TEKNIK PERBANYAKAN CEPAT SUMBERDAYA GENETIK ILES-ILES UNTUK MENDUKUNG PERCEPATAN KOMERSIALISASI SECARA BERKELANJUTAN
ABSTRACT: Increasing demand on
glucomannan as healthy diet in develop countries, promotes higher planting area
of Amorphophallus. Iles-iles corm (Amorphophallus muellen) contains high
percentage of glucomannan. In order to meet with increasing demand, providing
mass planting materials is a great concern in Indonesia. Therefore, the study
on skin corm and bulbil as propagation materials was conducted. In the first
experiment, bulbil with different size and section, i.e., very small, small,
medium and large, and half section and 1f4 section were used. In the second
experiment, we evaluated the prospect of skin corm as propagul where different
size of skin corm was used, i.e., 1 em x 1 em, 2 em x 2 em, and 4 em x 4 em.
Results showed that both bulbil and skin corm could be utilized as
prospectivepropagules of iles-iles. Propagation using bulbil was more superior
as compared to skin corm. Bulbil of both whole and sectioned had high emergence
of bud (> 90%), except very small sized ones. Very small bulbil (diameter
less than 1 em) resulted in ca 605 of emergence. Skin corm sized 4 em x 4 em
produced equal emergence to medium bulbil. In general, increasing size of skin
corm increased success of emergent bud. Delaying emergence on small sized skin
corm could be assessed by smaller nutrient reserved. Most unseccessemergence of
small sized skin and very small bulbil was due to decay of the propagules. These
experiments implied that both bulbils and skin corm could be used as mass
propagules for iles-iles production.
