Structural and functional Changes in Chloroplasts of senescent Leaves of Sophora japonica L.
Mercedes Wrischer

Sažetak
The leaves of Sophora japónica remain green throughout the autumn then fall off late in November or the beginning of December without change in their colour. Their ultrastructure, pigment content and photosynthetic activity were investigated in two week intervals from mid September till the beginning of December. The ultrastructure of the chloroplast was quite normal during this time. The gradual increase of plastoglobules and the presence of some interthylakoidal inclusions showed that senescence was still in progress. The content of pigments and the photosynthetic activity of the leaves were also normal. The enhanced senescence did not start until late autumn in leaves which had already fallen off the trees.
