Sažetak
The quality and quantity of light are important factors for the production of quality seedlings of vegetables. Effective portion of the spectrum for photosynthesis is in the red and blue light, however, in the production of seedlings additional LED lighting that emits light just in the range of those wavelengths are often used. The aim of this study was to determine the effect of red, blue and combinations of red and blue LED lights and fluorescent lights on morphological characteristics, SPAD index and the content of chlorophyll, carotenoids and phenol in the leaves of pepper (Capsicum annuum L.) in two terms of measurements during the growth. The highest content of chlorophyll, carotenoids, SPAD index and the largest leaf area was established in the treatment red + blue LED illumination. The lowest values of the width and length of the leaves were found in plants grown under red LED light while the lowest total plant height determined in plants grown under fluorescent lights. From these results we conclude that additional LED lighting using a combination of light from the blue and red parts of the spectrum can positively affect the growth and development of seedlings of pepper. Further research is needed to determine the most favourable ratio of before mentioned wavelengths of the spectrum through the stages of growth and development as well as for individual varieties, because numerous studies confirm different response of certain varieties in the same plant species.
