MANIPULASI AGRONOMI BUNGA ILES-ILES (AMORPHOPHALLUS MUELLERI BLUME) UNTUK MENINGKATKAN PRODUKSI BIJI
ABSTRACT: Corm of iles-iles
(Amorphophallus muelleri Blume) is extracted for glucomannan production, a
material that is widely used in medicinal, food, and beverage industries.
Increasing demand on glucomannan promotes fast expansion of planting area in
Indonesia, however, seed availability is limited. The objective of the
experiment was to study corm age, planting distance, and planting depth in
order to enhance seed production in A. muelleri. Two experiments were conducted
under paranet of 65% in Leuwikopo Experimental Farm, Bogor Agricultural
University (IPB) from June-November 2015. First experiment used 0- (bulbils),
1-, 2-, 3-, and 4-year-old corms. Second experiment used flowering 3-year-old
corms, arranged by factorial of planting distance (0 × 0 cm and 50 × 50 cm) and
planting depth (0 and 5 cm in depth). Results showed that flowering of A.
muelleri was dependent on corm age, 96% of 3-year-old corms produced flower but
none of the 1- and 4-years-old corms produced flower, whereas 8% of 2-year-old
corms produced flower. Planting distance did not affect flower growth, while
planting at a depth of 5 cm enhanced seed production. Present experiments imply
that application of large 3-year-old corms, planting in dense population and at
depth of 5 cm could enhance seed production of A. muelleri. It needs further
investigation on seed quality from flowering of present treatments.
