Fine Structure of Developing Chromoplasts in Outer Yellow Fruit Parts of Cucurbita pepo cv. pyriformis

Abstract
The changes in the yellow part of the fruit of Cucurbita pepo cv. pyriformis were followed by means of light and electron microscopy. In the earliest stages only proplastids have been found though the tissue appears thouroughly yellow. The proplastids develop into chromoplasts, which have a well developed clump of tubules and very few thylakoids. The chromoplasts of the ripe fruit contain a well developed system of specially perforated thylakoids which are connected in some places by means of characteristic bridge-like formations. The explanation of their structure in three dimensions is attempted. During the decay of the fruit the thylakoids disintegrate at first, and finally the structure of the whole chromoplast breaks down.
