Accumulation of pigments and fragmentation characteristics of mesophyll and bundle-sheath chloroplasts of maize

, : Accumulation of pigments and fragmentation characteristics of mesophyll and bundle-sheath chloroplasts of maize. Photosynthesis, two centuries after its discovery by Joseph Priestley Proceedings of the 2nd International Congress on Photosynthesis Research, Stresa, Italy, June 24-29, 1971: 1481-1484

The chlorophyll and carotenoid contents of individual (a) mesophyll and (b) bundle-sheath chloroplasts of maize were compared at different stages of greening. Increase in chlorophyll content during greening was similar in both types of chloroplast. At the beginning of greening, carotenoid content/chloroplast was higher in (b) than in (a). In fully developed chloroplasts chlorophyll-a:-b ratio was higher in (a) than in (b).
