摘　　要：为选育无患子优良品种,以采集的10株无患子优树的种子进行了播种试验,测定无患子优树子代苗木的生长指标,初步揭示无患子苗期生长性状的变异规律。结果表明:不同优树子代生长指标存在显著差异。各优树1 a生子代苗木的平均苗高为210.35cm,不同优树子代苗木的苗高之间存在显著差异,其中优树3号子代苗木最高。10株优树子代苗木的地径生长速率也不一致,优树3号、5号和8号相较其他优树地径增长较快。不同优树的全株总生物量均值为127.38 g,其中6号和1号优树全株干质量显著高于其他优树。优树6号、8号和1号子代苗木的壮苗指数与其他优树相比较高.In order to select and breed fine varieties of Sapindus mukorossi,the seeds of ten superior trees of Sapindus mukorossi were collected for sowing test.The growth indexes of the progeny seedlings of superior trees of Sapindus mukorossi were determined,and the variation regularity of growth traits of Sapindus mukorossi at seedling stage was preliminarily revealed.The results showed that there were significant differences in the growth indexes of different superior tree progeny.The average seedling height of one-year-old progeny seedlings of each superior tree was 210.35 cm.There were significant differences in seedling height of progeny seedlings of different superior trees,among which the seedling height of progeny seedlings of superior tree No.3 was the highest.The ground diameter growth rate of the progeny seedlings of ten superior trees was also inconsistent.The ground diameters of superior trees No.3,No.5 and No.8 increased faster than that of other superior trees.The average value of total biomass of different superior trees was 127.38 g,and the dry weights of superior trees No.6 and No.1 were significantly higher than that of other superior trees.The strong seedling indexes of the progeny seedlings of superior trees No.6,No.8 and No.1 were higher than that of other superior trees.
