Growth Regulator Activity of Macro-Sorb® Foliar in Vitro

October 2005
Scientific articles | Terra-Sorb®

In vitro growth responses elicited by separated fractions of Macro-Sorb Foliar© (FOLIAR), a common biostimulant applied to golf course turfgrasses, were investigated using two bioassays specific and sensitive to auxin or cytokinin. Auxin responses were tested using the Avena (oat) first internode straight growth bioassay using increasing concentrations of indole-3-acetic acid as an internal standard. Cytokinin responses were tested using the Raphanus (radish) cotyledon expansion bioassay, w...

Amino Acids as Elicitors: a Way to Increase Plant Stress-Tolerance

May 2005
Scientific articles | Terra-Sorb®

Several amino-acids are currently used in U.S. horticulture: gibberelic acids, auxines, cytokinins, etc. , mostly as inhibitors. In the last decade, amino acids biostimulants use increased because of their ability to improve the overall plant’s health, including better stress tolerance, reports Gordon Kauffman. The validity of these biostimulants as a positive growth regulator/stress tolerance enhancer has been primarily based on testimonials.

Stress Proteins in Plants

May 2004
Scientific articles | Others

Unfavourable climate conditions, pathogen attacks and certain states of plant development trigger the expression of so-called stress proteins. From the moment the plant receives the stimulation signal until it synthesizes the stress-response proteins, several different processes take place: recognition of the stress factor, synthesis of secondary metabolites that act as transduction signals, expression of the genes and, finally, synthesis of the different stress proteins

Control of Some Pathogens by Using Special Foliar Fertilizers

November 2003
Scientific articles | Terra-Sorb®

The present work points out to the interdisciplinary experimental results, obtained in the experimental fields of the Plant Protection and Soil Science Department, as well as at data which stress upon the interdependency between the satisfaction of the trophically needs of the wheat plants and the aggressiveness of the pathogens which cause the disease.The experimental results underline the fact that the attack level expressed through intensity and attack degree is different, both with the ...
