Abstract: The present invention relates to the use of a fructooligosaccharide (FOS) comprising from 2 to 10 monosaccharide units, as an elicitor of the mechanisms of absorption of mineral elements from the soil, and of the defense mechanisms against pathogens. It also relates to a fertilizing and biostimulating composition containing these fructooligosaccharides, and to the use thereof in a method for treating crop plants.

Abstract: This invention relates to a new formulation activating the absorption of mineral nutrients by plants. Consequently, it has also an effect on the metabolization of these mineral compounds by the plant. These formulations that have been discovered with this property activating nutrient absorption have as main component the compounds represented by general formula 1 CH3—S—CH2—CH2—CH(OR1)—COR2??1 where R1 is selected from the group formed by hydrogen, alkyl rests, (preferably methyl or ethyl), and aryl: while R2 is selected from the group formed by hydroxyl, amides, alkyl rest esters (preferably methyl or ethyl), or aryl. When the rest is hydroxyl, acid salts with monovalent cations, preferably Na+ and K+, polyvalent cations, preferably Cu++ and Fe+++, and electropositive organic compounds such as amines (e.g., ethanolamine) are also considered.

Abstract: A new use of 2-hydroxy-4-methylthiobutanoic acid (HMTB) as an inducer, within the plant, of ethylene and polyamine synthesis, mainly putrescine, capable of regulating fruit maturation processes, both in relation to fruit abscission and in relation to color and sugar content, containing mineral elements such as phosphorous, potassium and nitrogen.
