Red LED light accelerates capsanthin accumulation and fruit ripening in pre-harvest pepper (<i>Capsicum annuum</i> L.).

ABSTRACT: As an essential environmental regulator, light plays a crucial role in pre-harvest fruit quality and fruit ripening. However, developing efficient light-based strategies for precise regulation during critical crop growth stages remains a substantial challenge in controlled-environment agriculture. Fruit ripening in pepper (Capsicum annuum L.) is characterized by the development of its distinctive red color, which is primarily driven by the accumulation of capsanthin, a carotenoid that serves as the principal pigment in ripe pepper fruits. Nevertheless, the mechanism by which red LED light regulates capsanthin accumulation, and thus the color change of pepper fruits, remains unclear. In this study, 'Zunla-1' pepper fruits at the green ripening stage (30 days after flowering, DAF) wer
