Abstract

Abstract

En 中文
• Irradiated plants show higher photosynthesis despite lower pigment content. • Low UV doses trigger beneficial hormetic acclimation and antioxidant defense. • Progressive UVR8 expression suggests a role in perceiving UV-C radiation. • Pre-flowering UV radiation boosts tomato size, fruit yield and flower production. • UV treatment increases lycopene by 31% and carotenoids by 27% in fruits.
