Acacia auriculiformis is a high value forest species; it can be planted in various climatic and soil conditions. Recently, some high quality and fast growing clones of A. auriculiformis have been selected by the Research Centre for Forest Tree Improvement. The objective of the project was to identify the best method to vegetatively propagate clones of A. auriculiformis and establish pilot plantations of the species using selected clones. Some of the main results can be highlighted:
– IBA is the most suitable growth regulator for rooting of the cutting. The best concentration of IBA for cutting was 0.75%.
– The best timing for cutting propagation of A. auriculformis in northern Vietnam was between April and October. – The spacing of 3m x 3m was suitable for initial establishment of plantation.
– Fertilizer treatments of 200g micro-fertilizer and 200g Thermon-photsphate or 200g micro-fetilizer plus 200g NPK per tree were suitable for plantation.
– Using selected clones of A. auriculiformis and suitable silvicultural applications increased volume production of plantation by 160-200% higher than those using unimproved seedling.
