在江苏省沿海3个试验点对24个刺槐优良无性系进行了品系比较试验。结果表明:供试刺槐优良无性系存在着明显的遗传变异,各无性系在树高、胸径指标上差异极显著或显著;刺槐优良无性系较对照(CK)有较大的速生优势:省沿海防风林试验站内试验林各无性系的主要性状指标均高于对照;如东县海堤站试点仅鲁59、鲁13两无性系树高、胸径及鲁78胸径低于对照,其余无性系均高于对照;新洋农场试点除鲁78树高、胸径及小叶槐、鲁59树高低于对照外,其余均高于对照。
Twenty-four clones of Robinia pseudoacacia were tested in three experimental sites along the coast of Jiangsu Province. The results showed that there was obvious genetic variation in elite clones of R. pseudoacacia. The differences of tree height and DBH among clones were significant or significant. The superior clones of R. pseudoacacia had more advantages in speed-up than the CK (CK) The main traits of clones in the experimental stands in the windbreak test station were all higher than those in the control. The experimental height of the Lukang 59 and Lu 13 clones was lower than that of the control, while the other clones were all high In the control; Xin Yang farms in addition to Lu 78 tree height, DBH, and small leaf Huai, Lu 59 tree height lower than the control, the rest were higher than the control.
