Pembentukan Akar Jeruk Siam (Citrus Nobilis Lour.) Asal Kampar Dari Tunas In Vitro Pada Media ½ Murashige Skoog Dengan Penambahan Indole Butyric Acid (Iba) Dan Naphthalene Acetic Acid (Naa)
Orange is very popular as a fruit of consumption in Indonesia, including Riau. One type of citrus which is the mainstay of commodity cultivation in Riau province is siam orange (Citrus nobilis Lour.). Siam orange has a sweet, fragrant aroma and thin fruit skin. Siam orange cultivation needs improvement for having the best quality plants. One effort that can do is in vitro culture. The study aimed to determine the best Indole Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) concentrations to trigger the formation of siam orange (C. nobilis Lour.) roots. This study was conducted at the Integrated Biology Laboratory, Department of Biology, Riau University from September 2018 to April 2019. This study using a Completely Randomized Design (CRD). The result of this study shows that the rooting percentage obtained 100% on all treatments. The faster rooting obtained in 2 mg/L IBA treatment (7,67 days after planting). The highest number of roots obtained in the combination of 0.5 mg/L NAA with 1.5 mg/L IBA (2.67 units). The longer root obtained in the combination of 1.5 mg/L NAA with 0.5 mg/L IBA (2.27 cm).
