My work focuses on testing the effects of N2-fixing and non-N2-fixing on ecophysiological characteristics and nitrogen (N) nutrition of Santalum album. Our results may provide N management strategies for successfully mixed plantation of S. album with rosewood Dalbergia odorifera, allowing the development of a superior methodology for the concurrent plantation of these two valuable timber species. Two fascinating articles in 2013 and 2014 have been published on Tree Physiology, which were praised for “very exciting and important study for plant-parasite interactions, especially for the role of legumes in sandalwood biology (See e-mail from the journal of “Tree Physiology” on 28-May-2014)” by editors and reviewers. At present over 1,000 ha mixed S. album/D. odorifera have been planted in Southern China, which provides an excellent practice example for the existing sandalwood plantation industry with another high-value woody species.
