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 o...

Plant-derived protein hydrolysates (PHs) have gained prominence as plant biostimulants because of their potential to increase the germination, productivity and quality of a wide range of horticultural and agronomic crops. Application of PHs can also alleviate the negative effects of abiotic plant stress due to salinity, drought and heavy metals. Recent studies aimed at uncovering the mechanisms...

The use of biostimulants in modern agriculture has rapidly expanded recent years, owing to their beneficial effects on crop yield and product quality, which have come under the scope intensive research. Accordingly, present study we appraised efficacy two plant-derived biostimulants, legume-derived protein hydrolysates Trainer® (PH), tropical plant extract Auxym® (TPE) lettuce cultivars (green ...

Over time plants developed complex mechanisms in order to adapt themselves to the environment. Plant innate immunity is one of the most important mechanisms for the environmental adaptation. A myriad of secondary metabolites with nutraceutical features are produced by the plant immune system in order to get adaptation to new environments that provoke stress (stressors). Hormesis is a phenomenon...

The rare earth element (REE) cerium (Ce) can act as a biostimulant in diverse crop plants. effects of 0, 5, 10, and 15 µM Ce (supplied CeCl3 7H2O) on seed germination the initial growth tomato (Solanum lycopersicum L.) cv. Vengador were evaluated. After 12 h imbibition, weight seeds treated with was 37.5% greater than that observed control. index 5 100% (101.93%), though when applying 10 this 1...

Abstract Background In this research, the effects of exogenous application certain biostimulants [amino acid (AA), humic (HA), fulvic (FA), and seaweed extract (SE)] on fruit yield quality, leaf mineral contents, some critical physio-chemical characteristics grapevine ( Vitis vinifera L.) cv. ‘Yaghouti’ were investigated under well-watered (WW) drought-stressed (DS) conditions. Results Drought ...
