摘要
The aim of this study was to investigate the response of in vitro cultivated highbush blueberry (Vaccinium corymbosum 'Bluecrop') to lighting from different light-emitting diodes (LEDs). The plantlets were cultivated in vitro under an illumination system based on Philips GreenPower LED research module. Four groups of LEDs emitting in white (W), red (R), blue (B), mixed (W:R:B:far-red = 1:1: 1:1) were studied. Growth parameters, content of photosynthetic pigments and chlorophyll a fluorescence of the plants grown under different LED light were measured. LED lighting affects plant growth, morphogenesis and pigments content of highbush blueberry in vitro. The best results with highest fresh and dry weight, multiplication index and number of leaves were obtained under mixed LEDs.
