【摘要】 应用PP333、矮丰和水杨酸对紫罗兰进行叶面喷施处理,研究其对株高、花期、叶片长宽比、叶绿素含量的影响。结果表明:经PP333处理的紫罗兰株型明显矮化,经水杨酸处理的紫罗兰花期显著延长,初花期提前,但矮化效果不显著。综合效果看,叶面喷施质量浓度为0.2 mg/L的PP333对紫罗兰的作用效果较好(株高极显著矮化且未发生莲座化现象)。叶面喷施水杨酸对提高紫罗兰叶绿素含量的影响最大。更多还原

【Abstract】 The effects on plant height,florescence,leaf size and chlorophyll contents of Matthiola incana R.Br.were studied by treating with PP₃₃₃,Aifeng and SA.The results showed that PP₃₃₃ inhibited growth significantly,SA prolonged the florescence and advanced the initial time of blooming,but its dwarfing effect was not significant.It can be concluded that treatment with 0.2 mg/L by PP₃₃₃ obtained better results（The plant height was significantly dwarf,whereas no rosette appeared）.SA improved the chlorophyll contents obviously.更多还原
