Red light and biostimulants containing arbuscular mycorrhizal fungi enhance ajmalicine and serpentine production in Catharanthus roseus under indoor conditions.

ABSTRACT: Indoor farming offers optimal conditions for high and stable ajmalicine and serpentine yields in Catharanthus roseus, enabling precise control over environmental stimuli such as light and biostimulants. This study aimed to evaluate, for the first time, the combined effects of LED light spectrum and a biostimulant containing arbuscular mycorrhizal fungi on ajmalicine and serpentine production in indoor-grown C. roseus. Following a 60 days pre-treatment under white LEDs, plants received eight treatments: white (W, control), red (R), blue (B), red-blue (RB, R:B = 6:1) LED light, and their combinations with the biostimulant (BS). Samples were collected before treatments (T0) and at harvest (T1, 92 days after pre-treatment). R and RB significantly increased aerial fresh weight compared to W and
