Biometric measurement and index of greenness of winter triticale seedlings cv. Prado
were made after 14 days of growth in controlled conditions. Two levels of photosynthetic photon
flux density (PPFD): 400 i 800 Dmol · m–2 · s–1 were set as well as four levels of CO2 concentration:
400 (control), 800, 1200, 1600 Dmol · mol–1. Stimulating effect of higher lever of CO2 concentration
on seedlings has been established (to control). Favorable impact of lighting intensity (PPFD)
800 Dmol · m–2 · s–1 and concentration of CO2 800 Dmol · mol–1 on biometric features of analyzed
seedlings has been shown.
