Abstract

Chlorophyll concns decreased rapidly as pods matured from the 1-day-old fruit stage. Total
chlorophyll a + b per pod was influenced by pod length as well as pigment concn. Apparent chlorophyll
synthesis occurred in field-grown green snap bean fruits up to 11-mm diam pods (sieve size 5 or 6), but a
net decrease occurred with further maturation. Dry-mature persistent-green pods contained 300 ppm
chlorophyll on a dry matter basis, whereas normal-green pods had none. Lack of consistent agreement
between visual and chemical methods to rank cultivars for pod color suggested differences in chlorophyll
distribution in external versus internal tissue.
