Abstract
Matricaria chamomilla L. plants were grown at various light intensities, under controlled conditions in the phytotron.
The reduction of light intensity resulted in a decrease in the number and dry weight of flower heads per individual plant, as well as, the size of single flower head. The decrease was relatively greater with decreasing light intensity up to 32000 ergs/cm2/sec.
It is conceivable that in general, the higher the light intensity, the higher the essential oil and chamazulene percentage.
The total amount of essental oil and chamazulene per individual plant increased with increasing the light intensity.
