Abstract

Nutmeg (Myristica fragrans Houtt.) is a native commodity of Indonesia. Propagation of this plant is relatively difficult and takes a long time for germination because of its hard seed coat. This study aimed to evaluate the effect of scarification and gibberellin (GA) application on the nutmeg seed germination. Factorial completely randomized design (CRD) was used in this study. The first factor was scarification (S0: without scarification, S1: scarification at part of the radicle out, S2: scarification at all the seed surface, and S3: seed coat wounding) and the second factor was GA soaking (0, 50, 100, 150 ppm) for 24 hours, each of combination treatments with six replications. The parameters of germination (days to germinate, germination, growth potential, percentage of germination), growth (root length, plant height, number of leaves, and girth), the morphological and anatomical structure of nutmeg seed were observed. Data of germination and growth were analyzed using Anava to DMRT at the level of 95% using SPSS, while data of morphological and anatomical structure were analyzed descriptively. The results showed that scarification (seed coat wounding) was the best treatment to enhance germination, while 100 and 150 ppm GA application of the decreased effect on all parameters of germination and growth. Combination of scarification (wounding seed coat) and soaking on 150 ppm of GA (G3S3) was the best treatment for improving germination parameters (day germinate until 9,50 day after plating, 88,88% of germination ability, germination percentage to 91,66%, growth potential to 97,22%) and growth parameters (root length to 13,67 cm, plant height to 24,95 cm, leaf number to 3,75, and girth stem to 1,94 cm). The main barrier of nutmeg germination was caused by a hard seed coat. That consists of ligneous sclerenchyma cells.
