摘　　要：本实验采用不同浓度SA、TDZ、6-BA和GA3处理紫薇种子,在恒温25℃全光照的条件下,研究了紫薇种子的萌发情况和幼苗的株高、鲜重、叶面积.结果表明:恒温25℃条件下,1-15mg/L范围内SA处理的种子发芽力较低,幼苗长势较弱.四种植物生长物质对比得出GA3处理的种子总体效果最好,其次是TDZ处理的种子效果明显.尤其1 000mg/L GA3的浓度下处理的种子效果最佳.Lagerstroemia indica seeds were processed by different levels of SA,TDZ,6-BA and GA3 in this experiment.During the 25 ℃ light conditions,we researched seeds germinate and shoots,fresh,leaf area of Lagerstroemia indica.The result showes that there is lower sprout power and weaker growing within 1-15 mg/L of SA.Compared with others the young plants are growing best in deal with GA3 the better than TDZ.It has the best overall effect of the seeds which was dealed with 1 000 mg/L GA3 in the 25 ℃ conditions.
