Cutting Propagation in the Endangered Plant Camellia euphlebia
摘要
Abstract
[Objective]In order to provide technical support for protection and large-scale plant-ing of Camellia euphlebia ,the experiment was designed to find out the optimum conditions of cuttings rooting in this species.[Methods]By using 1 or 2-year-old branches of C. euphlebia ,and taking rooting rate,rooting number,root length,and rooting effect index as evaluation index,the effect of four factors including hormone types and concentration,trea-ting time,substrate types on rooting of cuttings with orthogonal design L9 (3 4 )were studied.[Results]The substrate types were the key factor affecting rooting of cuttings.Treatment time was second effect on rooting of cuttings. Hormone concentration was least effect on rooting of cuttings.The substrate types had sig-nificant effect on rooting effect index of cut-tings,while other 3 factors didn’t show any sig-nificant effect.The optimum treatment condi-tion is to treat cuttings with 300 mg·L-1 NAA for 12 h and taking peat soil + perlite as sub-strate.[Concusion ]The cutting propagation is feasible to carry out large-scale breeding of C. euphlebia .关键词
