通过大叶女贞对比试验，初步发现：树高、地径均排在前10位、生长量较大的株系有3个，为12号、14号和16号；叶片冻害较轻、春季枝梢抽死长度较短、有干梢的枝条数占总枝条数的百分比较少的株系均排在前10位，在抗冻方面综合表现较好的株系有ZZ20、P2和H8。观测期内69个株系中没有发现生长量和抗冻综合表现均好的株系，可能是栽植年限较短，各方面的影响因素太多，造成调查数据的偏差，需要继续观测试验。%The contrast test of Ligustrum lucidum indicated that the tree heights, ground diameters of strains No. 12, No. 14 and No. 16 ranked in the top 10, and the three strains had a large growth amount. The strains ranked in the top 10 had such characteristics as lighter leaf frost, shorter dead spring shoot length, lesser ratio of dead shoots to the total number of branches. In cold tolerance comprehensive performance of the strains ZZ20, P2 and H8 were better. We haven’t find the strain with high growth and cold tolerance in 69 strains, maybe because of the survey data deviation resulted from short planting period and various effect factors. So the further observation test is need to do.
