摘　　要：对航天诱变凤仙花SP 2代若干单株的叶片长度和宽度进行了统计分析,对试验数据进行了柯尔莫哥罗夫-斯米尔诺夫检验,计算了样本的列文统计量,并采用Spss 11.5统计分析软件检验了基本假设的满足条件,进行了独立样本t检验。结果表明,航天诱变凤仙花SP 2代植株的叶片存在变异;试验组SP 2代植株的叶片长度与对照组相比差异显著,叶片宽度差异不显著。Several SP2 mutant plants were obtained from induced Impatiens balsamina L. seeds by space flight ,and their blades were investigated in this paper. The writer calculated the K-S statistics and the levene statistics,also made use of SPSS 11.5 to have the independent-samples t test and the univariate in the prerequisite of some fundamental presumptions. From the above analysis, some conclusions were drawn： firstly,there existed variation among the blades of SP2 plants;secondly,in contrast with the cotrol group, there existed significant variation in the length of the blades of SP2 plants ,however,significant variation in the width of the blades didn＇t exist.
