The Effect of Various Wavelengths of LED Light on the Physiological and Morphological Parameters of Comfrey (Symphytum officinale L.)
Öz: The aim of this study was to examine the effect of five different wavelengths of light on the comfreyplant (Symphytum officinale) (family Boraginaceae). The light source and wavelengths used in thestudy were UV-A (390-410 nm), blue (465-485 nm), red (620-630 nm) and cool white (CW) daylight(400-700 nm, 6500 K), LED (Light Emitting Diode). In the study, each of the 5 different lightapplications was applied for 45 days (T1: 100% blue; T2: 100% red; T3: 60% blue + 35% red + 5%UV-A; T4: 100% CW daylight; T5: 80% CW + 20% red). The experiments were carried out underconditions of 22C temperature, 60% humidity, 16/8 hours light/dark and 180 µmol.m-2.s-1Photosynthetically Active Radiation (PAR). After each application, measurements were taken ofnumber of leaves, number of roots, height of plant, amount of chlorophyll in leaves, leaf colour andbrightness. According to data obtained, the different wavelengths of the coloured light applied in thegrowing environment created a change in colour and brightness of the leaves, height of the plant,length of the roots, and number of leaves and roots.
