| Abstract |
In controlled environment crop production, light is one of the most important limited factors for plant growth. Light emitting diodes (LED) usually provide specific quality, quantity of light and high intensity source of visible radiation for better growing commercial horticultural plant production. The objective of this study was to examine growth and development of Jerusalem artichoke (Helianthus tuberosus L; JA) which was grown in controlled lighting conditions under different light source treatment i.e. natural light (NL) as a control, Red light LEDs (R), Blue light LEDs (B) and Red + blue LEDs (R+B), respectively. The result showed that the relative growth rate was lowest under B light. The net assimilation rate and SPAD value were higher under R, B and R+B lighting when compare with NL. The higher photosynthetic pigments were found in leaves of JA under R lighting. This condition was seemly increased greater chlorophyll a and chlorophyll b than other light treatment. The higher carotenoids were found in JA under R, B and R+B lighting treatment. JA grown under R, B and R+B lighting were suitable for new tuber growth, as bigger size and higher fresh and dry weight. Our findings demonstrate that LEDs light could enhance Jerusalem artichoke tuber yields and qualities in controlled conditions. |
