dc.description.abstract The article starts with literature review on secondary metabolites, namely the iridoids contained in Linaria species (Scrophulariaceae). It describes the biological activity of the iridoid glycosides; the importance and the benefits of the secondary metabolites and their eventual application in organic plant cultivation. Is further elucidated the profile of the biologically active substances predominant in the purified extract of Linaria genistifolia (L.) Mill., named by us genistifoliosides. Are investigated the biological activity and the stimulating effect of genistifolioside aqueous solution in concentration 0.01% on the tomato seed germination, plants’ productivity (which is 33.9% higher) and the biochemical characteristics of the tomato fruit. It was elucidated, for the first time, the inhibitory effect of genistifolioside on the development of Alternaria alternata pathogenic fungi, affecting the vegetable crops; the 0.1% aqueous solution of genistifoliosides has the diameter of the fungi zone of inhibition 5.8 times bigger in comparison to the control sample and 4 times bigger in comparison to the certificated biopreparation. The purified extract of genistifoliosides exhibits properties of plant growth regulator as well as fungicidal properties and can be used in ecological agriculture. en_US
dc.description.abstract Aricolul începe cu o analiză bibliografică a metaboliţilor secundari, în special al iridoidelor, conţinuţi în speciile Linaria (Scrophulariaceae). Se relatează despre activitatea biologică a glicozidelor iridoidice, despre importanţa și beneficiile metaboliţilor secundari și eventuala aplicare a acestora în cultivarea organică a plantelor. În continuare este elucidate profilul substanţelor biologic active - glicozidelor iridoidice, predominante în extractul purificat de Linaria genistifolia (L.) Mill., denumite de noi genistifoliozide. Este investigată activitatea biologică și efectul stimulator al soluţiei apoase de 0.01% de genistifoliozide asupra germinării seminţelor de tomate, asupra productivităţii plantelor (care este cu 33.9% mai înaltă) și asupra indicilor biochimici ai tomatelor. Pentru prima dată a fost elucidate efectul inhibator genistifoliozidelor asupra dezvoltării fungilor patogeni Alternaria alternata, care afectează culturile lecumicole; soluţia apoasă de 0.1% de genistifoliozide ate diametrul zonei de inhibiţie a fungilor de 5.8 mai mare comparativ cu varianta martorului și de 4 ori mai mare comparativ cu biopreparatul certficat. Cercetările effectuate au demonstrat că extractul purificat de genistifoliozide manifestă atât proprietăţi de reglator de creștere al plantelor cât și proprietăţi fungicide și poate fi utilizat în agricultura ecologică. ro
