Physiological effects of humic substances on higher plants
Abstract The physiological effects of humic substances (HS) on some aspects of plant growth and metabolism are examined. Evidence has been presented on that the effect of HS on plant growth depends…
Humic substances biological activity at the plant-soil interface
TLDR
An overview of available data concerning molecular structures and biological activities of humic substances, with special emphasis on their hormone-like activities is given.
Effect of low molecular size humic substances on nitrate uptake and expression of genes involved in nitrate transport in maize (Zea mays L.).
TLDR
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.
Biostimulant activity of two protein hydrolyzates in the growth and nitrogen metabolism of maize seedlings.
TLDR
Two protein hydrolyzate–based fertilizers, one from alfalfa and one from meat flour, were studied chemically and biologically and a role of amino acids and small peptides of the two PHFs is suggested in the regulation of the hormone-like activity and nitrogen pathway.
Earthworm humic matter produces auxin-like effects on Daucus carota cell growth and nitrate metabolism
TLDR
It is shown that HEf affects nitrate metabolism, has auxin-like activity, was strongly acidic and had elevated peptide, carbohydrate and aliphatic C contents.
Alfalfa plant-derived biostimulant stimulate short-term growth of salt stressed Zea mays L. plants
TLDR
It is proved that the EM increases plant biomass even when plants are grown under salinity conditions, likely because EM stimulated plant nitrogen metabolism and antioxidant systems.
Effects of an alfalfa protein hydrolysate on the gene expression and activity of enzymes of the tricarboxylic acid (TCA) cycle and nitrogen metabolism in Zea mays L.
TLDR
The results suggest that EM might promote nitrogen assimilation in plants through a coordinate regulation of C and N metabolic pathways and open the way for further research on protein hydrolysates as a valid tool to improve N use efficiency and, as a consequence, to reduce the intensive use of inorganic N fertilizers in agriculture.
Effect of commercial lignosulfonate-humate on Zea mays L. metabolism.
TLDR
In light of these results, being environmentally friendly products, lignosulfonate-humate a and ligno-substance-based products could be used to increase crop yield.
Biological Activities of Humic Substances
Protein hydrolysates as biostimulants in horticulture
TLDR
An overview of the biostimulant properties of PHs on productivity and product quality of horticultural crops, in particular fruit trees, vegetables, flower crops and ornamentals is given.
