“…Being semi-parasitic in nature, sandalwood plants require host plants that have the potential to grow in combination and provide nutrients and water for better growth of sandalwood plants [ 15 ]. Further, in nature, more than 300 plant species can serve as host plants for sandalwood tree by providing nutrients and water through a specialized organ called the haustorium, particularly in the initial stages of growth [ 16 , 17 ], since the sandalwood roots lack root hairs [ 18 ]. Specifically, the growth of parasitic angiosperms is regulated by host root-derived chemical signals [ 19 ] and 70% of seedlings are capable of producing haustoria within thirty days of germination [ 20 ].…”

“…Sandalwood water and photosynthetic efficiency are primarily determined by how the host plant responds to environmental factors [ 17 ]. Thus, the selection of the appropriate host becomes more crucial, since the host species also influences the haustorial growth, the composition of organic acids, sugars, and amino acids in the xylem stream, the carbon assimilation rate, and the chlorophyll content in sandalwood plants [ 18 ]. Hence, it is imperative to promptly identify appropriate host plants that can thrive in challenging conditions, like in saline soils.…”

“…Previously, sandalwood was shown to prefer legumes as hosts, likely because of the legumes higher levels of glutamine synthase activity [ 24 ]. However, among leguminous plants, Acacia acuminata , a resilient plant species, offers several advantages in terms of improved growth and a more favorable K:Ca ratio than less resilient species such as Allocasuarina huegeliana [ 18 , 25 ]. In general, three factors—the choice of sandalwood for hosts, the ability of hosts to tolerate salinity, and the regulation of physiological and biochemical processes in sandalwood—likely determine the salinity tolerance and growth of sandalwood in saline environments.…”

Salinity is one of the most significant abiotic stress that affects the growth and development of high-value tree species, including sandalwood, which can also be managed effectively on saline soils with the help of suitable host species. Therefore, the current investigation was conducted to understand the physiological processes and antioxidant mechanisms in sandalwood along the different salinity gradients to explore the host species that could support sandalwood growth in salt-affected agro-ecosystems. Sandalwood seedlings were grown with ten diverse host species with saline water irrigation gradients (ECiw~3, 6, and 9 dS m−1) and control (ECiw~0.82 dS m−1). Experimental findings indicate a decline in the chlorophyll content (13–33%), relative water content (3–23%), photosynthetic (27–61%) and transpiration rate (23–66%), water and osmotic potential (up to 137%), and ion dynamics (up to 61%) with increasing salinity levels. Conversely, the carotenoid content (23–43%), antioxidant activity (up to 285%), and membrane injury (82–205%) were enhanced with increasing salinity stress. Specifically, among the hosts, Dalbergia sissoo and Melia dubia showed a minimum reduction in chlorophyll content, relative water content, and plant water relation and gas exchange parameters of sandalwood plants. Surprisingly, most of the host tree species maintained K+/Na+ of sandalwood up to moderate water salinity of ECiw~6 dS m−1; however, a further increase in water salinity decreased the K+/Na+ ratio of sandalwood by many-fold. Salinity stress also enhanced the antioxidative enzyme activity, although the maximum increase was noted with host plants M. dubia, followed by D. sissoo and Azadirachta indica. Overall, the investigation concluded that sandalwood with the host D. sissoo can be successfully grown in nurseries using saline irrigation water and, with the host M. dubia, it can be grown using good quality irrigation water.

“…Due to parasitism, sandalwood retrieves 70 percent of the water and nutrients from the roots of its host species through xylem/phloem connections made by the Haustorium organ (Rocha et al, 2017;Mohapatra and Avni, 2022). Sandalwood absorbs nutrients such as Nitrogen, Phosphorus, Potassium and Calcium from roots of host plant (Srikantaprasad et al, 2022). The literature revealed that over 300 plant species could serve as hosts in tropical and sub-tropical environments (Srikantaprasad et al, 2022).…”

Sandalwood is semi root parasite plants that required host plant for water and nutrients. So, for successful sandalwood plantation, it is important to study the host parasite interactions and role of external supply of water and nutrient, both theoretically and practically. To find out long-term host species for sandalwood, a randomized block design experiment was conducted to identify the suitability of host and effect of externally supplied nutrient medium on sandalwood planted with five selected host (Alternanthera sp., Azadirachata indica, Dalbergia sissoo, Melia dubia, and Aquilaria malaccensis) and without host species. After 180 days of establishment, morphological traits were recorded and noted that plant height, collar diameter and root length was higher in Dalbergia sissoo and Melia dubia as compared to other host species. Significant enhancement in morphological traits was recorded with external supply of Hoagland nutrient medium. Similarly, higher shoot biomass and root biomass were noted in Dalbergia sissoo and Melia dubia under control as well as with externally supplied nutrient medium. While, maximum haustorial connections were formed with Dalbergia sissoo over studied host species. On the other hand physiological trait such as chlorophyll content was abundant in sandalwood grown with Dalbergia sissoo. Physiological parameters such photosynthetic rate, transpiration rate were higher in sandalwood cultivated with Dalbergia sissoo. Macronutrient such as nitrogen, phosphorus and potassium content was also higher in Dalbergia sissoo and Melia dubia. The results revealed that sandalwood could be grown successfully with Dalbergia sissoo and external supply of nutrients might enhance the growth and physiology of sandalwood.
