| 摘 要： | 目的]为菊花简便繁殖提供参考。方法]取菊花不同生长时期的健壮枝条,插穗用高锰酸钾溶液消毒及吲哚-3-丁酸处理后进行水插培养,研究处理后插穗的生长情况。结果]4月20日扦插比4月9日扦插的整体成活率高61%。经过消毒处理的插穗比未经消毒处理的插穗成活率高30%,4月9日经过200 mg/L IBA处理12 h的插穗全部死亡,100 mg/L IBA处理12 h的插穗成活率也偏低,4月20日相同激素处理6 h,成活率显著提高。100 mg/L IBA处理的插穗生根数明显高于其他处理组。200 mg/L IBA处理的插穗生根数也略高于未经过激素处理的。结论]采用4月下旬的插穗,消毒后用100 mg/L IBA处理,可提高扦插成活率。

| Abstract: | Objective] The study was to provide reference for simple breeding of chrysanthemum.Method] The strong shoots of chrysanthemum in different growth period were taken,the cuttings were cultured by hydroponics after being disinfected by potassium permanganate solution and treated by indole-3 butyrate,the growth conditions of cuttings after treatment was studied.Result] The whole survival rate of cuttings that taken on April 20 was 61% higher than that of taken on April 9.The survival rate of cuttings that were disinfected was 30% higher than that of non-disinfection,The cuttings treated by 200 ppm IBA for 12h on April 9 were all dead,and the survival rate of cuttings that treated by 100 ppm IBA for 12h was also lower,The survival rate of cuttings treated by the same hormone for 6h on April 20 was increased significantly.The root number of cuttings treated by 100 ppm IBA was obviously higher than that of other treatment groups,treated by 200 ppm IBA was slightly higher than that of non-hormone treatment ones.Conclusion] The survival rate of cuttings could be increased when cuttings were taken in the last ten-day of April and treated by 100 ppm IBA after being disinfected. |
