Abstract

Screening for salt tolerance of fast growing tree species in nutrient solution, was conducted with 9 seed sources in 5 species, including Acacia  ampliceps (15762), Acacia  ampliceps (18425), Acacia  plectocarpa (19983), Acacia  plectocarpa (19931), Acacia  leptocarpa (16176), Acacia  leptocarpa (19006), Acacia  colei (19984), Acacia  colei (19958) and Eucalyptus  camaldulensis. The seedlings were grown in nutrient solution (deep water culture system). Input NaCl 3.5 g for adjusting EC (Electrical Conductivity) to 8 ds/m. The Randomized complete block design with 3 replications, 9 treatments was applied. Diameter at root collar, total height and number of leaves of all seedlings were measured every two weeks. 


The results showed that Eucalyptus camaldulensis provided the best growth rate, followed by Acacia ampliceps (18425) and Acacia colei (19984), respectively. however number of leaves of A. leptocarpa (19006) and A. colei (19958) which were grown in treatment pots is less than those in control pots. Eucalyptus camaldulensis provided the highest above ground biomass per tree at 12 weeks which was 57.57 g/tree. Acacia plectocarpa (19983) provided the least above ground biomass which was 9.47 g/tree. While, Acacia colei (19984) provided the highest below ground biomass which was 11.68 g/tree.
