Rhodothamnus sessilifolius is a species of the Ericaceae family endemic to the Artvin province in NE Turkey. This is in the critically endangered species list and current populations are decreasing, therefore, it requires protection and reproduction. Thus the present study aimed to investigate the effect of various gibberellic acid (GA3) applications on germination of the R. sessilifolius seeds. The effects of various GA3 concentrations on final germination percentage, mean germination time, germination value, and germination rate were analyzed in a growth cabinet. The study demonstrated that gibberellic acid application positively affected germination. Seed percentages of germination were 2.22 %, 18.89 %, 17.78 %, and 15.56 % in the control group for 100, 500 and 1000 ppm GA3 concentrations, respectively. First germination was observed in seeds treated with GA3 after 11 days. There were significant differences (P < 0.05) between all measured germination properties. These results are promising for future conservation strategies.

Rhodothamnus sessilifolius es una Ericaceae endémica de la provincia de Artvin en el noreste de Turquía. Esta especie se encuentra en la lista de especies en grave peligro de extinción y la población actual continúa disminuyendo, por lo tanto, requiere protección y reproducción. El presente estudio tuvo como objetivo investigar el efecto de varias aplicaciones de ácido giberélico (GA3) sobre la germinación de las semillas de Rhodothamnus sessilifolius. En cabina de crecimiento se analizaron los efectos de varias concentraciones de GA3 sobre el porcentaje de germinación final, el tiempo medio de germinación, el valor de germinación y la tasa de germinación. El estudio demostró que la aplicación de ácido giberélico afectó positivamente la germinación. Los porcentajes de germinación de la semilla fueron de 2,22 %, 18,89 %, 17,78 % y 15,56 % para el grupo de control y para concentraciones de 100, 500 y 1000 ppm de GA3, respectivamente. La primera germinación se observó en semillas tratadas con GA3 después de once días. Hubo diferencias significativas (P < 0,05) entre todas las propiedades de germinación medidas. Estos resultados son prometedores para futuras estrategias de conservación.
