The treatment of duckweed with a plant biostimulant or a safener improves the plant capacity to clean water polluted by terbuthylazine

Plant Biostimulants: Importance of the Quality and Yield of Horticultural Crops and the Improvement of Plant Tolerance to Abiotic Stress—A Review

“…Hydrolysis Product Enzymatic (alfalfa hay, pulses, and vegetable or fruit waste) and chemical (feathers, bone meal, casein, collagen from skins, animal tissue, or fish waste) Increase in yield [32] Increase in nitrogen and phosphorus content in leaves and macro-and micronutrients [33,34] Increase in protein content in cereal grains [33] Protection against biotic and abiotic stresses [35] Increased soil fertility through the development of soil microorganisms [36] Anaerobic Digestion Product Plant, animal, and lignin biomass Call of the auxin-like effect [23,37] Improving the availability of nutrients [31] Biopreparations from Marine Algae Ascophyllum nodosum, Sargassum wightii, Ecklonia maxima, Enteromorpha intestinalis, Gelidium pectinutum…”

Safeners improve early‐stage chilling‐stress tolerance in sorghum

“…In rice, a combination of safener and hormone treatment under abiotic stress conditions resulted in an additive effect by enhancing plant growth and tiller number (Dashevskaya et al., 2013). A safener‐induced glutathione S ‐transferases catalysed ROS scavenging mechanism, combined with additional signalling and antioxidant mechanisms increased tolerance to chilling stress and other abiotic stresses (Dashevskaya et al., 2013; Kocsy et al., 2001; Panfili et al., 2017; Panfili et al., 2019; Taylor et al., 2013). Similarly, in the present study, we hypothesize that chilling‐stress tolerance enhanced by the safener combination of benoxacor, oxabetrinil, fluxofenim and NA could be due to enhanced ROS scavenging mechanisms, as eluded to in previous studies (Baek et al., 2019; Dean et al., 1990; DeRidder et al., 2002; Gronwald et al, 1987; Xu et al., 2002).…”

“…For example, safeners are agrochemicals that decrease herbicide injury in cereal crops without reducing efficacy on target weeds, and function by increasing the expression of defence genes and enzymes involved in herbicide detoxification mechanisms (Riechers et al., 2010). Further, safener treatments are associated with detoxifying cytotoxins and stress‐induced reactive oxygen species (ROS), and as a result lead to increased protection from herbicides, pollutants, and abiotic stresses (Dashevskaya et al., 2013; DeRidder et al., 2002; Jablonkai, 2013; Panfili et al., 2017; Panfili et al., 2019; Riechers & Green, 2017; Riechers et al., 2010; Taylor et al., 2013; Ye et al., 2019). Among the many approaches used to enhance abiotic stress tolerance in plants, exogenous application of agrochemicals such as safeners is considered a new strategy (Abu‐Qare & Duncan, 2002; Bianchi et al., 2020; Dashevskaya et al., 2013; Taylor et al., 2013).…”

Biogenic ZnO Nanoparticles Synthesized Using a Novel Plant Extract: Application to Enhance Physiological and Biochemical Traits in Maize

“…In this respect, Lemna minor (duckweed), a small floating species used in ecological and phytoremediation studies, is of particular interest [ 24 , 25 , 26 ]. This species, native to several continents, is characterized by rapid growth and the ability to survive adverse environmental and climatic conditions [ 27 ].…”

“…Therefore, this plant could represent an attractive renewable feedstock for many different applications [ 28 ]. Besides, duckweed is highly resistant to organic and inorganic toxic substances [ 29 ], thanks to its high content of antioxidants, which are easily inducible in response to abiotic stresses [ 23 , 25 ].…”
