Study on the Cutting Experiment of Callistemon rigidus R.Br With Different Hormone Concentrations
Through experiments,the plant growth hormone and suitable concentration suitable for the rooting of cuttings of Callistemon rigidus R.Br were studied.The control experiment was carried out with the Callistemon rigidus R.Br of the same year.3 kinds of were hormone used:indobutyric acid(IBA),indoleacetic acid(IAA),naphthaleneacetic acid(NAA),respectively configured with 50 mg/L,100 mg/L,200 mg/L,and IAA+IBA100 mg/L,IAA+NAA 100 mg/L,NAA+IBA100 mg/L.The cuttings were soaked in three concentrations of solu-tion for 5 min,and the rooting test was carried out.The rooting effects of different types and concentrations of plant growth hormone on Callistemon rigidus R.Br were studied,and the best reagent and concentration to im-prove the survival rate were screened.The effects of different plant growth hormone treatments on the cutting propagation of Callistemon rigidus R.Br showed that the survival effect of IAA(100 mg/L)was 86.7%,followed by IAA/IBA(100 mg/L),IBA(200 mg/L)and IAA(50 mg/L).The survival effect of IBA is general,and the survival effect of NAA is relatively poor.
