“…The RWC maintenance associated with gs reduction and osmotic adjustment was reported for Nicotiana glauca (Gonzáles et al, 2012). The high values of RWC exhibited in plants with low irrigation volumes here could also be due to the osmotic adjustment, which has been reported for lettuce (Lucini et al, 2015).…”

“…Amanda et al (2009) confi rmed the increase of baby leaf lettuce yield after treatment with Actiwave ® biostimulant with betaine, alginic acid, and caidrine, a derivative of vitamin K1. Recently, Lucini et al (2015) have shown that L. sativa L. cv. Regina di Maggio treated with Trainer, a biostimulant with plant (L) amino acids, was more resistant to yield and biomass reduction caused by stress conditions.…”

“…Biostimulants include diverse substances and microorganisms that enhance plant growth (Calvo et al 2014). The effects of several biostimulants on plant growth from spring until autumn in the Mediterranean region have been investigated so far (Vernieri et al 2002, Amanda et al 2009, Lucini et al 2015. Regarding the winter season, Johnstone et al (2005) and Tahsin (2010) investigated the effect of preplant phosphorous and nitrogen application, respectively, on lettuce yield, but this was not in the Mediterranean region.…”

-Lettuce production in the winter on the Adriatic coast, especially in a non-heated plastic tunnel, requires longer cultivation and is characterised by lower head mass and yield. In these conditions, the effect of biostimulant Bio-algeen S-90 and fertilizer Megagreen on the production of the traditional winter lettuce cultivar 'Four Seasons' was tested. Both treatments showed a positive effect on the growth and total yield of winter lettuce, and decreased the share of non-marketable yield. Bio-algeen S-90 treatment increased the plant height by 61.5%, and foliar treatment with Megagreen by 60.9%, as compared to the control treatment. Equally, both treatments resulted in higher leaf numbers (47.7% for Bio-algeen S-90 and 37.2% for Megagreen). The head mass of lettuce treated with Bio-algeen S-90 and Megagreen was 30.3% and 25.0% higher than in the control treatment, respectively. Megagreen contributed more to chlorophyll and carotenoid content, while Bio-algeen S-90 elevated the amount of vitamin C and dry matter. The pH value of lettuce juice decreased after Bio-algeen S-90, while the mineral content (N, P and K) did not differ between the tested treatments. Lower nitrate content was detected after both treatments. The obtained results elucidate the effect of Bio-algeen S-90 and Megagreen on "low input" lettuce production.

“…Lettuce (Lactuca sativa L.) is particularly salt sensitive and the addition of plant-derived protein hydrolysates improved fresh yield, dry biomass, and root dry weight as well as increased concentrations of osmoyltes, glucosinolates and the composition of sterols and terpenes [52]. Hydrolysates have applications for trees, which require considerable investment costs and can be vulnerable to drought.…”

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.
