摘要 在福建省诏安国有防护林场引种不同种源(家系)的交趾黄檀,造林2年后通过对其胸径、树高和存活率指标测定分析,结果表明:交趾黄檀不同种源(家系)间幼树生长差异达显著或极显著水平,造林2年后,平均胸径为2.92~6.19 cm,平均树高为2.78~4.79 m;而保存率差异不明显,为93.3%~100%。经综合评判,初步选出初期生长表现较好的2个优质种源和7个优质家系。 Different provenances(families)of Dalbergia cochinchinensis were introduced in Zhaoan State-owned Protection Forest Farm of Fujian Province.The DBH,tree height&survival rate were determined after two years of afforestation.Result shows that:There are significant or extremely significant differences in growth of young trees among different provenances(families).The mean DBH&tree height range from 2.92 cm to 6.19 cm&2.78 m to 4.79 m,respectively.However,there is no significant difference in survival rate,which is between 93.3%to 100%.After comprehensive evaluation,two fine provenance and seven families were selected to grow well in the early stage.
