枫香优良家系选择试验初报

在广东省韶关曲江林场对14个枫香（Liquidambar formosana）家系开展子代测定田间试验。方差分析结果表明，0.5 a生地径生长差异显著（P<0.05），1.5 a和3.5 a生树高、地径生长差异极显著（P<0.01），0.5 a生树高生长差异不显著，初步筛选出MZDB505、MZPY504和FXMPY0901共3个表现优异的家系。

Study on Early Test of Liquidambar formosana Hane Families in ShaoGuang

14 families of Liquidambar formosana Hance were testde in ShaoGuan City. The growth an form indexes of 0.5,1.5 and 3.5 year-old trails such as height and base diameter were measured and analyzed. The results showed that in addition to height growth in 0.5 year-old difference is not obvious, the differences of two growth indexes among families reached a certain significant level respectively in other time tested. The heritability of height and base diameter were 0.66~0.78, which indicated that the early height and base diameter were strongly genetic control.
