PROCESS FOR INCREASING THE LEVEL OF POLYAMINES IN CULTIVATED PLANTS AND PROCESS FOR SELECTING THE BACTERIA USEFUL IN THE PROCESS FOR INCREASING THE LEVEL OF POLYAMINES IN PLANTS

摘要

The invention relates to a process for increasing the level of polyamines in cultivated plants concomitantly with the reduction of the phytosanitary risk associated to necrophilic phytopathogenic agents. The process consists in cultivating a protective leguminous plant, during winter, and transforming said green crop into bioactive mulch by herbiciding and treating with bacteria antagonistic to necrophilic phytopathogenic agents, resistant to the total amount of used herbicides and exhibiting a capacity of releasing polyamines and precursors thereof from the vegetable material, seeding and growing the crops in the bioactive mulch.
