| Abstract:
This study was conducted to investigate the effect of light quality on the growth of potato (Solanum tuberosum L. var. Dejima) transplants and the tuber yield after transplanting of potato transplants. Potato transplants were grown under blue, red, blue+red, and white fluorescent lamps having photosynthetic photon flux of 200 µmol•m-2•s-1 and photoperiod of 16 h•d-1. Chlorophyll content and number of nodes of potato transplants were significantly higher than those grown under blue, red and white fluorescent lamps. Average number of tubers per plant after transplanting of potato transplants was 8.5 for blue+red, 7.4 for red, 6.7 for blue, and 6.2 for white light. Average weight of tubers per plant was 1,150 g for blue+red, 750 g for white, 580 g for blue, and 495 g for red light. It can be concluded that it is possible to produce the healthy transplants and to increase the yield of tubers after transplanting by the illumination of blue+red light at nursery stage of potato transplants | |
