Abstract:
The regionalization test using forty one excellent families of Acacia crassicarpa was carried out at three different sites in Guangdong. The results showed that the tested families had high volume growth in the tropical northern edge, which was 82.9% and 51.7% higher than that in south subtropical and subtropical area, respectively. Six families were selected as excellent families, with the more than 20% volume growth higher than CK. The excellent families including BVG2738 planted in the South subtropical area, and 128, KN000063 planted in the tropical northern edge, BVG01127, BVG2734, BVG01108 planted in the subtropical area.
