Adenophora liliifolia, also known as Lilyleaf ladybell or false campanula, has been influenced by human activity and its natural habitat has been affected. The populations of this species currently show a widespread decline throughout Europe and several national red lists and the Carpathian Endangered Species List classified it as threatened due to the impact of its habitats. This project focuses on the preservation of A. liliifolia germplasm, establishing an ex situ conservation protocol and the conservation of A. liliifolia through its ornamental use, which could preserve the species in the long term. The current study demonstrates that A. liliifolia can multiply and root on a synthetic Murashige and Skoog (MS) medium supplemented with different doses of growth regulator (PGR) and natural extracts, with good efficiency. According to the results, the appropriate culture medium for A. li...

El objetivo del trabajo fue evaluar el desarrollo del césped Bermuda (Cynodon dactylon) sobre diferentes sustratos, aislados del suelo por una manta de polietileno impermeable sola o combinada con malla raschel. Los sustratos, con espesor de 2 cm, fueron: S1 (100% compost), S2 (70% compost + 30% fibra de coco), S3 (50% compost + 50% fibra de coco), S4 (100% aserrín compostado), S5 (70% aserrín compostado + 30% compost) y S6 (50% aserrín compostado + 50% compost). Se evaluaron 12 tratamientos con tres repeticiones en un Diseño de Bloques Completos al Azar con arreglo factorial. Los resultados mostraron que el césped del sustrato S3 (50% compost + 50% fibra de coco) obtuvo el mayor porcentaje de cobertura, el mayor peso fresco foliar y la mejor calidad visual. Sin embargo, presentó un costo por metro cuadrado mayor al esperado, que podría ser reducido realizando ajustes en la canti...
