for red grapes (CIRG), colorimetric values were calculated using the CIRG = 180-hue * / (L * + C *)equation, where C * is calculated with C * = a* 2 + b * 2) 1/2 and hue * is the angle calculated with hue * = tan[g.sup.-1] (b * / a *) (CARRENO et al., 1995).
Pearson correlation test was used to analyze the correlation between lycopene, HMF, and color index
M52's yellow-orange star is a foreground giant with a spectral class of F8, implying a color index
of 0.56, which goes hand-in-hand with a yellow-white star.
At 21, 32 and 41 days after transplanting, at which time the advanced symptoms of nutritional deficiency were expressed, tiller and leaf counts, shoot height and determination of the green color index
Thermal Alteration Index ( TIA) and Spore Color Index
(SCI) suggest that lower part is oil prone, middle part is gas prone and upper part is immature.
Since the green component of the digital image (G) alone, which ranges from 0 to 255, does not define the color green, the green color hue (H) was also determined in degrees (where 60[degrees] is yellow and 120[degrees] is green) along with the Dark Green Color Index
(DGCI), which ranges from 0 to 1.
The color index
of around 1, the viscosity index of over 90, and the pour point of below minus 6 degrees Celsius are the key specifications of the new product, which has been highly appreciated on the target markets.
The content of pectic substances in culture liquids was determined by color index
by measurement of optical density using a KFK-2 photocolorimeter at a wave length of 315 nm.
The L*, a*, and b* values were used to calculate Hue, Chroma, and the Total Color Index
using the following formulas:
Other practices like geo-referenced site specific crop management may include; electromagnetic soil mapping, soil sample collection, crop yield data collection, aerial imagery, crop or soil color index
maps, soil types and characteristic, drainage level and potential yields.
