摘要：

Tristimulus colorimetry and chlorophyll concentration were used to quantify the color of 34 green-seeded dry pea cultivars grown at two locations in southern Manitoba in 1990 and 1991. The tristimulus color data, expressed as L, a and b, of ground seed were significantly correlated with contents of chlorophyll a and b and total chlorophyll. The hue function tan-1 b/a was highly correlated with chlorophyll a/b, total chlorophyll and contents of chlorophyll a and b. For whole pea seed, however, tristimulus color values were found to be poorly correlated with chlorophyll content. Tristimulus color evaluation of three green-seeded pea cultivars stored at 10, 25 and 40C and 11, 33, 52 and 75% relative humidity for up to 45 days revealed no significant loss of green color except in samples stored at 40C and 75% relative humidity, which displayed less green and more yellow color.
