Abstract

This research aims to investigate the influence of media (topsoil and cocopeat) and seed treatment (control, immersion, cracking, and stripping) on the growth of nyamplung seeds from Talise Island on 3 months old. This research using Completely randomized design method with observations viability, height, diameter, robustness seedlings and seed quality index.  Results of tests known that character nyamplung growth is influenced by the media and seed handling. Cocopeat media will improve  the viability but debase of growth, so that the necessary weaning with a more fertile medium. Handling seed by stripping the shell has a good influence on the growth and quality of seeds. Based on research, nyamplung requiring scarification with cocopeat media and stripping the shell.

Abstract

It was estimated that North Sulawesi needs 9,870,093.33 coastal vegetation seeds to rehabilitate the damage of coastal ecosystems which reach 14,805.14 ha, where the largest area 13.884 ha located in other land use. This study aims to provide information of seed germination techniques in Permanent Nursery Kima Atas, Manado. Research was arranged in complete randomized design as factorial with three replications. Ketapang (Terminalia cattapa) will obtain high viability in fluctuation of temperature and humidity, i.e used sand media, without wildlings and placed under 25% shade and rain. Keben (Baringtonia asiatica) through the incision and decay that placed in the open location will obtain viability until 90% within 2 months. Nyamplung (Calophyllum inophyllum) requires shell splitting in order to improve the viability and it can be done by cracking and stripping.
