Which Trees Serve as Hosts for Sandalwood Trees
Sandalwood trees, particularly Santalum album, have specific host trees that they rely on for growth and development. These trees are hemiparasitic, meaning they can photosynthesize but also derive nutrients and water from other plants. Understanding which trees serve as hosts for sandalwood is crucial for successful cultivation.
Common Host Trees for Sandalwood
Several tree species are known to be hosts for sandalwood. Some of the most common hosts include:
Acacia Species - Various species of Acacia are often used as hosts for sandalwood. Eucalyptus Species - Some Eucalyptus trees can serve as hosts for sandalwood. Casuarina Species - These trees are also known to support sandalwood growth. Terminalia Species - Certain Terminalia trees can act as host plants.While sandalwood can grow on a range of host trees, the presence of compatible host species is crucial for its growth and development. Proper site selection and understanding of local ecology are important for successful sandalwood cultivation.
Additional Information and Studies on Host Trees
Over the years, researchers have identified various host trees that can be used for sandalwood cultivation. Some commonly used hosts include:
Acacia nilotica Pongamia pinnata Melia dubia Wrightia tinctoria Cassia siameaStudies have shown that nitrogen-fixing trees are particularly preferred as hosts. For example, jamun (Syzygium cumini), tamarind (Tamarindus indica), and other leguminous trees are often used. In the initial years, Acacia species can be used as primary hosts, which can last for 2 to 7 years. Secondary host trees become crucial for the growth and oil yield of the sandalwood species from the 7th year throughout its lifetime.
The host-to-sandalwood tree ratios are very low, and while these trees are often planted together, the relationship between the host and the sandalwood in nutrient exchange is a topic of ongoing research.
Successful Host Trees in India and Australia
In India, 4 to 5 species have been found to be successful as hosts for sandalwood, including:
Dalbergia latifolia - Also known as teak Pongamia pinnata - Also known as pongam tree Neem (Azadirachta indica)Studies conducted in Australia have shown that Dalbergia is the best with high growth and survival rates. However, in India, sandalwood primarily grows everywhere, and the success of essential oil extraction is dependent on nitrogen-fixing hosts.
Conclusion and Further Research
Proper site selection and understanding of local ecology are crucial for successful sandalwood cultivation. The role of host trees in the growth and development of sandalwood is significant, and ongoing studies are being conducted to understand their relationship better.
