[The fine structure of chromoplasts from plasmochromous perigon-leaves of Tulipa]. / Die Feinstruktur der Chromoplasten in plasmochromen Perigon-Blättern von Tulipa.

ABSTRACT

The chromoplasts of yellow perigon leaves of Tulipa derive from the young chloroplasts present in the bud stage. During chromoplast development and thylakoid breakdown many large plastoglobuli (diameter 80-360 nm) are formed. The function of the petal plastoglobuli as stores for the chromoplast lipids such as plastidquinones and carotenoids is discussed.
