Supplementary Light Source Affects Growth, Metabolism, and Physiology of Adenophora triphylla (Thunb.) A.DC. Seedlings.

ABSTRACT: Adenophora triphylla (Thunb.) A.DC., a well-known herbaceous medicinal species, has been reported to protect against human obesity, cancer, and inflammation. Supplementary lighting is a practical strategy to improve crop quality, especially at a propagation stage. However, there has been no study available on the optimal supplementary light source for the commercial production of A. triphylla seedlings. In this study, plug seedlings were cultivated in a greenhouse for four weeks under an average daily light intensity of 490 μmol·m^-2·s^-1 PPFD coming from the sun and a supplemental lighting (16 h per day) at 120 μmol·m^-2·s^-1 PPFD provided by high pressure sodium (HPS), metal halide (MH), far-red (FR) light, white LED (re
