摘要
对福建三明明溪试验林场内的18个闽楠(Phoebe bournei)地理种源3年生林分生长性状进行分析,结果表明,苗高和地径在种源间差异具有高度统计学意义,各种源内个体也存在一定的差异,其中苗高生长量最大的为种源18(23.30cm),其次为种源7(22.21cm),表现最差的为种源6(16.42cm);地径最大的为种源9(2.82mm),其次为种源18(2.76mm),最差的是种源6(1.82mm)。经综合评价,初步认定种源15(松溪种源)为参试种源中的最优种源,同时确定了种源10(明溪种源)、种源11(大田种源)、种源1(建瓯种源)为该地区适宜的引种栽培种源。为闽楠遗传改良和速生优良家系及优良单株选择等提供理论指导,为三明及福建省闽楠造林提供更多的参考意义。
Growth traits of the 3-year-old Phoebe bournei for 18 provenances in Mingxi forest experimental Farm of Fujian Province was performed. The result showed that there were significant or extremely significant differences in tree height and diameter at basal height among different provenances,as well as in all of the individuals within provenances. The best provenances in height growth was prove-nances 18（23.30 cm）, then provenances 7（22.21 cm）, provenance 6 was lowest, while biggest increase of basal diameter was provenance 9 （2.82 cm）, followed by provenance 18,provenance 6 was the smallest in a level of 1.82 mm. Comprehensive evaluation indicated that Provenance 15 was the best provenance,and 10, 11, 15, 1 were the suitable provenances for introduction in Mingxi. The study was mean-ingful for the genetic improvement and provenance screen.
