Reakcja siewek pszenżyta ozimego na zróżnicowane natężenie oświetlenia i podwyższone stężenie CO2

Abstract

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.
