Abstract
Shorea leprosula is a major timber producing trees in Indonesia and one of an essential commodity. To get high quality of Shorea leprosula must be developed by cultivation techniques in order to obtain the quality plant‟s growth of Shorea leprosula. The development of biotechnology in forestry provides an opportunity to use environmentally friendly technology through the application of mycorrhizal. This study aimed to determine the influence of mycorrhizal application on seedlings quality and determine the best dosage to increase growth of seedling‟s Shorea leprosula in peat medium. The research used completely randomized design (CRD) with 5 treatments and 10 replications. The treatments consisted of : (M0) without application of mycorrhizal, (M1) application of mycorrhizal with the dosage 10 gr/polybag, (M2) application of mycorrhizal with the dosage 20 gr/polybag, (M3) application of mycorrhizal with the dosage 30 gr/polybag and (M4) application of mycorrhizal with the dosage 40 gr/polybag. Mycorrhizal application can increase the quality of seedlings Shorea leprosula in peat medium. The best dosage indicated on application of mycorrhizal in the dosage 20 gr/polybag (M2) with survival persentage (100%), height growth (3,36 cm), diameter growth (0,17 cm), dry weight crop (2,19 gr), root dry weight (0,63 gr) and top-root ratio (2,28).
