摘　　要： ABT +S3 3 0 7处理云南甜竹 (Dendrocalamusspp.)插条 ,提高了插条蔗糖酶的活性 ,明显减少了基部和相邻第 1节蔗糖和淀粉的含量 ,基部还原糖含量明显高于对照。随着不定根的生长 ,生根处理促进了3H 葡萄糖从标记部位向插条基部的转运 ,同时还增加了基部和不定根的3H 葡萄糖向结构物的转化 ,不定根碳水化合物含量较高 ,根系还原活性较强 ,这有利于不定根的发生和生长。 Application of ABT+S3307 to the cuttings of Dendrocalamus spp. promoted the sucrase activity.The contents of sucrose and starch in the cuttings based and the first node were decreased.Compared with the control,the content of reducing sugar was increased obviously in the cutting based.The transportation of 3H gulcose from labeled site to the base in treated cuttings was increased with the adventitious root formation.At the same time,the contents of structural substance in the cuttings based and the adventitious root were raised.The high content of carbohydrate and reducting activity in the adventitious root were available for growth of the roots.
