PERTUMBUHAN SEMAI AQUILARIA MALACCENSIS LAMK DAN GYRINOPS VERSTEEGII GILG PADA BERBAGAI DOSIS FUNGI MIKORIZA ARBUSKULAR

Agarwood-producing plants have fairly slow growth in the seedling phase, the growth of agarwood seedlings of Aquilaria malaccensis Lamk and Gyrinops versteegii Gilg types can be influenced by environmental conditions and the ability of seedlings to absorb nutrients. The use of mycorrhizae in agarwood seedlings can improve the quality of agarwood seedlings. The objectives of this study are to get the best interaction of mycorrhiza doses and types of agarwood against the growth of Aquilaria malaccensis and Gyrinops versteegii that were tried; mycorrhizae that gives the best effect on the growth of Aquilaria malaccensis and Gyrinops versteegii that were tried; and best type of seed agarwood in the type of agarwood that is tested.This research was conducted from February to May 2019. This research uses a completely randomized factorial design method, which consists of two factors.The first factor is M1= mycorrhiza 0 gr/polybag, M2= mycorrhiza 7 gr/polybag, M3= mycorrhiza 14 gr/polybag and the second factor is the type of seed agarwood G1= Aquilaria malaccensis, and G2=Gyrinops versteegii, so there are 6 treatment combinations (M1G1, M1G2, M2G1, M2G2, M3G1, and M3G2). Each treatment combination was repeated 5 times. The parameters observed were, seedling height increase; increase in number of leaves; and increased rod diameter.The results showed that there was no interaction effect between mycorrhizal dose and type of agarwood on all observed variables, but there was a tendency for the best treatment, M2G1 (mycorrhiza 7g/polybag + Aquilaria malaccensis). Mycorrhiza dose which gives the best effect is M2 (mycorrhiza 7g/polybag). And the type of agarwoods that gives the best effect is G1 (Aquilaria malaccensis).Keywords : Agarwood, Mycorrhiza, Aquilaria, Gyrinop
