摘要：３Ｎ－ＰＰ（３３３）处理枳（Ｐｏｎｃｉｒｕｓｔｒｉｆｏｌｉａｔａ）砧华盛顿脐橙（ＣｉｔｒｕｓｓｉｎｅｎｓｉｓＯｓｂｅｃｋ）不同时期春、夏梢成熟叶片、幼嫩秋梢，半个月后，其吸收量一般仅占处理量的０．２％左右，被吸收的３Ｈ－ＰＰ（３３３）在大部分情况下主要滞留在处理部位。向外转运时，越远离处理部位，被转运的量越少，能运至根系的极少。土施时，根系对ＰＰ（３３３）吸收缓慢，其吸收率随时间的延长而缓慢增加，２个月后仅占处理量的０．０２５％。吸收转移至地上部的量也随时间的延长而增加。根系对ＰＰ（３３３）较敏感，根内浓度不足０．４μｇ／ｇ即可明显影响新根发生和生长。无论３Ｈ－ＰＰ（３３３）由叶、梢向根转运，还是由根向地上部转运，一般韧皮部内３Ｈ放射比活性大大高于木质部。

Abstract: The mature leaves on spring or summer shoots, young autumn shoots of Washington navel orange (Citrus sinesis) on trifoliata orange(Poncirus trifoliata) were treated with 3H-paclobutrazol(PP(333)). 15 or more days after treatment, ￣3H activity in treated plants was about 0.2% of the total treatment activity. The results showed that, in most cases, 3H activity in the plants was distributed predominantly in the treated tissues, some in other tissues, and very little in roots. The majority of ￣3H activity in st...
