Kemampuan Isolat Bakteri Selulolitik Dalam Menghasilkan Hormon Iaa (Indole Acetic Acid) Dan Uji Potensinya Pada Benih Padi (Oryza Sativa L.)

---

ABSTRACT
Rice plants (Oryza sativa L.) are very important food crops. Rice productivity
needs to be increased in order to maximize production by improving the quality of
rice seeds. One effort that can be made to improve the quality of rice seeds is to
utilize bacteria containing the hormone indole acetic acid (IAA). The ability of
IAA to stimulate cell elongation modifies certain physiological conditions such as
increasing cell osmotic, increasing water permeability into cells, decreasing cell
wall pressure and increasing cell wall synthesis. The study aims to analyze the
concentration of IAA hormone produced from six isolates from peatland litter and
its effect on rice seeds (Oryza sativa L.). This research was conducted at the Soil
Science Laboratory, Faculty of Agriculture, University of Riau from September
2023 to August 2024. This research was conducted experimentally using a
Completely Randomized Design (RAL) with eight treatment levels. The treatment
levels were repeated three times to obtain 24 experimental units. The parameters
observed were seedling length, root length, germination rate, and germination
power. The results of the observations obtained were analyzed using variance
analysis and further testing with Duncan Multiple Range Test (DMRT) at the 5%
level. The results showed that the administration of Bacillus cereus bacteria (JP 6)
produced IAA hormone which was able to stimulate or help the growth of sprout
length, root length, and also germination power in rice seeds. However, IAA
hormone in all types of single bacteria and consortia was not able to increase the
germination rate of rice seeds.
Keywords: length of sprout, root length, germination power, germination rate
