摘要：在广东省内3个不同立地条件下开展41个厚荚相思优良家系的区域化试验。结果表明,参试的41个家系在热带北缘试验区内具有较高的材积生长量,分别比南亚热带、亚热带试验区的增加了82.9%和51.7%;各试验区材积生长量超出对照20%的优良家系有6个,其中南亚热带试验区的优良家系为BVG2738,热带北缘试验区的优良家系为128、KN000063,亚热带试验区的优良家系为BVG01127、BVG2734、BVG01108。
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 tropi- cal northern edge, which was 82.9% and 51.7% higher than that in south subtropical and subtropical area, re- spectively. 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.
