Introduction
• Lycopene prevention of cancer, cardiovascular disorder, etc.(Kong et al., 2010)
• β-carotene provitamin A & natural pigment.
• Prospective high economic value
(Pizarro & Stange, 2009)
(Kondo et al., 2014)
Aims of Study
• To determine the optimal light spectrum to enhancelycopene, β-carotene and sugar production in cherry tomatofruits.
• To construct mass distribution of lycopene, β-carotene andsugar production in plant treated with red, white and bluelight exposure.

Conclusion
•Red light (663 nm) treatment enhanced lycopene, β-carotene andsugar production in cherry tomato fruits, with increment of 35.8%,46.5%, and 27.5% respectively.
•The best vegetative growth was observed on tomato plants treatedwith white light, while the highest yield of fruit (1.15 fold), sugar,lycopene and β-carotene were observed on plants treated with redlight.
