ABSTRACT. Transition to organic farming
requires the development of new methods to protect seeds from adverse factors.
The germinative process and the post-germinative phase are strictly controlled
by the oxidative balance involving lipid peroxidation, reactive oxygen species
and enzymes activity, directing the plant viability and its further
development. We focus our studies mainly on the seeds protection and
fortification through natural solutions based on marigold and fenugreek
extracts, steroid alkaloids from tomatoes and hydrolyzed proteins derived from
leather waste industry. The structural configuration of the plant protection
products proves significant effects fighting on different mechanisms of seeds’
oxidative stress. As well as the experimental design highlighted a tandem
correlative mechanism between germination, decrease of lipid peroxidase and
activation of catalase and superoxide-dismutase. SEM-PROTECT II was the most
active biopesticide involved in these processes. Our findings directed
complex research oriented to technological and experimental optimizations for
the development of an innovative, efficient and competitive plant protection
product to meet modern agriculture requirement.
