摘　　要：火炬松（ＰｉｎｕｓｔａｅｄａＬ）．在皖中地区引种成功后，以其优良的生物学特性和广泛的用途深受当地群众喜爱，现已成为该地区低山丘陵重要的用材造林树种，并被列入国家世行贷款造林项目。为了定向培育“生长、材性兼优”的工业原料林，我们在原种源试验的基础上，又...The study results on the 15 a old provenance test of loblolly pine at Jingxian County of Anhui show that,there exist significant differences for the traits of tree height,stem straightness and wood density which have middle broad sense heritability,but the difference is insignificant for stem diameter,volume and stem biomass. There are close phenotypic correlations between the traits except wood density that is more independent. Provenance L8 and L25 are comprehensively selected as superior ones for pulpwood that the average phenotypic and genetic gains are 4.91% and 10.84%,3.19% and 4.01% for wood density and stem biomass respectively;L25,L6,L3 and L30 are selected for building timber,of which the phenotypic gains are 3.98%,11.19%,3.60%,6.91% and the genetic gains are 1.99 %, 7.16 %, 2.34 %,2.42% for tree height,stem straightness,wood density and stem volume respectively.
