Conteúdo: 	Re-greening of valencia sweet orange (Citrus sinensis (L.) Osbeck) results from an increase in plastid  lamellae in the two outer cellular layers of the rind, corresponding with a decrease in carotenoids and starch content. Plastids containing lamellae without any grana stacks are dominant in re-greening fruit. Green fruit contained normal chloroplasts, even in epidermal cells, and plastids with high proportions of lamellae were evenly distributed between the outer and inner two layers of cells. Re-greened fruit contained twice as many plastids in the outer layers with lamellae  less than 25% that of the green fruit. Ethephon decreased chlorophyll and increased starch contents in the plastids, suggesting that changes in the starch conten of the cells are related to lamellae development.
