Structural and Functional Changes of Plastids during yellowing and regreening of Lemon Fruits

Abstract
Photosynthetic activity, pigment content and fine structure of plastids in the rind of the lemon fruits have been studied. Lemon fruits very regularly change their colour through seasons — from green into yellow and into green again.
Photosynthetic activity has been detected only in young green and regreened fruits. In yellow fruits, although they contained small amounts of chlorophylls, phyotosynthetic activity was unmeasurable. The electron microscopic examination has shown that the changing of colour of fruits is the result of a typical transformation of chloroplasts into globular chromoplasts and vice versa.
