Notes:
The relationship between optical measurements of whole tomato and pigment content was studied. The difference between the absorbances (A) at 710 and 780 nm [ΔA (710–780 nm)] correlated significantly (r = 0.98) with chlorophyll contents of 0.3–13.4 μg/g fresh weight (gfw). The ΔA (570–780 nm) correlated significantly (r = 0.97) with lycopene contents of 0.2–46.7 μg/gfw. The ΔA (550–580 nm) correlated significantly with the β-carotene, content (r = 0.95). The reflectance measurements correlated with the chlorophyll and lycopene contents, but the coefficients were lower and the standard errors were larger than those observed with the absorbance measurements.
