exposure (rapid response of callus culture, RRCC) and after 48 h (delayed response of callus culture, DRCC). The determination of the malondialdehyde (MDA) content, which serves as an indicator of changes in the level of lipid peroxidation (LPO) and the presence of stress responses in plant cells, indicated either its maintenance at the control level, a decrease, or an increase. All these effects depended on the growth conditions of the tea callus cultures (darkness or light), their age, the duration of exposure (rapid or delayed response), and the H2O2 concentration. Similar trends were noted for the total content of PCs as well as the amount of flavans, proanthocyanidins (soluble and insoluble forms), and lignin. The plant cell responses reflected changes in its adaptation programs, when specialized metabolites act as a target for the action of H2O2, thereby contributing to an increase in their resistance.

“…Most phenolic compounds naturally appear as conjugates with mono- and polysaccharides, coupled with one or more phenolic groups, and may also exist as functional derivatives like esters and methyl esters ( Naczk and Shahidi, 2003 ). Since phenols are a wide and diverse group of chemical combinations, they could be categorized in different ways according to the number of carbons in the molecule ( Table 1 and Table 2 ) ( Wagay et al., 2020 ).…”
