摘要
0.2、0.4、1.0及1.5mg·L-14个浓度的N-(2-氯-4-吡啶基)-N'-苯基脲(CPPU)对无疣墙藓的孢子萌发没有显著影响,但抑制绿丝体伸长和侧枝生成,对芽体的分化有明显的促进,且芽体发生数随浓度升高而增加。
The spores of Tortula mucronifolia Schwaegr. were treated with four different concentrations （0.2, 0.4, 1.0 and 1.5 mg·L^-1） of N-（2-chloro-4-pyridyl）-N＇-phenylurea （CPPU）. The results showed that CPPU had no evident effect on the spore germination, but inhibited the chloronema straight growth and branch formation; CPPU could promote bud differentiation significantly, and the numbers of bud increased with the increase of concentrations of CPPU.
