Abstract :The objective of the present study was to investigate the impact of light-emitting diodes insert ignore into journalissuearticles values(LEDs); on the morphological and developmental characteristics of wild cherry insert ignore into journalissuearticles values(Prunus avium); and common dogwood insert ignore into journalissuearticles values(Cornus sanguinea);. The LEDs used were L20AP67 insert ignore into journalissuearticles values(moderate blue, red and far-red, high green);, AP673L insert ignore into journalissuearticles values(moderate blue, high red);, G2 insert ignore into journalissuearticles values(low blue, high red and far-red);, AP67 insert ignore into journalissuearticles values(moderate blue, red and far-red);, and NS1 insert ignore into journalissuearticles values(high blue and green, low red, high red:far-red, 1% ultraviolet);. Fluorescent light [FL insert ignore into journalissuearticles values(high blue and green, low red);] tubes served as the control treatment. The growth rate and subsequently the shoot height of Cornus sanguinea were greater under FL. Root length of Prunus avium was longer under NS1. Prunus avium produced more biomass under NS1 and AP67, while Cornus sanguinea was favored under G2 and AP67. Greater root:shoot ratio was found under NS1 for Prunus avium and under NS1, AP67, G2, and AP673L for Cornus sanguinea. Root growth capacity insert ignore into journalissuearticles values(RGC); was also assessed in order to evaluate the transplanting response. RGC of Prunus avium and Cornus sanguinea was favored after precultivation under G2 and AP67, and under NS1 and AP67, respectively. Our study demonstrated that LEDs were more efficient in promoting a number of morphological characteristics than conventional FL in Prunus avium and Cornus sanguinea.
