2年生盆栽枳实生苗经0～5000ppm系列浓度PP333处理后,新梢抽发量、生长量、节间长度,主干粗度,新根发生量,根长度及单株鲜重等随处理浓度的升高而减少,但新根粗度随处理浓度增加而增加。PP333处理使新生枝叶及根中Zn含量减少,但似乎不减弱对K、Ca、Mg、Mn、Cu等元素的吸收,而P的含量相对稳定。 After 2-year-old potted Poncirus trifoliata seedlings were treated with 0 ~ 5000ppm serial concentration of PP333, the shoot emergence amount, growth amount, internode length, stem thickness, new root amount, root length, Increased and decreased, but the root thickness increased with the increase of treatment concentration. PP333 treatment reduced the content of Zn in fresh branches and roots, but did not seem to decrease the absorption of K, Ca, Mg, Mn, Cu and other elements, while the content of P was relatively stable.
