4种矮化剂对樱桃番茄矮化作用研究

Study on the effect of four dwarfing materials on Lycopersicum esculentum var. cerasiforme

对 4种矮化剂对樱桃番茄的致矮作用进行了试验研究 ,结果表明 :比久 ( B9)、多效唑 ( PP3 3 3 )、缩节胺 ( Pix)和矮壮素 ( CCC)均对樱桃番茄有明显的致矮作用。其中比久矮化作用表现为节间缩短而引起的茎高降低 ,可比对照降低约2 0 %～ 30 % ,效果显著。有效作用时间 7～ 2 1d。茎粗。

The experiment result shows that the dwarfing effect of B 9, PP 333 ,Pix,CCC on Lycopersicum esculentum var.[WT5BX]cerasiforme is all significant. Especially the dwarfing effect of B 9 is most obvious and the valid period of B 9 is longer than the others. The joint of stem being shortened and the height of the plant being reduced are the result of the dwarfing effect of 4 materials.
