ABSTRACT:

The paper includes information on the ecology and biology, distribution and content of glucomannan in tubers of the species Amorphophallus yuloensis H. Li in Vietnam. Amorphophallus yuloensis belongs to a group in the genus with short peduncles. It differs from other species in the group by having a much smaller inflorescence, stout conical appendix and violet blue berries. This is one of five species in Vietnam whose tubers contain high glucomannan content for the food industry. Glucomannan content in its tuber is about 29.2% of dried weight.
