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 ;磷酸二氢钾可以提高瓜叶菊种子发芽率和硝酸还原酶活性
The results showed that: the mixed treatment can significantly increase the leaf chlorophyll content and nitrate reductase activity, extend the flowering, but the plant height, dry weight, the germination rate is not The effects of paclobutrazol on dwarfing and prolonged flowering were significant. Boron increased the germination rate of cineraria seeds significantly. Potassium dihydrogen phosphate increased the seed germination rate and nitrate reductase activity of cineraria
