Influence of three factors on the rooting and emergence of Begonia rex Putz.
In this study we explored the rooting and emergence of Begonia rex Putz.under the conditions of differ-ent substrates,different hormones and different hormone concentrations,and determined the most suitable method of propagation by cutting for Begonia rex.The experiment analyzed 42 treatment groups with the interacting of the three factors,and it was found that the rooting rate,rooting quality,emergence rate and emergence quality varied greatly among the treatment groups.C9 and C33 had the highest emergence rate and strong roots and seedlings.In conclusion,the most suitable treatment is as follows:vermiculite as the substrate with 200 mg/L NAA,or perlite+water moss(1∶1)as the substrate with 200 mg/L IBA.
