Odor-Production on amorphophallus titanum
What's Happening
Sulfur-containing amino acid metabolism produces dimethyl disulfide and dimethyl trisulfide as primary odorants during female flowering phase, while putrescine (derived from arginine via ornithine decarboxylase pathway) contributes additional nitrogenous compounds. Free methionine serves as the sulfur substrate for volatile production, rapidly depleted during thermogenic activity to attract carrion beetles and flesh flies for pollination.
How to Fix It
- 1
Provide sulfur-containing fertilizers (ammonium sulfate) during pre-flowering vegetative growth
- 2
Monitor soil nitrogen levels to ensure adequate precursor availability for putrescine synthesis
- 3
Maintain consistent watering to support amino acid transport to inflorescence tissues
- 4
Document odor intensity changes to track pollination readiness
How to Prevent It
Ensure adequate sulfur and nitrogen availability in soil during vegetative growth to support odor compound precursor synthesis. Avoid over-fertilization which may disrupt amino acid metabolism balance.
