Zusammenfassung
Biostimulants, are a diverse class of compounds including substances or microorganism which have positive impacts on plant growth, yield and chemical composition as well as boosting effects to biotic and abiotic stress tolerance. The major plant biostimulants are hydrolysates of plant or animal protein and other compounds that contain nitrogen, humic substances, extracts of seaweeds, biopolymers, compounds of microbial origin, phosphite, and silicon, among others. The mechanisms involved in the protective effects of biostimulants are varied depending on the compound and/or crop and mostly related with improved physiological processes and plant morphology aspects such as the enhanced root formation and elongation, increased nutrient uptake, improvement in seed germination rates and better crop establishment, increased cation exchange, decreased leaching, detoxification of heavy metals, mechanisms involved in stomatal conductance and plant transpiration or the stimulation of plant immune systems against stressors. The aim of this review was to provide an overview of the application of plant biostimulants on different crops within the framework of sustainable crop management, aiming to gather critical information regarding their positive effects on plant growth and yield, as well as on the quality of the final product. Moreover, the main limitations of such practice as well as the future prospects of biostimulants research will be presented. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

The combined and single effect of salinity and copper stress on growth and quality of Mentha spicata plants
Chrysargyris A., Papakyriakou E., Petropoulos S.A., Tzortzakis N. (2019)Copper is essential for plant growth, but in excess may cause adverse effects on plant physiology. Harmful effects are also caused by plant exposure to salinity (NaCl) due to the excessive use of fertilizers, soil degradation ... -
Overexpression of a biotic stress‐inducible pvgstu gene activates early protective responses in tobacco under combined heat and drought
Stavridou E., Voulgari G., Michailidis M., Kostas S., Chronopoulou E.G., Labrou N.E., Madesis P., Nianiou‐obeidat I. (2021)Drought and heat stresses are major factors limiting crop growth and productivity, and their effect is more devastating when occurring concurrently. Plant glutathione transferases (GSTs) are differentially expressed in ... -

Katsarou D., Omirou M., Liadaki K., Tsikou D., Delis C., Garagounis C., Krokida A., Zambounis A., Papadopoulou K.K. (2016)Glucosinolates (GSLs) are a highly important group of secondary metabolites in the Caparalles order, both due to their significance in plant-biome interactions and to their chemoprotective properties. This study identified ...
