“at a low temperature, the values of effective quantum yield of photosystem II photochemistry (Φ PSII ), net photosynthetic rate ( P n ), stomatal conductance ( g S ), and transpiration rate ( T r ) —as well as those of N, K, and P uptake—were the highest at 350 μmol·m −2 ·s −1”

“followed by 500 μmol·m −2 ·s −1 , which resulted in higher values for leaf number (LN), leaf area (LA), dry weight (DW), and fresh weight (FW)”
“sunflower (Helianthus annuus L.) plants were grown for 50 days under two photon flux density (PFD) conditions, namely high irradiance (HI) at 350 μmol(photon) m-2 s-1 and low irradiance (LI) at 125 μmol(photon) m-2 s-1”

“Nitrate reductase (NR) activity decreased with leaf ageing in both treatments. However, the NR activation state was higher during early leaf development and decreased more markedly in senescent leaves in plants grown under HI. GS activity also decreased during sunflower leaf ageing under both PFD conditions, but HI plants showed higher GS activities than LI plants.”

“Glucose contents were higher in HI plants than in LI plants; the differences were statistically significant (p<0.05) mainly at the beginning of the leaf senescence. On the other hand, starch contents were higher in HI plants than in LI plants, throughout the whole leaf development period.”

“Heavy (H) and light (L) fall (F) grazing intensities caused lower ( P < 0.05) grain yields compared to controls (C) in 1983 to 1984 (2.94[F‐L] and 2.53 [F‐H] vs. 3.51 [C] Mg ha −1 )”

“The plants grown under HI exhibited considerable oxidative stress in vivo during the leaf senescence, as revealed by the substantial H2O2 accumulation and the sharply decrease in the antioxidant enzymes, catalase and ascorbate peroxidase, in comparison with LI plants. Probably, systemic signals triggered by a high PFD caused early senescence and diminished oxidative protection in primary leaves of sunflower plants as…” Show full quote
