Abstract:In order to understand the parasitic relationship between Santalum album L. and leguminous plants, eleven leguminous species were planted with S. album. The leaf photosynthetic characters, height and base diameter of S. album and its haustoria number and size were studied. The results showed that number and size of haustoria, height and base diameter of S. album had significant differences among different hosts. The excellent hosts for S. album were Calliandra haematocephala, Caesalpinia sappan, Acacia confusa and Erythrina corallodendron, and Acacia mangium, Dalbergia odorifera and Cassia surattensis were just general hosts, while Delonix regia, Ormosia pinnata, Leucaena leucocephala and Bauhinia blakeana were unsuitable hosts. Meanwhile, the height and diameter, leaf photosynthesis characters of S. album had close relation with number of haustoria parasitized on roots of leguminous plants. So, the plantation of S. album should choose appropriate host plant.
