摘要
在瓜叶菊生长期用不同矿质元素和多效唑喷施叶面 ,其结果表明 :混合处理能显著提高叶片叶绿素含量和硝酸还原酶的活性 ,延长花期 ,但对株高、干粒重、发芽率没有大的影响 ;多效唑有明显的矮化植株和延长花期作用 ;硼对提高瓜叶菊种子的发芽率有显著效果 ;
Spraying different mineral elements and paclobutrazol on the leaves of the florists cineraria were tested during the process of its growth.The result of experiment showed then the mixture can raise the chlorophyll contents and the mitrate reducase vigor and can last the florescence,while it has no any sideeffect on the height of the trunk,the weight of the train and the germination percentage.Paclobutrazol has an obvous role and effect of shortenoing the trunk and lasting the florescence,Boron on raising the germination percentage,and potassium phosphate monobasic on rasing the germination percentage and the mitrate reductase vigor of the florists cineraria.
