| 摘要: |
| 对航天诱变风仙花SP2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Spss11．5统计分析软件检验了毖本假设的满足条件，进行了独立样本t检验。结果表明，航天诱变风仙花SP2代植株的叶片存在变异；试验组SP2代植株的叶片长度与对照组相比差异屉著，叶片宽度差异不显著。 |

| Analysis of blades in the SP2 mutant plants |
|

| Abstract: |
| 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. |
