摘要
豫东开封8个刺槐无性系9年生试验材料表明:参试无性系树高、胸径和材积差异达显著水平,用布雷津综合评价法对无性系进行排序,选择出1个刺槐优良无性系3—Ⅰ,9年生树高、胸径、材积分别超豫刺槐1号22 75%、27 38%、73 14%。
The paper analyzed the results of 8 nine-year-old black locust (Robina pseudoacacia L.)clones grown in Kaifeng County,eastern of Henan Province.the results showed that there were highly signififcant differences on height,D.B.H.and volume among the tested clones.With the symthetic method,one fine clone was selected.Its average height,D.B.H.volume of the nine-year-old exceeded the R.pseudoacacia CL.`Henansis'by 22.75%、27.38% and 73.14%.
