2. Introduction
• Lycopene  prevention of cancer, cardiovascular disorder, etc.
(Kong et al., 2010)
• β-carotene  provitamin A & natural pigment.
• Prospective high economic value

3. (Pizarro & Stange, 2009)
(Kondo et al., 2014)

4. Aims of Study
• To determine the optimal light spectrum to enhance
lycopene, β-carotene and sugar production in cherry tomato
fruits.
• To construct mass distribution of lycopene, β-carotene and
sugar production in plant treated with red, white and blue
light exposure.

11. Conclusion
•Red light (663 nm) treatment enhanced lycopene, β-carotene and
sugar 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 treated
with white light, while the highest yield of fruit (1.15 fold), sugar,
lycopene and β-carotene were observed on plants treated with red
light.
