Sažetak
The effect of isopropyl N-phenylcarbamate (IPC) on the process of transformation of chloroplasts into chromoplasts in the petals of Forsythia suspensa flowers has been studied by the application of light and electron microscopy and pigment analysis.
In treated petals only about 30°/o of plastids have been transformed into chromoplasts. They contain tubules, “vacuole-like” inclusions and plastoglobules but very -rarely in their typical form. A great number of plastids (70°/o) has not been transformed and preserved the structure of chloroplasts until the withering of the flowers.
The pigment analysis has shown that IPC has inhibited the disappearance of chlorophyll and retarded the synthesis of carotenoids duing the process of flower development.
