EFFECT OF SIX DIFFERENT LED LIGHT QUALITIES ON THE SEEDLING GROWTH OF PAPHIOPEDILUM ORCHID IN VITRO
In this study, we investigated the effects of six different LED light qualities on the growth of Paphiopedilum seedlings in vitro. The CW treatment had the highest value on shoot fresh weight, whereas the 8R1G1B treatment had the highest shoot dry weight. The seedlings grown under the B treatment were the most compact, showing the shortest leaf length and width. For root growth, the highest value on fresh weight was found under the B treatment, and the highest dry weight was found under the B and R treatments. The optimum growth of Paphiopedilum seedlings was found under CW and 8R1G1B treatments. The higher Fv/Fm and yield values also reflected the vigorous growth of these two treatments.
