Test results show that after more than 2 years of planting (trees over 2 years old): i) In Ba Vi, the promising varieties are A6, A9 and A10 of Candole State Forest in New South Wales (survival rate 96 , 7-97.8%, fresh leaf essential oil content 2.61%, terpinen-4-ol ratio ≥40%)
clones A37,217, A32.23, A38,317, A 26,218 and A38.39 (survival rate 82,5-92,5%, fresh leaf essential oil content 3,06-3,87%, rate of terpinen-4-ol 40-43%, limonene ratio <
1%, rate of 1.8-cineole <
2.5%)
ii) In Phú Lộc, the promising variety is the Candole A26,218 clones originating from Candole (survival rate 76.7%, fresh leaf essential oil content 4.05%, terpinen-4-ol ratio>
40% , limonene ratio and 1.8-cineole ratio <
1%)
iii) A38 control variety is a promising variety in Ba Vi and Phu Loc (relatively high survival rate, good growth, high and stable oil content and quality - this is the variety that has been approved by the Ministry of Agriculture and Rural Development Recognition)
iv) Tea tree grown in Phu Loc has a relatively low survival rate, growing slower than planting in Ba Vi, requiring appropriate planting and care techniques.
