Abstract
Sunt prezentate şi analizate unele realizări din ultimele decenii referitoare la utilizarea de către mai mulţi autori a macroalgelor marine în calitate de surse producătoare de biostimulatori pentru sporirea creşterii plantelor de cultură şi majorarea rezistenţei lor la secetă şi la alţi factori abiotici. Cianobacteriile, de rând cu algele marine şi microalgele, prezintă un interes sporit din punct de vedere aplicativ, datorită componenţei biochimice valoroase, precum şi capacităţii de producere a unor metaboliţi, inclusiv fitohormoni, aminoacizi, exopolizaharide etc. În lucrare este prezentat un studiu de caz cu evaluarea efectului unor biostimulatori naturali, elaboraţi în baza filtratelor, rezultat de la cultivarea cianobacteriilor Spirulina platensis şi Calothrix marchica asupra germinării seminţelor şi creşterii plantulelor plantei aromatice Menta spicata L. în primele 15 zile după germinare.
Some achievements from the last decades regarding the use of marine macroalgae by numerous authors as sources of biostimulants producers to increase the growth of crop plants and their resistance to drought and other abiotic factors are presented and analysed. Cyanobacteria, next to seaweed and microalgae, are of increased interest for applied agriculture due to their valuable biochemical composition, as well as the ability to produce metabolites, including phytohormones, amino acids, exopolysaccharides, etc. A case study is presented assessing the effect of natural biostimulants, based on filtrates resulting from the cultivation of cyanobacteria Spirulina platensis and Calothrix marchica on the seeds germination and growth of aromatic plant Menta spicata L. seedlings in the first 15 days after germination
