Abstract Populus trinervis is native to China and plays an irreplaceable role in maintaining the ecological balance of boreal and temperate forests. P. trinervis mainly grows in high-altitude areas. At present, there are limited studies on the response of P. trinervis to different light qualities, so it is necessary to investigate the photosynthetic physiological changes of P. trinervis in different light environments. In our study, P. trinervis was grown for 8 months under light filtered by three different colored films. The three treatments were blue film, green film, and white plastic film. The effects of blue (B), green (G), and white… More >

Abstract Michelia macclurei Dandy is a significant tree species that has extensive cultivation for forestry and horticulture purposes in southern China, owing to its economic and practical importance. Light quality influences plantlet growth and development during tissue culture. However, the growth characteristic and molecular regulation of M. macclurei under different light quality conditions are not well understood yet. In this study, we investigated the morphological, chlorophyll content, and transcriptomic responses of M. macclurei plantlets under different light-emitting diode (LED) qualities, including white, blue, and red light. The results showed that blue light significantly increased plant height (21.29%) and leaf… More >
