摘要:对广东省乐昌市山地营造的5 a生闽楠福建种源、家系联合选择实验林进行生长调查,结果表明该林分胸径、树高和单位面积蓄积分别为2.21 cm、2.60 m和2.06 m^3/hm^2,该指标符合我国林业行业标准"楠木培育技术规程"中一般栽培区的闽楠生长指标,支持该标准将广东省北部划为闽楠的一般栽培区的栽培区划。种源水平上的方差分析结果表明,种源间和区组间的胸径、树高和单位面积蓄积量均具有显著或极显著差异,说明种源和坡位对闽楠生长均具有显著影响。通过多重比较,以与最低值有显著差异的作为入选条件和项目考核指标,选出的优良种源有福建永安、政和、尤溪等3个种源,其平均单位面积蓄积量均超过3.00 m^3/hm^2。通过种源-家系联合选择方式、以高于入选种源材积平均值为入选条件,从福建永安、政和、尤溪3个种源中共选择出优良家系17个。
Growth performance of a pilot plantation consisting of 11 provenances, totaling 107 families was assessed in terms of DBH, height and volume per hectare in Phoebe bournei from Fujian in Lechang, Guangdong. The DBH, height and volume per hectare were 2.21 cm, 2.60 m and 2.06 m3/hm2 respectively. Significant or highly significant difference was found among provenances and blocks, meaning both provenance and slope play a role in growth performance of Phoebe bournei. The top three provenances in terms of volume per hectare, i.e. Yong'an, Zhenghe, and Youxi of Fujian, were regarded as elite provenances for Guangdong. Seventeen families were selected as elite families from the three provenances by provenance-family combined selection, their volume per hectare were higher than mean volume per hectare for each provenance.
