Humic substances isolated from residues of sugar cane industry as root growth promoter
Plant growth promoting substances are widely used in modern agriculture. Several products in the market are humic substances isolated from different sources. The filter cake, a residue of sugar production, is a rich and renewable source of organic matter and these characteristics place the filter cake as a possible source of plant growth promoting substances. Humic acids (HA) from filter cake w...
متن کاملPhysiological responses of peppermint (Mentha piperita L.) to plant growth regulators and salinity stress
Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...
متن کاملPhysiological effects of humic substances on higher plants
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 on the source, concentration and molecular weight humic fraction. While a low molecular size (LMS , 3500 Da) fraction easily reaches the plasmalemma of higher plant cells and, in part, is taken up into them, ...

متن کاملBinding of mercury(II) to aquatic humic substances: influence of pH and source of humic substances.
Conditional distribution coefficients (K(DOM')) for Hg(II) binding to seven dissolved organic matter (DOM) isolates were measured at environmentally relevant ratios of Hg(II) to DOM. The results show that K(DOM') values for different types of samples (humic acids, fulvic acids, hydrophobic acids) isolated from diverse aquatic environments were all within 1 order of magnitude (10(22.5 +/-1.0)-10...
