Finally, the described responses in the photosynthetic performance were strongly affected by the degradation of photosynthetic pigments, aprocess which was more evidentin plants grow neither under 100molm−2 s−1 or 30%of blue light (Tables 1and2). UV radiation generates freer adicals that cause damage to the photosynthetic machinery and lead to degradations of Chl a + b and carotenoids (Hideg etal.,2013). The stronger the degradation of those pigments, the higher will be the thermal dissipation as this
