  [Aroid-l] Philodendrons produce infrared light???

Dear All,

I have studied, with Denis Barab? et Roger Seymour, thermogenesis in many
aroids and particularly Philodendron.

The thermogenic process, the heating, is due to a particular respiration of
the cells of the spadix which converts the biological energy into heat.
Increasing the temperature of a body leads to increase its emission in the
infrared wave lengths (see picture on page 4 of the attached document).

In conclusion, yes thermogenic flowers/inflorescences can be detected in
infrared when heating. Heating is ten cause of the infrared radiations and
not the contrary.

About the pollination of Philodendron on the IAS web site you have several
pages dedicated to the pollination ecology of aroids and one particularly
on Philodendron :

I hope my explanations are clear.

All the best,
