Date palm (Phoenix dactylifera) can be used as a host plant for sandalwood (Santalum album). Sandalwood is a slow-growing tree species that is prized for its fragrant heartwood, which is used in a variety of products such as perfumes, incense, and traditional medicines.
Sandalwood requires a host tree species for support and protection, and date palm can provide these conditions. When sandalwood is grown as an understory crop in a date palm plantation, the date palm provides shade and protection, allowing the sandalwood to grow in a more favorable environment.
Additionally, the date palm can also provide a source of food and habitat for beneficial insects and other animals, which can help support the health and growth of the sandalwood trees.
