The effect of mycorrhiza on the growth of Ylang-Ylang seedlings

Abstract Ylang-ylang (Cananga odorata forma genuina Steenis) is a plant with high economic value and many benefits. Mycorrhizal application is necessary to obtain a quality mother plant. Therefore, a study on the mycorrhiza effect on ylang-ylang growth was needed, especially in the seedling stage. This study aimed to analyse the impact of mycorrhiza infection on the development of ylang-ylang seedlings. The method used in this study was the isolation of Claroideoglomus etunicatum spores. Ten of each spore was inoculated onto the sterilised roots (using 5% Natrium hypochlorite) of the three-month-old ylang-ylang seedlings and then planted on zeolite media and soil in a 6 x 10 cm pottery, which was then transferred to each pot 13 cm in diameter and 16 cm in height. For comparison, zeolite and soil media were used without the addition of mycorrhiza. The result of this study showed that the application of mycorrhizae using soil media had the highest increase in height (4.19 cm), diameter (0.72 mm), number of leaves (2.6 strands), and number of buds (0.8 leaf buds) compared to other treatments.
