摘    要:为进行闽楠优良产地的早期选择,对采自贵州、浙江及福建3省17个闽楠产地的种子进行了容器育苗试验,测定了不同产地1~2年生苗木的苗高、地径、根系指标及生物量。结果表明:不同产地闽楠苗高、地径、总根长、总根表面积及生物量差异显著,其中1年生苗苗高、地径、总根长、总根表面积及生物量变幅分别为10.10~14.70 cm、2.02~2.93 mm、55.57~133.22 cm、10.92~30.90 cm2、0.37~1.04 g; 2年生苗苗高、地径、总根长、总根表面积及生物量变幅分别为28.02~52.00 cm、4.00~5.05 mm、189.00~299.44 cm、118.01~249.43 cm2、3.66~14.13 g。通过主成分综合评价,初步筛选出福建建瓯、浙江丽水、贵州赤水及遵义为贵阳地区闽楠苗期生长表现较好的产地。

Genetic variation among origin locations of Phoebe bournei (Hemsl.)Yang and a preliminary selection based on seedling growth and root traits
Abstract:For early selecting excellent origin location of Phoebe bournei, we collected seeds from 17 Phoebe bournei origion locations in Guizhou, Zhejiang and Fujian Province and conducted container seedling test, to determine differences of the seedling height, ground diameter, root indices and biomass of both 1 and 2 years old Phoebe bournei seedlings. The results showed that there were significant difference in seedling height, ground diameter, total root length, total root surface area and biomass among different origin locations. The height, ground diameter, total root length, total root surface area and biomass of one year Phoebe bournei seedlings ranged respectively as follows:10.10-14.70 cm,2.02-2.93 mm, 55.57-133.22 cm, 10.92-30.90 cm2and 0.37-1.04 g. The height, diameter, total root length, total root surface area and biomass of two years Phoebe bournei seedlings ranged respectively as follows: 28.02-52.00 cm,4.00-5.05 mm, 189.00-299.44 cm,118.01-249.43 cm2 and 3.66-14.13 g. By principal component comprehensive evaluation, we screened Jianou in Fujian, Lishui in Zhejiang, Chishui and Zunyi in Guizhou as the ideal origin location, they occupy better growth performance in Guiyang.
Keywords:Phoebe bournei  origin location  growth variation  principal component analysis (PCA)  preliminary selection
