Abstract

The main objectives of this research are to study color image analysis for determining the optimal harvest time of green beans (Phaseolus vulgaris L. var Paulista) and green peas (Pisum Sativum L. var Sugar Lays) depending on maturity, and creating the color standards at different ages. Obtained results are summarized as follows: 1) The percentages of color components increased for read (R), green (G) and blue (B) from 29.0% to 60.4%, from 44.3% to 76.5%, and from 15.3% to 49.0% for pod ages from 10 to 31 days, respectively. Meanwhile, the values for sweet pea pods increased from 26.67% to 51.76%, from 41.18% to 61.57%, and from 15.29% to 29.80% for pod ages from 6 to 33 days, respectively.  2) The relationships between red color (R), green color (G) and blue color (B) as functions of the pod age (A) resulted as follows: R = 39.490 + 3.909A, G = 78.203 + 3.755 A, and B = 3.826 A - 1.063    (green bean pods) R = 52.767 + 2.423A, G = 96.462 + 1.817 A, and B = 34.027 + 1.080 A   (sweet peas pods) 3) According to this study, the criteria as a standard for quality depending on the color to determine the optimal harvest time  appeared about 22 and18 days for green bean and pea pods (from appearing the pod from its flower) were 34.12% (R),   43.04%(G) and 22.83% (B) for bean, while they were 33.45% (R), 45.99% (G) and 20.56%(B)for peas.
