摘　　要：为了探明植物生长调节剂不同浓度对凤仙花种子的萌发及根生长的影响,使用6-BA、NAA、GA3对凤仙花种子进行处理,记录种子萌发的情况并测量根的生长长度。结果表明:150mg·L-1 GA3溶液处理过的凤仙花种子发芽率最高,200mg·L-1 GA3溶液处理过的根的生长速度最快。In order to explore the effect of different concentrations of plant growth regulators on seed germination and root growth of Impatiens balsamina.Take a text on I.balsamina seeds were soaking by 6-BA,NAA and GA3,the seed germination and root growth were determined.The results showed that the best condition for seed germination was 150mg·L-1 NAA,the best condition for fastest root growth was 200mg·L-1 GA3.
