| elevated atmospheric partial pressure of carbon dioxide and dry matter production of konjak (amorphophallus konjac k. koch). | konjak (amorphophallus konjac k. koch) was grown under normal (350 μbar) or enriched (700 μbar) co2 partial pressure in glasshouses kept at 33/26°c. doubling the co2 partial pressure resulted in twice the yield of corm because the net co2 assimilation rate doubled and, due to the simple source-sink relationship, the increased production was partitioned to the corm. the response to co2 of assimilation by konjak is discussed in relation to its original habitat in the tropics. | 1983 | 24458526 |
