Abstract

The primary host of sandalwood seeds (Santalum album L.) which is widely used in the nursery process is Alternanthera sp. However, the local name given to this primary host is same as that given to Portulaca sp. The same local name for these two-different species may cause mistakes in the use of the primary host during the cultivating process of sandalwood. Meanwhile, the ability of the Portulaca sp. as the primary host is unknown. Information about the right radiation intensity of the sandalwood seedling is still limited. The study aims to analyze the growth of sandalwood seedlings grown with primary host of Alternanthera sp. and Portulaca sp. at different radiation intensities. The completely randomized design with two treatments factor were used, namely differences in shade levels (without shade, 25, 50, and 75%) and differences in the types of primary hosts. The result showed that the primary hosts of Alternanthera sp. have the best growth for sandalwood seeds compared to sandalwood seedlings planted with Portulaca sp. The shading must be adjusted to the type of primary host. Sandalwood seeds grown with Alternanthera sp. as primary hosts grow best at 50% and 75% paranet shade conditions, in radiation range of 9.86–12.17 MJ/m2/day. Sandalwood seeds planted with Portulaca sp. as a primary host grow best in 25% paranet shade, that is at average radiation of 13.62 MJ/m2/day. The use of Alternanthera sp. and shade provision (50–75%) is highly recommended in sandalwood seedlings. Keywords: haustoria, hemiparasite, primary host plant, sandalwood, symbiosis

Abstract

Sandalwood (Santalum album L.) seedlings planted with different primary host plants should require different amounts of water. In practice, however, sandalwood seedlings with different primary host plants are irrigated with similar amount of water. Thus, it is interesting to study the amount of water expressed as evapotranspiration for the sandalwood seedlings and their primary host plants because there are hemiparasitic symbiosis plants in one planting medium. The purpose of this research was to compare and analyse evapotranspiration (ET) and water use efficiency (WUE) of sandalwood seedlings with different primary host plants, namely chili (Capsicum annum), krokot (Alternanthera sp.), and sengon (Albizia chinensis). The experiment was conducted in a greenhouse and designed using completely randomized design. Results showed that different primary host plants already influenced ET at 6 days after sowing of primary host (DASH). The sandalwood seedlings with chili and krokot as primary hosts, had the highest ET during 6-22 DASH. From 24 to 36 DASH, ET for all types of host plants were similar. After 36 DASH, ET of sandalwood seeding with primary host sengon increased, and had the highest ET. Sandalwood seedling with primary host krokot had the highest WUE to produce sandalwood above ground biomass with value 0.3 g/l during the 0-3 weeks after sowing of primary host (WASH), 0.6 g/l during the 3-6 WASH, and 0.9 g/l during 6-9 WASH.
