The inflorescence of Philodendron selloum temporarily maintains a core temperature of 38� to 46�C, despite air temperatures ranging from 4� to 39�C, by means of a variable metabolic rate. The heat is produced primarily by small, sterile male flowers that are capable of consuming oxygen at rates approaching those of flying hummingbirds and sphinx moths.

Respiration of thermogenic inflorescences of Philodendron melinonii: natural pattern and responses to experimental temperatures.

It is concluded that the male floret tissues possess the same thermoregulatory mechanism of more precise thermoreGulatory species, but a combination of small spadix size, moderate thermogenic capacity, and slow reaction time result in poor thermoregian performance during the second day.

Pattern of respiration by intact inflorescences of the thermogenic arum lily Philodendron selloum

The data imply that the short peak phase is related to characterized by two episodes of heating—the first pro- the enhancement of odour production that attracts a duced a large temperature elevation that was associated single species of large scarabaeid beetle in its native with receptivity of female florets at the base Brazil, and regulation of maximum T s may prevent over- of the spadix.

Thermogenic Patterns in Philodendron ornatum and P. grandifolium: A Comparative Analysis

Temperature differences between the spadix (male zone) and ambient air for P. grandifolium and P. ornatum showed the same pattern in both species, and otherwise there was little or no difference between air and spadIX temperatures.

Respiration and heat production by the inflorescence of Philodendron selloum Koch

During a 2-d sequence of anthesis, the spadices of the thermogenic arum lily, Philodendron selloum, regulated maximum temperature within a small range by reversible thermal inhibition of respiratory heat production, indicating that there was no net phosphorylation during thermogenesis, heat production being the primary function of high rates of respiration.

Thermogenesis and respiration of inflorescences of the dead horse arum Helicodiceros muscivorus, a pseudo‐thermoregulatory aroid associated with fly pollination

The behaviour and thoracic temperatures of flies emerging from captivity suggests that male floral warming does not enhance their activity, and the pattern of heat production by the males appears related more to time than to ambient temperature, hence the term ‘pseudo-thermoregulation’.

The role of thermogenesis in the pollination biology of the Amazon waterlily Victoria amazonica.

Floral heating is not only associated with attraction, but continues throughout the night when beetles are active inside the flower and increases again when they leave, implying that thermogenesis is an energy reward.

TIME, SPACE, LIGHT AND DARKNESS IN THE METABOLIC FLARE-UP OF THE SAUROMATUM APPENDIX*

In Sauromatum guttatum Schott, the metabolic flare-up which, on the first day of flowering, occurs in the so called appendix of the inflorescence, is triggered by an agent that arises in the male flower primordia when these are exposed to the proper regime of light and darkness.

The Control of Blooming in Sauromatum guttatum (Araceae) by Darkness

It is shown that darkness is the environmental factor which triggers the blooming of inflorescences raised under continuous irradiation, and the moment of the peak in CO2 production during the RC was used as an index of blooming.

The data suggest that the rate of metabolism during flight is altered with regard to the flight effort, but not with regardto temperature-regulation.

Respiratory Mechanisms in the Aroid Spadix

The flowers of Skunk-cabbage, like the spadix tissues of other Aroids, have a rapid, carbon monoxide and cyanide resistant respiration and the mitochondrial system is partially blocked by AA, whereas the microsomal activity is AA-insensitive.

Evidence is presented for the selective inhibition by thiocyanate, alpha, alpha', alpha'-dipyridyl, and 8-hydroxyquinoline of the alternative oxidase pathway, which may therefore contain a non-heme iron protein.
