STUDIEREA EFECTULUI BIOSTIMULATOR AL LICHIDULUI CULTURAL DE LA CULTIVAREA CIANOBACTERIEI SPIRULINA PLATENSIS ASUPRA GERMINĂRII SEMINȚELOR DE GALEGA ORIENTALIS LAM. MENȚINUTE ÎN COLECȚII

Abstract

In this study, the potential of biostimulants obtained from the culture medium of the cyanobacterium Spirulina platensis to improve the germination of Galega orientalis L. seeds maintained in collection conditions for 4 years was investigated. Throughout the experiments, the germination rate (GR) and germination index (GI) of seeds treated with different concentrations (1%, 2%, 4%) of the biostimulant were evaluated, compared to the control group. The results indicate a significant improvement in the germination of seeds treated with cyanobacterial biostimulants. The concentration of 2% biostimulant with a 2-hour exposure presented the highest germination rate over the analyzed period. These findings suggest that cyanobacterial biostimulants have potential in enhancing the germination efficiency of Galega orientalis L. seeds maintained in collection conditions for 4 years, offering promising applications in the efficient conservation of the species’ gene pool in seed collections and for agricultural practices aimed at improving crop performance.
