However, the carotenoid content
was quite stable under both conditions.
According to the photoprotective role of
carotenoids, their content was expected to
increase under the high light condition.(11)
The stable carotenoid content in croton
leaves in high light intensity conditions
suggested that the conditions used in this
experiment were not so stressful that the
plants had to adjust themselves by
increasing the carotenoid content. Only
the reduction of the antenna complex size
by decreasing the chlorophyll content was
enough for plant survival in such
conditions.
