Abstract

Sandalwood (Santalum album L) is one of the tropic plants that have high economic
value. Sandalwood exploitation in East Nusa Tenggara province has very long
history perhaps more than 1000 years therefore unforgetable. Now a days
sandalwood was categorized as rare plant. One of the several ways to conquer
the rare of sandalwood is to build the garden of sandalwood seeds in Kian Rai
Ikun, Belu Regency. Some steps of these activities are, to inventory the mother
seeds trees in Belu and Timur Tengah Utara Regency, seeds collecting, seed
germination and furthermore sandalwood seedlings are planted in the garden of
sandalwood seeds in Kian Rai Ikun, Belu regency. This garden is located about
450 m above sea level (asl).
On inventory activity were found 5 mother seeds trees located in Biau (Bi) about
500 m asl, Alas (Al) 500 m asl, Haitimuk (Ha) 100 m asl, Oesena (Oe) 500 m
asl and Tialai (Ti) 450 m asl. Planting of sandalwood seedling in this garden are
coordinated to available planting plot. Every planting plot was grown about 200
– 250 sandalwood seedlings from the same mother seeds tree. Some activities
to maintain sandalwood seedling in the garden after planting time are, watering,
weeding and pruning the branch. The aim of branch pruning on sandalwood
trees is to protect the plant from wind disturbance in order not fall down. In our
experience sandalwood seedling fall down easily if seedling has dense of branches
and leaves.
This research was purposed to study the effect of mother seeds trees and branch
pruning on sandalwood growth in the field. The result shown that branch pruning
did not give significantly different on sandalwood growth but the mother seeds
trees gave significantly different on sandalwood growth in the field during 1 –
10 months after pruning. The sandalwood plants from Haitimuk mother seeds
tree possess the highest in height and branch growth than other plants, while the
sandalwood plants from Oesena mother seeds tree possess the lowest in height
and branch growth. The growth of sandalwood in field followed the models of
logistic growth with high determination coefficient about more than 0. 85.
