All Parts of the Chrysanthemum are Shinning

November 5, 2005, after an academic exchange, we found that the Chrysanthemum on the balcony had blossomed out gradually and many had been in full bloom. The flowers were beautiful and vigorous. These Chrysanthemums were in bud when moved from the garden 3 or 4 hours ago. We thought maybe it¡¯s too quick. So we immediately went to the garden, where we found the Chrysanthemum just blossomed out a little, seldom were in full bloom.
We took the photos of the chrysanthemums on the balcony. To our surprise, we found that nearly every part of the chrysanthemums was shining brilliantly.

Sample photos
The shining part
The full-blown chrysanthemum
The whole flowers are clouded by the red light, and the right next to the flower is a thin layer of purple light.

The under-blooming chrysanthemum
The whole flower is shining. From the inner to the outer: the inner is a thin layer of yellow light or purple light somewhere; the outer layer is clouded by the thick red light.
Chrysanthemum still in mud

The whole Chrysanthemum is shining. The inner layer on the top of the flower is the thick yellow light, but the inner layer of the stem is the thin purple light, and the outer layer of the flower is clouded by the red light.

Why does the chrysanthemum shine? Why the irradiancy of each part is different? Does the light have an effect on the plant growing? Of course, the most important questions are: what¡¯s the light? And where does it come from?
