Abstract

Nyamplung (Calophyllum inophyllum L.) and kenari (Canarium indicum L.) have many benefits and potentials (historical, economic, energy, ecological, social) so it is necessary to propagate plants to increase their productivity. This study aims to determine the physical condition of seeds, seed health (pests and diseases carried by seeds), and optimal germination media of nyamplung and kenari seeds with soil (control) media treatment, zeolite, cocopeat, soil and sand mixture (1:1 v/v). The good physical conditions of nyamplung seeds are thick and hard round shape, ivory yellow color, when pressed it is not soft, the average weight is 3 g, the average height is 2.6 cm, and the average diameter is 1.7 cm. The good physical conditions of kenari seeds are a tapered oval shape with a very hard shell, light brown in color, an average weight of 6.9 g, an average height and diameter of 3.7 cm and 1.9 cm, respectively. The fungi carried by nyamplung seeds are Rhizoctonia sp. and Pythium sp., while in kenari seeds is Collectotrichum sp.. The best germination medium for nyamplung seeds is zeolite, while the best germination medium for kenari seeds is a mixture of soil and sand (1:1 v/v). The results of this study provide information on the physical condition, seed health (pests and diseases) carried by seeds so that preventive and curative efforts can be made in their cultivation, as well as the optimal media for germination so as to produce superior quality seedlings.
