Abstract
Objective] The aim was to study explant induction relevant technology of Eucalyptus urophylla ×E.grandis three clones.[Meth-od] The optimal collection season, sampling part, disinfection time and concentration of plant growth regulator(6-BA) was selected, so as to im-prove germination rate of explants of Eucalyptus urophylla × E.grandis clones.[ Result] The spring and autumn were the optimal seasons for the explant induction, semi-lignified branches was the most suitable part of explant sampling , the most appropriate disinfection duration with mer-curic chloride is 7 minutes for DH32-26 and DH32-28, and 5 minutes for DH32-29.6-BA1.0 mg/L and NAA0.4 mg/L as plant growth regulator combination was good for explant induction which with the best germination rate.[Conclusion] In order to improve the successful rate of explant induction, a comprehensive consideration should be made in terms of the collection season, sampling part, disinfection time and plant growth reg-ulator combination.The study can provide theoretical basis for rapid propagation of Eucalyptus urophylla × E.grandis seedlings.关键词
