Formulasi Inokulan Jamur Pembentuk Gubal Gaharu pada Tanaman Ketimunan (Gyrinops versteegii)

Abstract

This study aims to find the most effective formulation of the gaharu agar wood forming fungi inoculants
which infect Gyrinops versteegii plants, thus producing high quality agar wood. The method used in
this research is the randomized block design (RBD) with three replication. The treatments were two
fungi as inoculant applied saperately each and a combination of Rhisopus sp. and Fusarium sp. in the
form of solid and liquid. The treatments tested were: (A) Fusarium solani fungi inoculant in solid form,
(B) Rhisopus sp.fungi inoculant in solid form, (C) Mixture of Rhisopus sp. and Fusarium solani fungi
inoculants in solid form, (D) Fusarium solani fungi inoculant in liquid form, (E) Rhisopus sp.fungi
inoculants in liquid form, (F) Mixture of Rhisopus sp. and Fusarium solani fungi inoculants in liquid
form, and (G) A combination of solid and liquid of Rhisopus sp. and Fusarium solani fungi inoculants.
The parameters measured were the agar wood formed: agar wood fragrance level, color of agar wood
and resin content of the agar wood. Furthermore, the data is analyzed statistically by analysis of
variance. The results showed that, treatments of inoculants formulations significantly affects the aroma
and resin content of agar wood. Formula of G (a combination of solid and liquid Rhisopus sp. and
Fusarium solani fungi inoculants) and F (a combination of liquid Rhisopus sp. and Fusarium solani
fungi inoculants) produced agar wood of the highest quality compared to other formulas. Formula G
and F produced each agar wood with black and blackish-brown colour, with strong aroma (fragrance),
and a resin content of 7.69% and 6.98%.
