✦ Synopsis

Konjak (Amorphophallus konfac K. Koch) was grown under normal (350 t~bar) or enriched (700 ~bar) CO~ partial pressure in glasshouses kept at 33/26 °C. Doubling the CO 2 partial pressure resulted in twice the yield of corm because the net CO 2 assimilation rate doubled and, due to the simple source -sink relationship, the increased production was partitioned to the corm. The response to CO 2 of assimilation by konjak is discussed in relation to its original habitat in the tropics.
