Formulations comprising indole and/or indole derivatives for increasing the capacity of plants to assimilate mineral nutrients.

摘要

The object of the present invention is a formulation with the potential to increase the efficiency of a plant's assimilation of nutrients both in normal conditions and in conditions of nutrient deficiency. It is especially effective in the case of iron assimilation in conditions of deficiency of this micronutrient, by improving and potentiating a plant's specific response to iron deficiency, increasing the plants capacity to mobilize and assimilate the iron present in non-assimilable forms. The formulation is characterized in that is contains a compound of the formula where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 can be hydrogen, an alkyl, aryl or phenyl residue.
