“…Application of Megafol to tomato plants under drought stress enhanced induction of a number of drought responsive genes such as tomato orthologs of RAB18 and RD29B. Treated plants also had higher fresh weight and relative water content under drought stress, indicating a protective effect on water status and stress responsive genes [43,71]. When hydrolysate-based biostimulants from alfalfa (Medicago sativa L.), containing triacontanol (TRIA) and indole-3-acetic acid (IAA), were applied to maize plants under salt stress, the protective effects were amplified.…”

The use of bioeffectors, formally known as plant biostimulants, has become common practice in agriculture and provides a number of benefits in stimulating growth and protecting against stress. A biostimulant is loosely defined as an organic material and/or microorganism that is applied to enhance nutrient uptake, stimulate growth, enhance stress tolerance or crop quality. This review is intended to provide a broad overview of known effects of biostimulants and their ability to improve tolerance to abiotic stresses. Inoculation or application of extracts from algae or other plants have beneficial effects on growth and stress adaptation. Algal extracts, protein hydrolysates, humic and fulvic acids, and other compounded mixtures have properties beyond basic nutrition, often enhancing growth and stress tolerance. Non-pathogenic bacteria capable of colonizing roots and the rhizosphere also have a number of positive effects. These effects include higher yield, enhanced nutrient uptake and utilization, increased photosynthetic activity, and resistance to both biotic and abiotic stresses. While most biostimulants have numerous and diverse effects on plant growth, this review focuses on the bioprotective effects against abiotic stress. Agricultural biostimulants may contribute to make agriculture more sustainable and resilient and offer an alternative to synthetic protectants which have increasingly falling out of favour with consumers. An extensive review of the literature shows a clear role for a diverse number of biostimulants that have protective effects against abiotic stress but also reveals the urgent need to address the underlying mechanisms responsible for these effects.

“…Automated greenhouse systems (LemnaTec system, http://www.lemnatec.com/) coupled with innovative image acquisition techniques (Phenoscope [43], RootReader3D [44], LemnaTec Scanalyzer 3D, http://www.lemnatec.de/scanalyzer_gh.htm), advanced image analysis pipelines (HTPheno [45]), and specific software applications (RootNav [46], Integrated Analysis Platform [47]) allow the nondestructive recording of a wide range of phenotypic traits over time (e.g. in barley [48] and tomato [49]). Nonetheless, efforts are still required to implement high-throughput and cost effective phenotyping in field conditions [50] and there is a great interest in drones or aircrafts as remote phenotyping sensor platforms able to monitor the field trials performance throughout the growing season (e.g.…”

“…Protein hydrolysates (PHs) are defined as mixtures of polypeptides, oligopeptides and amino acids that are manufactured from protein sources using partial hydrolysis (Schaafsma, 2009). The application of PHs has been shown to avoid or reduce production losses caused by unfavorable soil conditions and environmental stresses, such as temperature, drought, salinity and others (Botta, 2013; Petrozza et al, 2014; Lucini et al, 2015). Surprisingly, there exists very limited information about the effects of protein hydrolysates on herbicide-stressed plants.…”

Photosynthetic Performance of the Imidazolinone Resistant Sunflower Exposed to Single and Combined Treatment by the Herbicide Imazamox and an Amino Acid Extract

The herbicide imazamox may provoke temporary yellowing and growth retardation in IMI-R sunflower hybrids, more often under stressful environmental conditions. Although, photosynthetic processes are not the primary sites of imazamox action, they might be influenced; therefore, more information about the photosynthetic performance of the herbicide-treated plants could be valuable for a further improvement of the Clearfield technology. Plant biostimulants have been shown to ameliorate damages caused by different stress factors on plants, but very limited information exists about their effects on herbicide-stressed plants. In order to characterize photosynthetic performance of imazamox-treated sunflower IMI-R plants, we carried out experiments including both single and combined treatments by imazamox and a plant biostimulants containing amino acid extract. We found that imazamox application in a rate of 132 μg per plant (equivalent of 40 g active ingredient ha−1) induced negative effects on both light-light dependent photosynthetic redox reactions and leaf gas exchange processes, which was much less pronounced after the combined application of imazamox and amino acid extract.
