Abstract

The [(2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1- yl)-pentan-3-ol] (paclobutrazol, PP333) measured in apple seedlings (;York Imperial' Malus domestica Borkh) was confirmed by gas chromatography-mass spectrometry. Data showed that paclobutrazol was taken up through roots and transported primarily in the xylem through the stems and accumulated in leaves. No detectable basipetal movement of paclobutrazol in apple seedlings was found.

摘要

[(2RS,3RS)-1-(4-氯苯基)-4,4-二甲基-2-(1,2,4-三唑-1-基)-戊-3-醇](多效唑,PP333)在苹果幼苗(“约克帝国”苹果 Malus domestica Borkh)中的含量通过气相色谱-质谱法进行了测定。数据表明,多效唑通过根系被吸收,并主要通过茎中的木质部向上运输,然后在叶片中积累。在苹果幼苗中未发现多效唑的可检测向基运动。
