Journal ArticleDOI
Humic substances biological activity at the plant-soil interface: From environmental aspects to molecular factors
TL;DR: An overview of available data concerning molecular structures and biological activities of humic substances, with special emphasis on their hormone-like activities is given.
Journal ArticleDOI
Effect of low molecular size humic substances on nitrate uptake and expression of genes involved in nitrate transport in maize (Zea mays L.)
Silvia Quaggiotti,Benedetto Ruperti,Diego Pizzeghello,Ornella Francioso,Vitaliano Tugnoli,Serenella Nardi +5 more
TL;DR: The results show that the humic fraction with low molecular size used in this study is endowed with the characteristic structural network described for most humic substances so far isolated and confirm the presence of IAA in this fraction.
Journal ArticleDOI
High molecular size humic substances enhance phenylpropanoid metabolism in maize (Zea mays L.).
Michela Schiavon,Diego Pizzeghello,Adele Muscolo,Silvia Vaccaro,Ornella Francioso,Serenella Nardi +5 more
TL;DR: The results suggest that this humic fraction induces changes in phenyl Propanoid metabolism, the first study that shows a relationship between humic substances and the phenylpropanoid pathway.
Journal ArticleDOI
Capsicum chinensis L. growth and nutraceutical properties are enhanced by biostimulants in a long-term period: chemical and metabolomic approaches.
Andrea Ertani,Diego Pizzeghello,Ornella Francioso,Paolo Sambo,Santiago Sánchez-Cortés,Serenella Nardi +5 more
TL;DR: Two biostimulants, one derived from alfalfa plants (AH) and the other obtained from red grape (RG), were chemically characterized using enzyme linked immuno-sorbent assays, Fourier transform infrared (FT-IR) and Raman spectroscopies and suggested that AH and RG promoted plant growth and the production of secondary metabolites, such as phenols.
Journal ArticleDOI
Recent Applications Of Vibrational Mid-Infrared (Ir) Spectroscopy For Studying Soil Components: A Review
TL;DR: In this paper, the authors highlight the recent applications of mid-infrared spectroscopy and in particular of diffuse reflectance spectrograms (DRIFT) and attenuated total reflectance (ATR) and processing methods (e.g., deconvolution, derivative and chemometrics) to rapidly provide valuable information on soil composition and organic geochemistry.
