为了解檀香(Santalum album L.)与不同豆科植物的寄生关系,选取11种具有重要经济价值的豆科植物和檀香一起种植,对檀香叶片的光合特征和株高、地径以及寄主植物根系的吸器大小进行了测定。结果表明,檀香的吸器大小、数量在不同寄主之间存在很大差异,不同寄主对檀香的株高、地径也有显著差异。檀香的优良寄主有美洲合欢(Calliandra haematocephala)、苏木(Caesalpinia sappan)、台湾相思(Acacia confusa)、龙牙花(Erythrina corallodendron);一般的寄主植物有马占相思(Acacia mangium)、降香黄檀(Dalbergia odorifera)、黄槐(Cassia surattensis);不适宜的寄主植物有凤凰木(Delonix regia)、海南红豆(Ormosia pinnata)、银合欢(Leucaena leucocephala)、洋紫荆(Bauhinia blakeana)。同时,檀香的株高、地径及光合特征和吸器数量密切相关。因此,檀香种植时应选择适宜的优良寄主植物。
Studies on Parasitic Relationship between Santalum album L. and Leguminous Plants
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 signiifcant 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.
