摘　　要：以4年生柚木的当年生半木质化嫩枝为材料,在7月下旬,采用不同浓度IBA粉剂处理插穗,进行扦插试验。观察扦插生根的解剖结构,探讨扦插生根与愈伤组织、不定根原始体的关系,及扦插生根的类型、不定根的形成过程等。Tectona grandis L.f.is a kind of defoliated or half-defoliated tall arbor,belonging to Verbenaceae Tectona.In this softwood cuttings propagation experiment ,the half-lignified twigs of 4-year-old Tectona grandis L.f. were treated with exogenesis hormones of IBA powder in different concentrations in the last ten -day of July .The ana-tomical structure of rhizogenesis tissues of the soft-wood cutting propagation were studied ,to discuss the relationship between cutting woods rooting and callus ,primordium of adventitious roots ,and to study the type and process of ad-ventitious roots .

关 键 词：柚木 嫩枝扦插 解剖结构 愈伤组织 不定根
