Abstract

Michelia alba L. is locally known as Cempaka Putih and belongs to Magnoliaceae family. In this study, three experiments were conducted namely seed germination based on scarification treatment, seed germination based on storage and early seedling growth. Altogether 1000 seeds were used. For scarification treatment, five treatments were applied. They were sown directly (T0), chipping with razor blade (T1), abrasion with sandpaper (T2), acid scarification (T3), and hot water scarification (T4). For storage experiment, four storages had been done; that are seeds were stored for one month (S1), two months (S2), three months (S3) and four months (S4). All the seeds were sown using Completely Randomized Design (CRD). For early seedling growth, 30 seedlings from experiment one were used. The seedlings were transplanted into three types of growing medium namely topsoil (MI), sawdust (M2), and mixture of topsoil and sawdust 1: 1 (by volume) (M3). Parameter taken were height of seedling, number of expanded leaves and diameter of stem were taken. From experiment one, seeds from T, had highest germination percentage, 63% meanwhile for experiment two, the seedlings responded differently in different medium. Seedlings recorded highest increment in height in M3 with 1.67cm, highest increment of expanded leaves was from M1 with 4 leaves and highest increment of diameter from M2. However, seedlings growth as a whole was not affected significant by different types of growing medium.
