N2  - Experiments were conducted at College of Forestry. Kerala Agricultural 
University. Vellanikkara. Thrissur during 1995-96 to elucidate the various 
aspects of parasitisation behaviour of sandal (Santalum album Linn.). 
Parasitisation behaviour of sandal on selected agricultural crops occurring in the 
homesteads of Kerala. response of selected sandal-host combinations to 
manures and fertilizers and uptake and translocation of nutrients and 
photosynthates by sandal-host associations were the principal aspects 
investigated. Pot culture experiments involving a number of hosts like coconut, 
cashew, banana, black pepper, jack, mango, rubber, casuarina, erythrina and 
redgram were conducted as part of the study. 
The results indicated that, growth parameters of the sandal seedling like 
total dry weight and number of haustoria varied significantly depending on the 
host associated with sandal. Maximum growth of sandal was observed in 
association with the host - Casuarina equisetifolia. No significant decrease was 
observed in the growth of any of the hosts consequent to the parasitisation by 
sandal. Host is the principal factor governing the growth of sandal and fertilizer 
levels tried in this experiment had not caused any significant influence on the 
growth of sandal seedlings. In, view of the favourable influences by the host 
complex of a good and bad host together ie., casuarina + erythrina, on sandal's 
growth, the possible competitive/complementary effects of multiple host 
combinations on sandal's growth, need be investigated in greater detail. 
 
Sandal plants can take up elements like calcium, sulphur and 
phosphorus directly from soil and a small fraction of these are also obtained 
from host. Carbon compounds also are translocated between sandal and 
hosts. The same host differed in its ability to supply different elements to 
sandal ie., in the supply of phosphorus to sandal casuarina was better while 
carbon compounds were optimally supplied by erythrina. So instead of 
providing a single host to sandal, a variety of good hosts should be provided 
in the field for ensuring a more optimal growth of sandal. Anatomical studies 
showed that, sandal roots can establish direct vascular connections with host 
roots through haustoria.
